1. INTRODUCTION
1.1. SYSTEM DESCRIPTION
Functions and features
The flow rate / totalizer model F110-A is a microprocessor driven instrument designed to display the
flow rate, the total and the accumulated total.
This product has been designed with a focus on:
▪ultra-low power consumption to allow long-life battery powered applications (type PB/PC);
▪intrinsic safety for use in hazardous applications (type XI),
▪ability to process all types of flowmeter signals;
▪transmitting possibilities with analog, pulse and communication outputs;
▪several mounting possibilities with GRP or aluminum enclosures for industrial surroundings.
Flowmeter input
This manual describes the unit with a (0)4-20mA input from the flowmeter. Other versions are
available to process pulse signals.
One flowmeter with a (0)4-20mA output can be connected to the F110-A. To power the sensor,
several options are available.
Standard outputs
▪Pulse output to transmit a pulse that represents a totalized quantity as programmed.
▪Linear (0)4-20mA or 0-10V analog output to represent the actual flow rate as programmed. The
(0)4-20mA or 0-10V signal limits can be tuned.

Configuration
The F110-A is designed for use in many types of applications. For that reason, a setup menu is
available to program the F110-A according to your specific requirements.
The setup includes several important features, such as span, engineering units, signal selection,
power management (to extend battery life-time), etc. All settings are stored in a non-volatile memory
and therefore kept in the event of a power failure or an exhausted battery.
Display information
The unit has a LCD with (optional) backlight to show the process information, status and alarm messages.
The display refresh rate is programmed in the setup menu.
At a key press, the display refresh rate will switch to FAST for 30 seconds. When 'OFF' is selected,
the display goes off after 30 seconds after the last key press. The display temporarily comes on after
a key press.
A backup of the total and accumulated total in EEPROM memory is made every minute.
Options
The following options are available: isolated or active (0)4-20mA / 0-10V analog output, full Modbus
communication RS232/485/TTL (also battery powered), intrinsic safety, mechanical relay or active
output, power- and sensor-supply options, panel -mount, wall-mount and weather-proof enclosures,
flame proof enclosure and LED backlight.

2.2. OPERATOR INFORMATION AND FUNCTIONS
In general, the F110-A operates in the operator
mode. The shown information depends on the
settings which are made in the setup menu.
The signal from the connected sensor is processed
by the F110-A in the background, independent from
the selected display refresh rate.
Fig. 3: Process information (typical)
For the Operator, the following functions are available:
▪Display flow rate / total or flow rate
▪This is the main display information of the F110-A . After the selection of any other information, it
will always return to this main display automatically. Total is shown on the upper line of the
display and flow rate on the bottom line. When selected in the setup menu, the display shows
the flow rate only. When you press the select key, the total shows momentarily.
▪Clear total
▪The value for total can be reset. To do so, press the CLEAR/key twice. When the key is
pressed once, the text "PUSH CLEAR" is shown. To avoid a reset at this stage, press another
key other than the CLEAR/key or wait for 20 seconds. A reset of the total does not influence
the accumulated total.
Type IB: When a Normally Closed (NC) contact is used, the local clear total function is
disabled and a clear total is only possible with the external reset command.
▪Display accumulated total
▪When the SELECT/key is pressed, total and accumulated total are shown. The accumulated
total cannot be reset. The value will count up to 99,999,999,999. The unit and number of
decimals are shown according to the settings for the total.
▪Low-battery alarm
Only use original batteries. Original batteries can be ordered at the manufacturer.
The use of unapproved batteries will void the warranty.
•
At the end of the battery’s life-time, the
voltage starts to drop. When the voltage
becomes too low, the battery indicator comes
on. When the battery indicator is on, install a
new and fresh battery as soon as possible.

3.1.2. EXPLANATION OF SETUP-MENU 1 - TOTAL
UNIT
11
This setting is used to select the engineering unit for the indication of the total, the
accumulated total and the pulse output.
When you change the engineering unit , you must recalculate and reprogram the
span for the (accumulated) total. When you recalculate and reprogram the span, the
history for (accumulated) total is not correct anymore, because the (accumulated)
total is not recalculated. For future reference, best practice is to make a note of the
accumulated total before you program the recalculated span.
DECIMALS
12
This setting is used to set the amount of digits behind the decimal point for the
(accumulated) total indication.
SPAN
13
This setting is used to set the span for the total. With the span, the
flowmeter signal is converted to a quantity. The span for Total is based on
the engineering unit (SETUP 11) and the flow rate per second at 20mA
(or max signal). Enter the span with the decimals (decimals are not shown
yet and are set in SETUP 14). The more accurate the span, the more
accurate the functioning of the system will be.
0BExample 1: Calculating the Span.
Assume that the flowmeter generates 20mA at a rate of 652.31 USGAL per hour,
the selected unit is barrels. There are 42 gallons in one barrel; so the rate is
652.31/42 is 15.53119 barrels/hour. This is 0.0043142 barrels/second, which is
the span. Enter for the span: "004314" and for the span decimals "6".
0BExample 2: Calculating the Span.
Assume that the flowmeter generates 20mA at a flow rate of 2,481.3 Liters/minute
and the selected unit is "m3". The rate per second is 2,481.3÷60 is 41.355 L/sec.
This is 0.041355 m3/sec., which is the span.
Enter for the span: "041355" and for the span decimals "6".
When you recalculate and enter a new span, the history for
(accumulated) total is not correct anymore, because the
(accumulated) total is not recalculated. for future reference. Best
practice is to make a note of the accumulated total before you enter
the recalculated span.
DECS SPAN
14
This setting is used to set the amount of digits behind the decimal point for the
span.
3.1.3. EXPLANATION OF SETUP-MENU 2 - FLOW RATE
The settings for total and flow rate are entirely separate. In this way, different engineering units can
be used for each e.g. cubic meters for total and liters for flow rate.
UNIT
21
This setting is used to select the engineering unit for the indication of the flow rate.
Alteration of the engineering unit will have consequences for
operator and setup values, they will not be automatically recalculated
to the value of the new selected unit. The span has to be adapted as
well; the calculation is not done automatically.
TIME
22
This setting is used to set the time unit for the flow rate calculation. Note that the
flow rate is given in engineering unit/time unit, e.g. liters/minute (l/min).
When you change this setting, also recalculate and change the settings for
the analog rate-min and analog rate-max.
DECIMALS
23
This setting is used to set the amount of digits behind the decimal point for the flow
rate indication.

FW_F110A_v1901_02_EN.docx
Page 12
SPAN
24
With the span, the flowmeter signal is converted to a quantity. The span for
flowrate is determined on the basis of the selected measurement unit and
time unit at 20mA (or maximum signal). Enter the span in whole numbers
(decimals are set with SETUP 25).
The more accurate the span, the more accurate the functioning of the
system will be:
Example 1: Calculating the Span
Assume that the flowmeter generates 20mA at a flowrate of 2,481.3
Liters/minute, the selected unit is "Liters" and time unit "minute". The span
is 2481.3
Enter for SETUP 24: "248130" and for SETUP 25 - decimals span "2".
Example 2: Calculating the Span
Assume that the flowmeter generates 20mA at a rate of 652.31 USGAL
per hour, the selected unit is USG and the time unit is minute. The span is
652.31 / 60 minutes is 10.87183 (GPM).
Enter for SETUP 24: "108718" and for SETUP 25 "4".
DECS SPAN
25
This setting is used to set the amount of digits behind the decimal point for the
span.
3.1.4. EXPLANATION OF SETUP-MENU 3 - DISPLAY
FUNCTION
31
This setting can be set to display total or rate.
•When 'total' is selected, simultaneously, total is shown with the large
digits and flow rate with the smaller digits. When SELECT is pressed,
the accumulated total is shown temporarily.
•When 'rate' is selected, only flow rate will be shown with the large
digits together with its measuring unit. When SELECT is pressed, the
total and the accumulated total are shown temporarily.
LIGHT
32
The backlight brightness can be adjusted from 0% (off) to 100% (full
brightness) in steps of 20%.
When the F110-A is only loop powered, the backlight is disabled. An
external power supply is required to supply the backlight.
3.1.5. EXPLANATION OF SETUP-MENU 4 - POWER MANAGEMENT
When used with the internal battery option (type PB/PC), the user can expect reliable measurement
over a long period of time. The F110-A has several smart power management functions to extend
the battery life time significantly. Two of these functions can be set.
LCD NEW

The calculation of the display-information influences the power
consumption significantly. When the application does not require a fast
display refresh rate, it is strongly advised to select a slow refresh rate.
Please understand that NO information will be lost; every pulse will be
counted and the output signals will be generated in the normal way.
At a key press, the display refresh rate will switch to FAST for 30
seconds. When 'OFF' is selected, the display goes off after 30 seconds
after the last key press. The display temporarily comes on after a key
press.
Example battery life-time with a coil pick-up:
•1kHz pulse and FAST update: about 2 years;
•1kHz pulse and 1 sec update: about 5 years.
BATTERY MODE
42
The F110-A has two modes: operational or shelf.
After "shelf" has been selected, the F110-A can be stored for several years; it will
not process the sensor signal; the display is switched off but all settings and totals
are stored. In this mode, power consumption is extremely low.
To wake up the F110-A again, press the SELECT/key two times.

3.1.6. EXPLANATION OF SETUP-MENU 5 - FLOWMETER
FORMULA
51
The F110-A can process the (0)4-20mA signal in two ways:
Interpolation or Square root:
•Interpolation: the signal is processed linear: R = S x I
•Square root: for differential pressure: R = S √I
where:
R= Rate: the calculated flow rate
S= Span: the maximum flow rate at 20mA. The span is programmed with
setting 24 for flow rate and with setting 13 for total.
I= Input: the scaled analog value; in these formulas value 0 (zero) for
(0)4mA and value 1 (one) for 20mA.
FILTER
52
The analog output signal of a sensor represents the actual temperature.
This signal is measured several times a second. The value measured is a
"snap-shot" of the real temperature as it will be fluctuating.
With the help of this digital filter a stable and accurate reading can be
obtained while the filter level can be set to a desired value.
The filter principal is based on three input values: the filter level (01-99),
the last measured analog value and the last average value. The higher
the filter level, the longer the response time on a value change will be.
CUT-OFF
53
To ignore e.g. leakage of the flow or vibration, a low-flow cut-off can be
set as percentage over the full range of 16mA (or 20mA / 10V). When the
analog value is less than the programmed percentage, with this setting,
the flow rate will be set to zero. The cut-off value can be programmed is
the range 0.0 - 99.9%.

CALIB-LO
54
This setting is used to calibrate the input value for (0)4mA as the signal
from the flowmeter might not be exact 4.0 mA (or 0.0 mA) at flow rate
zero. This function will measure the real output value at flow zero.
Be very sure that the offered signal is correct before the calibration
is executed as this function has major influences on the accuracy of
the system!
After pressing PROG, three settings can be selected:
▪CALIB: with this setting, the input will be calibrated with the actual
"(0)4mA" value. After pressing enter, CAL SET will be shown as soon
as the calibration is completed. From that moment, the analog value
must be more than the calibrated value before the signal will be
processed.
▪DEFAULT: with this setting, the manufactures value is re-installed.
▪CAL SET: to select the last calibrated value.
CALIB-HI
55
This setting is used to calibrate the input value for 20mA as the signal
from the flowmeter might not be exact 20.0 mA at maximum flow rate.
This function will measure the real output value at maximum flow rate.
Be very sure that the offered signal is correct before the calibration
is executed as this function has major influences on the accuracy of
the system!
After pressing PROG, three settings can be selected:
▪CALIB: with this setting, the input will be calibrated with the actual
"20mA" value. After pressing enter, CAL SET will be shown as soon
as the calibration is completed. From that moment, the analog value
must be less than the calibrated value for a reliable measurement.
▪DEFAULT: with this setting, the manufactures value is re-installed.
▪CAL SET: to select the last calibrated value.

3.1.7. EXPLANATION OF SETUP MENU 6 - ANALOG
A linear 4-20mA signal (option AB: 0-20mA or option AU: 0-10V) output signal is generated that represents the flow rate.
The settings for the flow rate influence the analog output directly. The relationship between the flow
rate and the analog output is set with the following settings.
OUTPUT
61
If the analog output is not used, select disable to minimize the power
consumption (e.g. save battery life-time).
Option AP: When a power supply is available but the output is disabled, a
3.5mA signal will be generated.
RATE-MIN
62
Enter here the flow rate at which the output should generate the minimum
signal (0)4mA or 0V - in most applications at zero flow. The number of
decimals shown depend upon setup 23. The engineering units/time (e.g.
L/min) are dependent upon setup 21 and 22.
RATE-MAX
63
Enter here the flow rate at which the output should generate the maximum
signal (20mA or 10V) - in most applications at maximum flow. The number
of decimals shown depend upon setup 23. The engineering units/time
(e.g. L/min) are dependent upon setup 21 and 22.
CUT-OFF
64
To ignore leakage of the flow for example, a low flow cut-off can be set as
a percentage of the full range of 16mA, 20mA or 10V.
When the flow is less than the required rate, the current will be the
minimum signal (0)4mA or 0V.
Example: Calculate the cut-off.
Rate-min: 0L/min [4mA], Rate-max: 100 L/min [16mA], Cut-off: 2%
Required rate [L/min]: (rate-max - rate-min)*cut-off: (100-0)*2%=2.0L/min
Output [mA]: rate-min + (rate-max*cut-off): 4+(16*2%)=4.32mA
TUNE-MIN
65
The (0)4mA or 0V value can be tuned precisely with this setting. The
initial minimum analog output value is (0)4mA or 0V. However, this value
might differ slightly due to ambient influences such as temperature for
example.
Before tuning the signal, be sure that the analog signal is not being
used for any application!
After pressing PROG, the current will be about 4mA (0mA or 0V). The
current can be increased / decreased with the arrow keys and is directly
active. Press ENTER to store the new value.
If required, you can program the analog output 'up-side-down'. The
(0)4mA or 0V represents the maximum flow rate and the 20mA or 10V
represents the minimum flow rate.
TUNE-MAX
66
The 20mA or 10V value can be tuned precisely with this setting. The initial
maximum analog output value is 20mA or 10V However, this value might
differ slightly due to ambient influences such as temperature for example.
Before tuning the signal, be sure that the analog signal is not being
used for any application!
After pressing PROG, the current will be about 20mA or 10V. The current
can be increased / decreased with the arrow keys and is directly active.
Press ENTER to store the new value.
If required, you can program the analog output 'up-side-down'. The
(0)4mA or 0V represents the maximum flow rate and the 20mA or 10V
represents the minimum flow rate.
FILTER
67
This setting is used to stabilize the output signal. With the help of this
digital filter a more stable but less actual representation of the flow rate
can be obtained.
The filter principal is based on three input values: the filter level (01-99),
the last calculated flow rate and the last average value. The higher the
filter level, the longer the response time on a value change will be.

3.1.8. EXPLANATION OF SETUP MENU 7 - PULSE
One transistor or mechanic relay output is available as a scaled pulse output according to the total.
WIDTH
71
The pulse width determines the time that the output will be active; in other
words the pulse duration. Value “zero” will disable the pulse output.
The pulse signal always has a 50% duty cycle, hence the minimum time
between the pulses is equal to the pulse width setting. If the frequency
should go out of range –when the flow rate increases for example –an
internal buffer will be used to “store the missed pulses”: As soon as the
flow rate slows down, the buffer will be “emptied”.
It might be that pulses will be missed due to a buffer-overflow, so it is
advised to program this setting within its range!
DECIMALS
72
This setting is used to set the amount of digits behind the decimal point for the
amount.
AMOUNT
73
A pulse will be generated every time a certain quantity is added to the
total. Enter this quantity here while taking the decimals for pulse into
account

4.4. INSTALLING THE HARDWARE
•Electro static discharge does inflict irreparable damage to electronics! Before installing or
opening the F110-A , the installer has to discharge himself by touching a well-grounded
object.
•For reasons of ESD and safety, always ground the metal enclosure properly as indicated,
especially if the unit has been supplied with the 115-230V AC power-supply type PM or
relays type OR. It is the responsibility of the installer to install, connect and test the
Protective Earth connections in accordance with the (inter)national Rules and
Regulations.
•This chapter shows general information regarding the electrical installation of the F110-A .
Chapter 5 gives additional specific information regarding Intrinsically safe installation and
overrules the information given in this chapter.
•When installed in an aluminum enclosure and a potentially explosive atmosphere
requiring apparatus of equipment protection level Ga and Da, the unit must be installed
such that, even in the event of rare incidents, an ignition source due to impact or friction
sparks between the enclosure and iron/steel is excluded.
•Do not blend metal front covers with non-metallic rear covers, vice versa and / or cable
glands. A metal cover on a non-metallic rear cover could lead to ESD. A metal cable
gland in a non-metallic enclosure could invalidate isolation.
4.4.1. GENERAL INSTALLATION GUIDELINES
•The F110-A that came with a power module type PM; 110V-230V AC or type PD/PF with an
option OR (the relays can handle 110V-230V AC) shall be connected to the Protective Earth (PE)
stud which is installed in the metal back panel. The metal front panel is connected to the
Protective Earth by the mounting screws and serrated washers.
•For V AC applications, the terminal 00 shall not be connected to avoid earth loops.
For V DC applications, the terminal 00 shall be connected to the common (do NOT use for PE).
•The wire screens (shield) are meant to prevent electromagnetic interference and shall be,
galvanic isolated, connected to the common ground terminals that belong to the specific sensor
connection. The wire screens shall be terminated at one side to prevent wire loops. Inside of the
Fluidwell unit, the different common ground terminals are connected to each other. It is advised,
as illustrated, to terminate the wire screens in the vicinity of the sensor and to insulated the wire
screen with a shrink tube at the Fluidwell unit side.
•Separate cable glands with effective IP67 / TYPE 4(X) seals for all wires.
•Unused cable entries: make sure that you fit IP67 / TYPE 4(X) plugs to maintain rating.
•A reliable ground connection for both the sensor, and if applicable, for the metal enclosure
(above).
•An effective screened cable for the input signal, and grounding of its screen to the “┴ “ terminal or
at the sensor itself, whichever is appropriate to the application.

FW_F110A_v1901_02_EN.docx
Page 20
4.4.2. PROTECTIVE EARTH (PE) CONNECTIONS
Inside the unit, different types of bonding and earthing are used. The common ground is mostly used
for termination of the wire shields; the Protective Earth (PE) is used for electrical safety.
For externally powered installations, route the Protective Earth (PE) grounding conductor into the
enclosure together with the incoming power conductors.
Risk of damage to equipment!
Be very careful when connecting terminal 00 / GND to Protective Earth (PE).
This terminal is internally connected to the common ground of the system and (especially
when multiple power supplies are connected) the PE connection can cause ground loop
currents that could damage the equipment.
Metal enclosure
When the F110-A is supplied with a metal enclosure (aluminum or stainless steel), the enclosure
must be grounded in accordance with national and local electrical codes.
To ground the field mounted unit, the PE conductor must be connected to the PE stud which is
located in the metal back cover, as indicated in the image below. To connect the conductor, a screw
(M4 x 6mm) with a serrated washer, a terminal and a washer is used (torque: 2 Nm). The metal front
cover is connected to the Protective Earth by the mounting screws with serrated washers.
To ground the panel mounted unit, the PE conductor must be connected to the metal front cover
through one of the four mounting screws. For this purpose, an additional nut, terminal and washer is
supplied.
Field mounted
Panel mounted
Front cover
Fig. 7: Protective Earth (PE) connections on metal enclosure
Plastic enclosure
When the F110-A is supplied with a non-metal enclosure (e.g. plastic), the field mount enclosure
meets the requirements of class 2 (double insulated). Therefore any incoming PE conductor can be
terminated with an insulating end cap.
When the F110-A is panel mounted, the installation class and protective earth requirements depend
on the panel or type of cabinet.
