3010 Flow Transmitter
Section 1 Introduction
The first section of the 3010 Flow Transmitter instruction
manual provides a general introduction to the instrument. It
includes a brief discussion of the organization of the manual, an
overall description of the flow transmitter and ultrasonic level
sensor (USLS), and technical specifications.
1.1 Manual Organization The purpose of this manual is to provide the information nec-
essary to program, operate, maintain, and service the 3010 Flow
Transmitter. To accomplish this, the manual is organized into
five sections and an appendix. This first section is a general
introduction to the flow transmitter. The second section contains
information on operation, programming, and some examples of
programming for specific objectives. The third section provides
installation instructions. The fourth section describes available
options and their uses. The fifth section contains maintenance
information and servicing tips to assist you in correcting
problems that may occur. Appendix A contains lists of
replacement parts and accessories.
1.2 Description The 3010, shown in Figure 1-1, uses ultrasonic level mea-
surement. You normally use the flow transmitter with some type
of primary measuring device to measure flow rate in an open
channel. The 3010 uses level-to-flow rate conversions derived
from a stored equation, covering the majority of open channel
flow measurement situations. If needed, you can enter the coeffi-
cients and powers of the flow equation. However, you can use
most standard weirs and flumes without the need for the
equation. A 6-digit LCD (Liquid Crystal Display) prompts you
through setup, displays the choices for the current programming
step, and displays level and/or flow rate.

1.3 Ultrasonic Level
Sensor
The Ultrasonic Level Sensor, or USLS, shown in Figure 1-2, mea-
sures liquid level without contacting the flow stream. The USLS
consists of an ultrasonic transducer and associated electronics
mounted in a housing, and a shielded cable that connects the
level sensor to the flow transmitter. This cable lets you suspend
the level sensor by the cable alone over a flow stream in tem-
porary installations. For more permanent installations, a
mounting bracket is available to attach the ultrasonic level
sensor securely to the mounting surface. The level sensor is pro-
vided with a 50-foot cable (15.2 meters). For distances greater
than 50 feet, you must use the Quick-Disconnect Box (a type of
splice box) with extension cables. The maximum distance
between the flow transmitter and the level sensor is 1,000 feet
(304.8 meters).
The USLS mounts over the flow stream, and periodically
transmits an ultrasonic pulse to the surface of the stream. The
water surface reflects the echo of the pulse back from the stream
to the level sensor. The elapsed time between pulse and return
echo is proportional to the distance from the level sensor to the
liquid surface. The 3010 uses this time/distance relationship and
a referenced “zero” point in the flow stream to calculate liquid
level. Then, by applying values specific for the primary device in
use, the 3010 calculates flow rate from the measured level. The
USLS has a temperature probe built into its housing to measure

ambient air temperature. The 3010 uses this temperature mea-
surement to compensate for inaccuracies in ultrasonic mea-
surement caused by changes in the air temperature between the
transducer and the flow stream.

1.3.1 SETUP Step The 3010 has a special feature to help you correctly align the
ultrasonic level sensor. This Setup step lets you orient the ultra-
sonic level sensor over the flow stream while an assistant
watches the flow transmitter's display.
The number on the left represents the strength of the sensor’s
return signal, or gain. The number on the right indicates how
much noise is in the return signal due to surface roughness, etc.
(the higher the number, the less noise is present). As long as the
number on the left side of the display is increasing, the sensor is
approaching optimal alignment. When the Setup number
reaches the highest reading, the level sensor is in proper
alignment. If you continue to adjust the level sensor and the
number displayed begins to fall, you have gone past the optimal
alignment.
1.3.2 Labels The 3010 comes with a set of adhesive labels to permit the
display and the mechanical totalizer to express greater values
than the number of digits available on the display. Where
extremely large flow volumes are involved, you can add trailing
zeroes to the display to make more meaningful numbers. To

3010 Flow Transmitter
Section 2 Programming
The following section explains how to program the flow trans-
mitter. There are also sections on the operating theory, control
and indicator descriptions, setup procedures, and programming
examples.
2.1 Operating Theory When measuring flow rate, the 3010 normally uses a primary
measuring device (weir or flume) or other open channel flow
arrangement, where a known relationship exists between level
and flow rate. The level measuring device is an Ultrasonic Level
Sensor that measures the liquid level in the flow stream. The
flow transmitter electronically converts the level reading into a
properly scaled flow rate value. The flow transmitter also pro-
vides standard flow-related output signals to be used for:
• Flow-paced wastewater sampling.
• Recording flow rate information on an external
printer/plotter, circular chart recorder, or other external
serial device
• Connection to a 4 - 20 mA compatible device
• Tripping remote high and low alarm relays
The flow transmitter contains microprocessor-controlled cir-
cuitry to calculate level and flow rates from the signals produced
by the level sensor. It stores programming instructions and
operates the display. A backlit alphanumeric liquid crystal
display (LCD) shows level and flow rate information. The display
also prompts programming of the flow transmitter during initial
setup or subsequent changes. Auxiliary equipment used with the
3010 connects to the terminal blocks on the printed circuit board
in the bottom section of the flow transmitter case.
2.1.1 Ultrasonic Level
Sensor Theory and
Applications
The Ultrasonic Level Sensor (USLS) is mounted over the flow
stream. It measures liquid level by emitting an ultrasonic pulse
and then measuring the time it takes for the echo to return from
the surface of the liquid. The USLS consists of an enclosure with
a single transducer acting both as the pulse transmitter and the
echo receiver. Since the speed of the pulse through the air varies
with temperature, the level sensor has temperature compen-
sation built in. The microprocessor program automatically com-
pensates for speed-of-sound changes caused by air temperature
changes.
Transducer Operation – The USLS emits a strong ultrasonic
pulse several times a second. After transmitting the pulse, the
flow transmitter electronically switches the level sensor trans-
ducer into a receiver or microphone, ready to receive or hear the

3010 Flow Transmitter
Section 2 Programming
2-2
echo reflected back from the flow stream. The transducer con-
verts the echo sound into a small pulse that the circuitry in the
flow transmitter amplifies and detects to produce an “echo
received” signal. The time between the transmitted pulse and
received echo is proportional to the distance between the trans-
ducer and the surface of the stream. The flow transmitter uses
this distance to determine the liquid level in the stream.
Validity Tests and Error Display – The flow transmitter sub-
jects the measured level to several validity tests. If the unit
cannot obtain a valid level, it repeats the process. Meanwhile, the
last good level reading will continue to appear on the display. If,
after approximately four minutes, the flow transmitter cannot
obtain a valid reading, the 3010 will show EE 80 on the display.
In such instances, it may be necessary to realign the level sensor
or check the operation of the flow transmitter.
Ambient Air Temperature Factor – The 3010 uses an ultra-
sonic distance measurement technique based on the speed of
sound in air. Since the speed of sound in air varies with temper-
ature (approximately 1% for 10× of variation), you must provide
compensation. The level sensor uses the air temperature sensor
and microprocessor-based compensation to accurately account
for air temperature variations. See also Section 2.1.2.
Return Echo Amplifier Compensation – The signal strength
of the returned echo depends on several factors including the dis-
tance from the transducer to the water surface. For every
21/2-foot increase in the distance between the transducer and the
liquid surface, the strength of the returned echo decreases by
half, so designers must compensate the gain of the return echo
amplifier for distance. As the distance increases between the
transducer and the liquid surface, the gain of the echo amplifier
increases with time to compensate for the decreasing signal
strength of the echo. This type of amplifier, whose gain character-
istic is based on a repeating time interval, is referred to as a
“ramp gain” amplifier.
2.1.2 Error Factors Affecting
Performance
Several external factors can influence both the initial pulse and
reflected sound wave, causing the ultrasonic measurement
system to produce errors. These factors fall broadly into two
classes.
Velocity Errors – These errors result when the flow trans-
mitter is unable to accurately calculate the velocity of sound.
They are “proportional” errors, in that the degree of error
increases as the distance between the level sensor and the
surface of the flow stream increases.
Echo Detection Errors – These errors arise from problems the
flow transmitter can have measuring the time between trans-
mitting the ultrasonic pulse and receiving the echo. Anything
that absorbs sound can cause these errors. This makes the echo
amplifier detect the returned signal either earlier or later than
intended in the design of the “ramp gain” amplifier. Errors of this

3010 Flow Transmitter
Section 2 Programming
2-3
sort will generally be of an “absolute” nature; the distance
between the transducer and the water will not affect them to any
great extent.
2.1.3 Error Factors and Flow
Compensation
Following are specific factors affecting the accuracy of the 3010
with the measures used for compensation of the more significant
factors.
Barometric Pressure – The velocity of sound is essentially
independent of barometric pressure. Changes in barometric
pressure provide no significant cause of error.
Beam Angle – The flow transmitter must only respond to sur-
faces within a specific area. The transducer can only “see” items
inside a “cone” whose apex is the ultrasonic transducer. The
beam angle is the angle across this cone. If the beam angle is too
wide, the flow transmitter will detect unwanted surfaces, such as
the walls of the channel. If the beam angle is too narrow, setup of
the installation is difficult and the flow transmitter may never
detect an echo.
Humidity – The velocity of sound varies only slightly with
humidity (maximum 0.35% at 68°F). Because the effect is small,
the 3010 does not provide compensation for humidity. Humidity,
however, does have an effect on the reduction of the echo. Under
extreme humidity conditions, the reduction of the sound wave
may be inconsistent with the characteristics of the “ramp gain”
amplifier, causing an echo detection error.
Noise – Background noise can interfere with the operation of the
flow transmitter. The unit must filter out this noise, or it may
trigger on the noise rather than the returned echo. The 3010 uses
a tuned circuit to filter out unwanted noise outside the operating
frequency. Noise in the operating frequency range (49 kHz) can
render the system unstable. The unit uses software algorithms to
eliminate most sporadic noise pulses occurring within the flow
transmitter's operating frequency range.
Surface Objects – Objects or foam floating on the surface of the
flow stream can absorb or weaken the ultrasonic pulse. If the
foam or material reduce the pulses enough, the unit will lose the
echo altogether. In less severe cases, there may be an echo
detection error.
Temperature – The velocity of sound at a given temperature
may be approximated by the following equation:
Where velocity is in feet per second and temperature is in
degrees F. Temperature changes have a significant effect on the
velocity of sound (approximately 7% between 32°F and 104°F).
This variable is significant enough to require compensation. Con-
sequently, the 3010 provides temperature compensation. There is
a temperature sensor embedded in the level sensor. However, the
temperature of the level sensor and air may not be exactly the
same, and the temperature sensor cannot measure temperature

perfectly. As a result, the equations used to calculate the velocity
of sound in air are approximations, including the equation shown
above.
Waves – Waves or extreme turbulence on the surface of the flow
stream can deflect the sound energy so it does not return to the
transducer. Waves may also make the sound return to the trans-
ducer by an indirect path. In the first case, the flow transmitter
will not receive an echo. In the second case, the additional time
lapse will cause an echo error that will appear as an incorrect
level reading. The 3010 has a software algorithm to reject occa-
sional readings that deviate substantially from normal. However,
if the waves are severe, the flow transmitter will not function and
will indicate a “no echo” condition.
Wavelength – You can determine the wavelength of sound by
dividing the velocity of the sound by the frequency. The frequency
of the 3010 is about 49 kHz. You can find the length of a 49 kHz
sound wave by dividing 1,125 feet /second by 49,000, which is
0.02296 feet or 0.276 inches.
Wave (Echo) Detect Error – Under ideal conditions the trans-
ducer can detect the same wave front of the returning echo.
However, any noise or abnormal attenuation may cause some
transducers to detect an earlier or a later wave. When the atten-
uation of the returned echo does not match the gain slope of the
amplifier, the circuit will eventually detect a different cycle of the
returned echo as the distance changes. The impact of this
wave-detect error is determined by the wavelength.
Wind – Wind can blow the sound away or significantly reduce
the intensity of the returned echo. Narrow beam angles, advanta-
geous for measuring small flow streams, are a disadvantage in
this situation. Likewise, greater distances to the surface of the
flow stream are more affected by wind.
Note
You can reduce the effects of these factors substantially by fol-
lowing the suggestions for ultrasonic level sensor installation
found in Section 3.7.

.(DECIMAL) – Use this key with the number keys when
entering numeric values into the program.
ENTER/PROGRAM STEP – Pressing this key will allow you to
enter changes made to the program into memory. To access the
program, first press one of the yellow Function Keys (See below.)
Pressing one of the Function Keys stops the program and allows
you to make changes. After the you make the change and it
appears on the display, pressing ENTER/PROGRAM STEP will
enter the change into memory. It is also possible to step through
the program retained in memory by pressing this key. The
number of the program step will appear on the left side of the
display and the number of the current selection (or value
entered) will appear next to it.
NUMBER KEYS – Use the number keys to enter numeric
values into the program. You can also use them to make a
selection from the options displayed on the label.
+-(PLUS/MINUS) – Use this key to enter positive or negative
numbers when programming an equation.
FUNCTION KEYS – The yellow keys let you enter the program
of the 3010 at specific steps so you can change selections or
numerical values. These keys govern specific programming steps,
and will be described elsewhere. Refer to Section 2.3.3 for the
detailed descriptions of the Function Keys.
2.2.2 Display The flow transmitter display shows programming choices. After
you complete programming and installation, the display shows
the present flow rate and/or level. There are three operating
modes for the display: level, flow rate, or an alternation between
the two. You can see the display through the window when the
door is closed. The display is a 6- digit, 7-segment liquid crystal.
The letter H on the left side of the display indicates level (or
Head). For better visibility in low light conditions, the LCD is
lighted.
2.2.3 Power Failures If there is a power failure, the LCD will blank and the flow trans-
mitter will stop operating. Momentary power failures (less than
three seconds) should not affect the operation of the unit, as
power stored in the filters will provide some carryover for a brief
period of time. However, if power is off long enough for the
display to blank, flow pulses to the sampler will stop, as will the
mechanical totalizer and the totalizer signal sent to the external
plotter, which will be reset. The unit will not be able to recognize
changes in level during the time power is off. However, memory
will retain the program selections made during setup and when
power is restored, you won't need to reprogram the flow trans-
mitter.

2.3 Programming Enter program quantities and control certain functions through
the keypad. The number of the selected entry appears on the
display. The display also indicates operational status, and guides
you through the programming sequence by showing the step pro-
grammed. Each time you press a key, the unit will beep.
Refer to Figure 2-1 for a flowchart showing programming. At the
back of this manual is a worksheet on which you may write
program selections.
2.3.1 Programming
Overview
Remember that the flow transmitter always has a program in it,
stored in memory, even if it is only the default program installed
at the factory. To program the 3010, press the yellow FUNCTION
KEYS. The display will show the step number on the left and the
number of the choice currently selected (or the numerical value
entered for steps requiring a value) on the right. You will not
need to program all steps. For example, if there is no remote
plotter, you would skip Steps 11 to 15, all involved with operation
of the plotter.
The program steps are printed on the flow transmitter label, and
normally programming proceeds in a logical manner, starting
with Step 1, which sets level in feet or meters. Step 2 selects the
primary measuring device. Then you select maximum head, flow
rate at maximum head, and totalizer scaling. If you aren't using
any other equipment with the 3010, you need to program only
Step 16 PROGRAM OPERATION, and 18 LEVEL ADJUST. If
you are installing the unit for the first time, use the SETUP key
to optimize transducer alignment. Then you use the LEVEL
ADJUST key to calibrate the level sensor.
You only make selections in Steps 10 through 15 and Step 17
when the flow transmitter is connected with associated
equipment. Step 10 governs the relationship between the flow
transmitter and a sampler. Steps 11 - 15 control the output to an
Isco High-Low Alarm Relay Box (a device to trigger other
equipment when flow exceeds or falls below a pre-set value), or
an external serial device.
Step 17 determines the operation of the 4-20 mA current loop
output. Examples of devices that operate from the 4-20 mA
current loop are the Isco Model 2410 Circular Chart Recorder
(discontinued) and process equipment, such as a chlorinator.
After you have installed and programmed the flow transmitter
the first time, it is not necessary to completely reprogram the
unit to enter any changes. Instead, simply select the yellow
function key where you want to make a change and press
ENTER until the desired step is reached; then enter the change.
Automatic Program Advance – After you press ENTER, the
display will automatically advance to the next step and show the
current choice or value entered for that step; the process con-
tinues until you have made selections for all steps necessary to
complete the step sequence you have selected, or you press the
CLEAR ENTRY key twice to exit the program.
