INSTALLATION GUIDE
QUICK INSTALL
This manual contains detailed operating instructions for all aspects of the FSR Series.
The following condensed instructions are provided to assist the operator in getting
the instrument started up and running as quickly as possible. This pertains to basic
operation only. If specic instrument features are to be used or if the installer is
unfamiliar with this type of instrument, refer to the appropriate section in the
manual for complete details.
Note: The following steps require information supplied by the meter itself, so it is necessary to
supply power to the unit, at least temporarily, to obtain setup information.
1 - Transducer Location
1. In general, select a mounting location on the piping system with a minimum of
10 pipe diameters (10x the pipe inside diameter) of straight pipe upstream and 5
straight diameters downstream. See Table 2.1 for additional congurations.
2. Select a mounting method for the transducers based on pipe size and liquid
characteristics. See Table 2.2. Transducer congurations are illustrated in Figure
Q.1 below. The V-mount conguration is usually the rst choice, with W-mount
and Z-mount used if needed to boost signal strength.
Note: All FST1xxxx, FST2xxxx, and FST3xxxx transducers use V-Mount conguration.
3. Enter the following data into the meter via the integral keypad or the software
utility (if not entered by the factory)
1. Transducer mounting method
2. Pipe O.D. (Outside Diameter)

INTRODUCTION
General
The Veris ultrasonic ow meter is designed to measure the uid velocity of liquid
within a closed conduit. The transducers are a non-contacting clamp-on or clamp-
around type that does not foul and is easy to install.
The Veris family of transit time ow meters utilize two transducers that function
as both ultrasonic transmitters and receivers. The transducers are clamped on
the outside of a closed pipe at a specic distance from each other. The transducers
can be mounted in V-Mount where the sound transverses the pipe two times,
W-Mount where the sound transverses the pipe four times, or in Z-Mount where the
transducers are mounted on opposite sides of the pipe and the sound crosses the pipe
once. The selection of mounting method is based on pipe and liquid characteristics
that both have an eect on how much signal is generated. The ow meter operates
by alternately transmitting and receiving a frequency modulated burst of sound
energy between the two transducers and measuring the time interval that it takes
for sound to travel between the two transducers. The dierence in the time interval
measured is directly related to the velocity of the liquid in the pipe.

INSTALLATION GUIDE
PART 1 - MONITOR INSTALLATION
After unpacking, save the shipping carton and packing materials in case the
instrument is stored or re-shipped. Inspect the equipment and carton for damage. If
there is evidence of shipping damage, notify the carrier immediately.
Mount the enclosure in an area that is convenient for servicing, calibration, and
observation of the LCD readout.
1. Locate the monitor within the length of transducer cables supplied. If this is
not possible, it is recommended that the cable be exchanged for one that is of
proper length. If additional cable is added, utilize RG59 75 Ω coaxial cable and
BNC connections. Transducer cables that are up to 990 feet (300 meters) can be
accommodated.
2. Mount the monitor in a location:
• Where little vibration exists.
• That is protected from corrosive uids.
• That is within the monitor’s ambient temperature limits -40 to +185°F
(-40 to +85°C).
• That is out of direct sunlight. Direct sunlight may increase monitor
temperature to above the maximum limit.
3. Mounting - Refer to Figure 1.2 for enclosure and mounting dimension details.
Ensure that enough room is available to allow for door swing, maintenance and
conduit entrances. Secure the enclosure to a at surface with two appropriate
fasteners.

INSTALLATION GUIDE
PART 2 - TRANSDUCER INSTALLATION
General
The FST transducers contain piezoelectric crystals for transmitting and receiving
ultrasonic signals through walls of liquid piping systems. FST transducers are
relatively simple and straightforward to install, but spacing and alignment of the
transducers is critical to the system’s accuracy and performance. Take care to ensure
that these instructions are carefully executed. FST1, FST2, and FST3 small pipe
transducers have integrated transmitter and receiver elements that eliminate the
requirement for spacing measurement and alignment.
Mounting of the FST4 and FST5 clamp-on ultrasonic transit time transducers is a
three-step process:
1. Select the optimum location on a piping system.
2. Enter the pipe and liquid parameters into either the software utility or key the
parameters into the transmitter using the keypad. The software utility or the
monitor’s rmware calculates proper transducer spacing based on these entries.
3. Pipe preparation and transducer mounting.
BTU meters require two RTDs to measure heat usage. The ow meter utilizes 1,000 Ω,
three-wire, platinum RTDs in two mounting styles. Surface mount RTDs are available
for use on well insulated pipes. Mounting the RTD in an uninsulated area causes
inconsistent temperature readings. Insertion (wetted) RTDs should be sued in these
areas instead.
Step 1 - Mounting Location
The rst step in the installation process is the selection of an optimum location for
the ow measurement to be made. This requires a basic knowledge of the piping
system and its plumbing.
An optimum location is dened as:
• A piping system that is completely full of liquid when measurements are
being taken. The pipe may become completely empty during a process
cycle, which results in the error code 0010 (Low Signal Strength) being
displayed on the ow meter while the pipe is empty. This error code clears
automatically once the pipe rells with liquid. It is not recommended to
mount the transducers in an area where the pipe may become partially
lled. Partially lled pipes cause erroneous and unpredictable operation
of the meter.
• A piping system that contains lengths of straight pipe such as
those described in Table 2.1. The optimum straight pipe diameter
recommendations apply to pipes in both horizontal and vertical
orientation. The straight runs in Table 2.1 apply to liquid velocities that
are nominally 7 FPS (2.2 MPS). As liquid velocity increases above this
nominal rate, the requirement for straight pipe increases proportionally.
• Mount the transducers in an area where they will not be inadvertently
bumped or disturbed during normal operation.
• Avoid installations on downward owing pipes unless adequate
downstream head pressure is present to overcome partial lling of or
cavitation in the pipe.
• Note: Do not cut transducer cables to alter length. This will
void the factory warranty. Cables are available in several
lengths. Assess the installation location prior to ordering to
determine the optimum length. If the wrong length is ordered,
contact the factory.

Table 2.1 - Piping Conguration and Transducer Positioning
The ow meter system provides repeatable measurements on piping systems that do
not meet these requirements, but accuracy of these readings may be inuenced to
various degrees.
Step 2 - Transducer Spacing
Transit time ow meters can be used with two dierent transducer types. Meters
that utilize the FST4 and FST5 transducer sets consist of two separate sensors
that function as both ultrasonic transmitters and receivers. FST1, FST2, and FST3
transducers integrate both the transmitter and receiver into one assembly that xes
the separation of the piezoelectric crystals. These transducers are clamped on the
outside of a closed pipe at a specic distance from each other.
The FST4 and FST5 transducers can be mounted in:
W-Mount where the sound traverses the pipe four times. This mounting
method produces the best relative travel time values but the weakest signal
strength.
V-Mount where the sound traverses the pipe twice. V-Mount is a compromise
between travel time and signal strength.
Z-Mount where the transducers are mounted on opposite sides of the pipe
and the sound crosses the pipe once. Z-Mount will yield the best signal
strength but the smallest relative travel time.

For further details, reference Figure 2.1. The appropriate mounting conguration is
based on pipe and liquid characteristics. Selection of the proper transducer mounting
method is not entirely predictable and many times is an iterative process. Table 2.2
contains recommended mounting congurations for common applications. These
recommended congurations may need to be modied for specic applications
if such things as aeration, suspended solids, out of round piping or poor piping
conditions are present. Use of meter diagnostics in determining the optimum

Step 3 - Entering Pipe and Liquid Data
The system calculates proper transducer spacing by utilizing piping and liquid
information entered by the user. Enter this information via the keypad or via the
optional software utility.
The best accuracy is achieved when transducer spacing is exactly what the meter
calculates, so use the calculated spacing if signal strength is satisfactory. If the pipe is
not round, the wall thickness is not correct, or the actual liquid being measured has a
dierent sound speed than the liquid programmed into the transmitter, the spacing
can vary from the calculated value. If that is the case, place the transducers sat the
highest signal level observed by moving the transducers slowly around the mount
area.
Note: Transducer spacing is calculated on “ideal” pipe. Ideal pipe is almost never found so the
transducer spacing distances may need to be altered. An eective way to maximize signal strength
is to congure the display to show signal strength, x one transducer on the pipe and then starting
at the calculated spacing, move the remaining transducer small distances forward and back to
nd the maximum signal strength point.
Important! Enter all of the data on this list, save the data, and reset the
meter before mounting transducers.

The following information is required before programming the instrument:

Pipe wall thickness Pipe material
Pipe sound speed1Pipe relative roughness1
Pipe liner thickness (if present) Pipe liner material (if present)
Fluid type Fluid sound speed1
Fluid viscosity1Fluid specic gravity1
Note: Much of the data relating to material sound speed, viscosity, and specic gravity is
pre-programmed into the ow meter. This data only needs to be modied if it is known that a
particular applications data varies from the reference values. Refer to Part 4 of this manual for
instructions on entering conguration data into the ow meter via the monitor’s keypad. Refer to
Part 5 for data entry via the software.
1 Nominal values for these parameters are included within the operating system. The nominal
values may be used as they appear or may be modied if exact system values are known.
After entering the data listed above, the meter calculates proper transducer spacing
for the particular data set. This distance is in inches if it is congured in English units,
or millimeters if congured in metric units.
Step 4 - Transducer Mounting
Pipe Preparation
Before mounting the transducers onto the pipe surface, clean an area slightly larger
than the at surface of each transducer to eliminate all rust, scale and moisture.
For pipes with rough surfaces, such as ductile iron pipe, wire brush the surface to a
shiny nish. Paint and other coatings need not be removed unless aked or bubbled.
Plastic pipes typically do not require surface preparation other than soap and water
cleaning.
Properly orient the transducers and spaced them on the pipe to provide optimum
reliability and performance. On horizontal pipes, when Z-Mount is required, mount
the transducers 180 radial degrees from one another and at least 45 degrees from
the top-dead-center and bottom-dead-center of the pipe. See Figure 2.2 Also see
Z-Mount Transducer Installation. On vertical pipes the orientation is not critical.
Measure the spacing between the transducers using the two spacing marks on the
sides of the transducers. These marks are approximately 0.75” (19 mm) back from the
nose of the FST4/FST5 transducers. See Figure 2.3.
Mount FST1, FST2, and FST3 transducers with the cable exiting within ±45 degrees
of the side of a horizontal pipe. See Figure 2.2. On vertical pipes the orientation does
not apply.

silicone-based grease is used as an acoustic couplant, but any grease-like substance
that is rated not to “ow” at the temperature that the pipe may operate at will be
acceptable. For pipe surface temperature over 130°F (55°C) Sonotemp® (P.N. D002-

Transducer Positioning
1. Place the upstream transducer in position and secure with a mounting strap. Place
straps in the arched groove on the end of the transducer. A screw is provided to
help hold the transducer onto the strap. Tighten the transducer strap securely.
2. Place the downstream transducer on the pipe at the calculated transducer spacing.
See Figure 2.5. Apply rm hand pressure. If signal strength is greater than 5,
secure the transducer at this location. If the signal strength is not 5 or greater
then using rm hand pressure, slowly move the transducer both towards and
away from the upstream transducer while observing signal strength. Clamp
thetransducer where the highest signal strength is observed. Signal levels much
less than 5 may not yield acceptable data.
Note: Signal strength readings update only every few seconds, so it is advisable to move
the transducer 1/8”, wait, see if signal is increasing or decreasing and then repeat until
the highest level is achieved.
3. If after adjustment of the transducers the signal strength does not rise to above 5,
then select an alternate transducer mounting method. If the mounting method
was W-Mount, then re-congure the monitor for V-Mount, move the downstream
transducer to the new spacing distance and repeat Step 4.

Small Pipe Transducer Installation
The small pipe transducers are designed for specic pipe outside diameters. Do not
attempt to mount a transducer onto a pipe that is either too large or too small for the
transducer.
FST1, FST2, and FST3 installation consists of the following steps:
1. Apply a thin coating of acoustic coupling grease to both halves of the transducer
housing where the housing will contact the pipe. See Figure 2.6.

2. On horizontal pipes, mount the transducer in an orientation such that the cable
exits at ±45 degrees from the side of the pipe. Do not mount with the cable
exiting on either the top or bottom of the pipe. On vertical pipes the orientation
does not matter. See Figure 2.2.
3. Tighten the wing nuts or “U” bolts so that the acoustic coupling grease begins to
ow out from the edges of the transducer or from the gap between the transducer
halves. Do not over tighten.
4. If signal strength is less than 5, remount the transducer at another location on the
piping system.
5. Conguration Procedure:
a. Establish communications with the transit tme meter. See Part 5 -

Mounting Transducers in Z-Mount Configuration
Installation on larger pipes requires careful measurements of the linear and radial
placement of the FST4 and FST5 transducers. Failure to properly orient and place the
transducers on the pipe may lead to weak signal strength and/or inaccurate readings.
1. Place the transducers on opposite sides of the pipe. This distance around the pipe
is calculated by multiplying the pipe diameter by 1.57. The transducer spacing
along the pipe is the same as found in the Transducer Positioning section.
2. For FST4 and FST5 transducers, place a single bead of couplant, approximately ½
inch (12 mm) thick, on the at face of the transducer. See Figure 2.4. Generally,
a silicone-based grease is used as an acoustic couplant, but any good quality
grease-like substance that is rated to not “ow” at the temperature that the pipe
may operate at is acceptable.
3. Place the upstream transducer in position and secure with a stainless steel strap
or other fastening device. Place straps in the arched groove on the end of the
transducer. A screw is provided to help hold the transducer onto the strap. Tighten
transducer strap securely. Larger pipes may require more than one strap to reach
the circumference of the pipe.
4. Place the downstream transducer on the pipe at the calculated transducer spacing.
See Figure 2.7. Using rm hand pressure, slowly move the transducer both towards
and away from the upstream transducer while observing signal strength. Clamp
the transducer at the position where the highest signal strength is observed.
Signal strength of between 5 and 98 is acceptable. The factory default signal
strength setting is 5, however there are many application specic conditions that
may prevent the signal strength from attaining this level.
A minimum signal strength of 5 is acceptable as long as this signal level is
maintained under all ow conditions. On certain pipes, a slight twist to the
transducer may cause signal strength to rise to acceptable levels.
5. Certain pipe and liquid characteristics may cause signal strength to rise to greater
than 98. At this level, the signals may saturate the input ampliers and cause
erratic readings. To lower the signal strength, change the transducer mounting
method to the next longest transmission path. For example, if there is excessive
signal strength and the transducers are mounted in a Z-Mount, try changing to
V-Mount or W-Mount. Finally you can also move one transducer slightly o line
with the other transducer to lower signal strength.
6. Secure the transducer with a stainless steel strap or other fastener.

PART 3 - INPUTS/OUTPUTS
General
The FSR1 is available in two congurations: the ow model and the energy model.
The ow model is equipped with a 4-20 mA output, two open collector outputs, a
rate frequency output, and RS-485 communications using the Modbus RTU command
set. The energy version has inputs for two 1,000 Ω RTD sensors in place of the rate
frequency and alarm outputs. This version allows the measurement of pipe input and
output temperatures for calculating energy usage calculations.
4-20 mA Output
The 4-20 mA output interfaces with most recording and logging systems by
transmitting an analog current signal that is proportional to system ow rate. The
4-20 mA output is internally powered (current sourcing) and can span negative to
positive ow/energy rates.
For AC powered units, the 4-20 mA output is driven from a +15 VDC source located
within the meter, isolated from earth ground connections. The AC powered model
accommodates loop loads up to 400 Ω. DC powered meters utilize the DC power
supply voltage to drive the current loop. The current loop is not isolated from DC
ground or power. Figure 3.1 shows graphically the allowable loads for various input
voltages. The combination of input voltage and loop load must stay within the
shaded area of Figure 3.1.

Signal Strength Alarm
The SIG STR alarm provides an indication that the signal level reported by the
transducers has fallen to a point where ow measurements may not be possible.
It can also be used to indicated that the pipe has emptied. Like the rate alarm
described previously, the signal strength alarm requires that two points be entered,
establishing an alarm deadband. The ON value must be lower than the OFF value. If a
deadband is not established and the signal strength decreases to approximately the
value of the switch point, the output may “chatter.”
Error Alarm Outputs
When a control output is set to ERROR mode, the output activates when an error
causes the meter to stop measuring reliably. See the Appendix of this manual for a list
of potential error codes.
Set the on/o values for the Rate Alarm and Signal Strength Alarm using either the
keypad or the software utility.
Typical control connections are illustrated in Figure 3.4. Please note that only

A single-point ow rate alarm places the ON setting slightly higher than the OFF
setting, establishing a switch deadband. If a deadband is not established, switch
chatter (rapid switching) may result if the ow rate is very close to the switch point.

cooling systems. The RTDs are attached at the factory to a simple plug-in connector
eliminating the possibility of mis-wiring. Simply install the RTDs on or in the pipe as
recommended, and then plug the RTDs into the meter. The surface mount versions

Installation of Surface Mount RTDs
Only use surface mount RTDs on well insulated pipe. Installing the RTD in an
uninsulated area causes inconsistent temperature readings.
Select areas on the supply and return pipes to mount the RTDs. Remove or peel back
the insulation all the way around the pipe in the installation area. Clean an area
slightly larger than the RTD down to bare metal on the pipe.
Place a small amount of heat sink compound on the pipe in the RTD installation
location. See Figure 3.11. Press the RTD rmly into the compound. Fasten the RTD to
the pipe with the included stretch tape.
Frequency Output [FSRxxx1x only]
The frequency output is an open-collector transistor circuit that outputs a pulse
waveform that varies proportionally with ow rate. This type of frequency output is
also know as a “Rate Pulse” output. The frequency output is proportional to the max
ow rate entered into the meter. The maximum output frequency is 1000 Hz.
In addition to the control outputs, the frequency output can be used to provide total
information by use of a K-factor that relates the number of pulses from the frequency
output to the number of accumulated pulses that equates to a specic volume.
This relationship is described by the following equation: K-factor = 60,000 / full scale
units. The 60,000 relates to measurement units in volume/min. Measurement units in
seconds, hours or days would require a dierent numerator.
If the frequency output is to be used as a totalizing output, then the meter and the
receiving instrument must have identical K-factor values programmed into them
to ensure that accurate readings are recorded by the receiving instrument. Unlike
standard mechanical ow meters such as turbines, gear or nutating disk meters, the
K-factor can be changed by modifying the MAX RATE ow rate value.
Note: For a full treatment of K-factors please see the Appendix of this manual.
There are two frequency output types available:
1.) Turbine meter simulation - This option is utilized when a receiving
instrument is capable of interfacing directly with a turbine ow meter’s
magnetic pickup. The output is a relatively low voltage AC signal whose
amplitude swings above and below the signal ground reference. The
minimum AC amplitude is approximately 500 mV peak-to-peak. To activate
the turbine output circuit, turn SW4 OFF .

500 mVp-p
Figure 3.7 - Frequency Output Waveform (Simulated Turbine)
2.) Square-wave frequency - This option is utilized when a receiving
instrument requires that the pulse voltage level be either of a higher
potential and/or referenced to DC ground. The output is a square-wave with
a peak voltage equaling the instrument supply voltage when the SW3 is ON.
If desired, an external pull-up resistor and power source can be utilized by
leaving SW3 OFF. Set SW4 to ON for a square-wave output.

RS-485
The RS-485 feature allows up to 126 metering systems to be placed on a single three-
wire cable bus. Each meter is assigned a unique numeric address that allows all of the
meters on the cable network to be independently accessed. A Modbus RTU command
protocol is used to interrogate the meters. An explanation of the command structure
is detailed in the APPENDIX of this manual. Flow rate, total, signal strength and
temperature (if so equipped) can be monitored over the digital communications bus.
Baud rates up to 9600 and cable lengths to 5,000 feet (1,500 meters) are supported
without repeaters or “end of line” resistors.

Installation of Insertion RTDs
Insertion RTDs are typically installed through ¼ inch (6 mm) compression ttings
and isolation ball valves. Insert the RTD suciently into the ow stream such that a
minimum of ¼ inch (6 mm) of the probe tip extends into the pipe diameter. Only use
insertion (wetted) RTDs on pipes that are not insulated.
Mount RTDs within ±45 degrees of the side of a horizontal pipe. On vertical pipes the
orientation is not critical. Route the RTD cables back to the ow meter and secure the
cable so that it will not be pulled on or abraded inadvertently.
If the cables are not long enough to reach the meter, route the cables to an electrical
junction box and add additional cable from that point. Use three-wire shielded cable,
such as Belden® 9939 or equal, for this purpose.
Note: Adding cable adds to the resistance the meter reads and may have an eect on absolute
accuracy. If cable is added, ensure that the same length is added to both RTDs to minimize errors
due to changes in cable resistance.

INSTALLATION GUIDE
PART 4 - STARTUP AND CONFIGURATION
Before Starting the Instrument
Note: Flow meter systems require a full pipe of liquid before a successful start-up can be
completed. Do not attempt to make adjustments or change congurations until a full pipe is
veried.
Note: If Dow 732 RTV was used to couple the transducers to the pipe, the adhesive must be
fully cured before readings are attempted. Dow 732 requires 24 hours to cure satisfactorily. If
Sonotemp® acoustic coupling grease was utilized as a couplant, curing is not required.
Instrument Startup
1. Verify that all wiring is properly connected and routed, as described in Part 1 of
this manual.
2. Verify that the transducers are properly mounted, as described in Part 2 of this
manual.
3. Apply power. The display briey shows a software version number and then all of
the segments illuminate in succession.
Important!: In order to complete the installation of the ow meter, the
pipe must be full of liquid.
To verify proper installation and ow measurement operation:
1. Go to the SER MENU and conrm that signal strength (SIG STR) is between 5 and
98. If the signal strength is lower than 5, verify that proper transducer mounting
methods and liquid/pipe characteristics have been entered. To increase signal
strength, if a W-Mount transducer installation was selected, re-congure for a
V-Mount installation (standard from factory); if V-Mount was selected, re-
congure for Z-Mount.
Note: Mounting conguration changes apply only to FST4, FST5 transducer sets.
2. Verify that the actual measured liquid sound speed is within 2% of the value
entered as FLUID SS in the BSC MENU. The measured liquid sound speed (SSPD
FPS and SSPD MPS) is displayed in the SER MENU. The pipe must be full of liquid in
order to make this measurement.
Keypad Programming
Congure units with keypads using the keypad interface or by using the Windows®
compatible software utility. Units without a keypad can only be congured using the
software utility. See Part 5 of this manual for software details. Of the two methods
of conguration, the software utility provides more advanced features and oers
the ability to store and transfer meter congurations between meters. All entries
are saved in non-volatile ash memory and are retained indenitely in the event of
power loss.
The four-key tactile feedback keypad interface allows the user to view and change
conguration parameters used by the operating system.
Keypad
Mode
Indicators
Figure 4.1 - Keypad Interface
1. Press the MENU key from RUN mode to enter PROGRAM mode. Press the MENU key
in PROGRAM mode to exit from conguration parameter selection and menus. If
changes to any conguration parameters are made, the user is prompted with a
SAVE? when returning to RUN mode. Choose YES to save the new parameters in
program memory.
2. The arrow ▼ keys are used to scroll through menus and conguration
parameters. The arrow keys are also used to adjust parameter numerical values.
3. The ENTER key functions are:
• Pressed from the RUN mode to view the current software version
operating in the instrument.
• Used to access the conguration parameters in the various menus.
• Used to initiate changes in conguration parameters.
• Used to accept conguration parameter changes.
Menu Structure
The ow meter rmware uses a hierarchical menu structure. A map of the user
interface is included in the Appendix of this manual. The map provides a visual path
to the conguration parameters that users can access. Employ this tool each time
conguration parameters are accessed or revised.
The seven menus used in the software are as follows:
Menu Description
BSC Basic. Contains all of the conguration parameters necessary to initially program
the meter to measure ow.
CH1 Channel 1. Congures the 4-20 mA output.
CH2 Channel 2. Congures the type and operating parameters for channel 2 output
options. Channel 2 parameters are specic to the model used.
SEN Sensor. Used to select the sensor type (i.e. FST1, FST2, etc.).
SEC Security. Used for resetting totalizers, returning ltering to factory settings, and
revising the security password.
SER Service. Contains system settings used for advanced conguration and zeroing
the meter on the pipe.
DSP Display. Used to congure meter display functions.

INSTALLATION GUIDE
BSC Menu -- Basic Menu
The BASIC menu contains all of the conguration parameters necessary to make the
meter operational.
1. Units Selection
UNITS -- Programming Unit Selection (Choice): ENGLSH (Inches), METRIC
(Millimeters)
Installs a global measurement standard into the memory of the instrument. The
choices are either English or Metric units.
Select ENGLSH if all congurations (pipe sizes, etc.) are to be made in inches. Select
METRIC if the meter is to be congured in millimeters.
The ENGLSH/METRIC selection also congures the meter to display sound speeds in
pipe materials and liquids as either feet per second (FPS) or meters per second (MPS),
respectively.
Important!: If the UNITS value is changed, save the entry and reset the instrument
(power cycle or enter System Reset SYS RSET) to initiate the change in operating
units. Failure to save and reset the instrument causes improper transducer spacing
calculations and improper measurements.
2. Address
ADDRESS -- Modbus Address (Value): 1-126
Note: This is for the RS-485 connection only. The Modbus TCP/IP address is set via the integrated
HTML application in the Ethernet port

10. Pipe Roughness
PIPE R -- Pipe Material Relative Roughness (Value): Unitless Value
The meter provides ow prole compensation in its ow measurement calculation.
The ratio of average surface imperfection as it relates to the pipe internal diameter is
used in this compensation algorithm and is found using the following formula:
Pipe R = (linear RMS of the pipe’s internal wall surface) / (inner diameter of pipe)
If a pipe material was chosen from the PIPE MAT list, a nominal value for relative
roughness in that material is automatically loaded. Revise this value as needed for a
given application.
11. Liner Thickness
LINER T -- Pipe Liner Thickness (Value): ENGLSH (Inches), METRIC (Millimeters)
If the pipe has a liner, enter the pipe liner thickness. Enter this value in inches if

the appropriate material from the list or select OTHER if the liner material is not
listed.
13. Liner Sound Speed
LINER SS -- Speed of Sound in the Liner (Value): ENGLSH (Feet per Second), METRIC
(Meters per Second)
Allows adjustments to be made to the speed of sound value, shear or transverse
wave, for the pipe wall. If the UNITS value was set to ENGLSH, the entry is in FPS (feet
per second). METRIC entries are made in MPS (meters per second).
If a liner was chosen from the LINER MA list, a nominal value for speed of sound
in that media is automatically loaded. Revise this value as needed for a given
application.
14. Liner Roughness
LINER R -- Liner Material Relative Roughness (Value): Unitless Value
Provides ow prole compensation in its ow measurement calculation. The ratio of
average surface imperfection as it relates to the pipe internal diameter is used in this
compensation and is found by using the following formula.
Liner R = (linear RMS of the liner’s internal wall surface) / (inner diameter of liner)
If a liner material was chosen from the LINER MA list, a nominal value for relative
roughness in that material is automatically loaded. Revise this value as needed for a
given application.

the appropriate liquid from the list or select OTHER if the liquid is not listed.
16. Fluid Sound Speed
FLUID SS -- Speed of Sound in the Fluid (Value): ENGLSH (Feet per Second), METRIC
(Meters per Second)
Allows adjustments to be made to the speed of sound entry for the liquid. If the
UNITS value was set to ENGLSH, the entry is in FPS (feet per second). METRIC entries
are made in MPS (meters per second).
If a uid was chosen from the FL TYPE list, a nominal value for speed of sound in that
media is automatically loaded. Revise this value as needed for a given application.
If OTHER was chosen as FL TYPE, a FLUID SS will need to be entered. A list of alternate
uids and their associated sound speeds is located in the Appendix located at the
back of this manual.
Fluid sound speed may also be found using the Target DBg Data screen available in
the software utility. See Part 5.
17. Fluid Viscosity
FLUID VI -- Absolute Viscosity of the Fluid (Value - cP)
Allows adjustments to be made to the absolute viscosity of the liquid in centipoise.
Flow meters utilize pipe size, viscosity and specic gravity to calculate Reynolds
numbers. Since the Reynolds number inuences ow prole, the meter must
compensate for the relatively high velocities at the pipe center during transitional or
laminar ow conditions. The entry of FLUID VI is utilized in the calculation of Reynolds
and the resultant compensation values.
If a uid was chosen from the FL TYPE list, a nominal value for viscosity in that media
is automatically loaded. Revise this value as needed for a given application.
If OTHER was chosen as FL TYPE, then a FLUID VI must also be entered. A list of
alternate uids and their associated viscosities is located the Appendix located at the
back of this manual.
