BEFORE OPERATING THE D902/3
Important Notice!
The D902/3 flow meter is equipped with a Lead Acid Gel
Cell battery. This battery will require charging before initial
operation.
Apply AC power, utilizing the enclosed line power cord, to
the D902/3 for a period of 16-24 hours prior to using the
product for the first time. The line cord connects to the
socket connection located on the side of the enclosure.
Do not allow the battery to completely discharge.
(Discharging the battery to the point where the LOW
BATTERY indicator illuminates will not damage the
battery. Allowing the battery to stay discharged for long
periods of time can degrade the storage capacity of the
battery.) When not in use, continually charge the battery
by keeping it plugged into line power. The D902/3 has an
integral charging circuit that prevents overcharging. The
instrument can be permanently connected to AC line power
without damaging the flow meter or the battery.

PART 1 - INTRODUCTION
General
Application Versatility
The D902/3 ultrasonic flow meter is designed to measure
the fluid velocity of liquid within closed conduit. The
transducers are a non-contacting, clamp-on type, which
will provide benefits of non-fouling operation and ease of
installation.
The flow meter operates by transmitting an ultrasonic
sound from its transmitting transducer through the pipe
wall into the flowing liquid. The sound will be reflected by
suspended particles or bubbles within the liquid and
recorded by the receiving transducer. A frequency shift
(Doppler effect) will occur that is directly related to the
speed of the moving particle or bubble. This shift in
frequency is interpreted by the instrument and converted to
various user defined measuring units.
A unique feature of this product is that it employs a
proprietary digital filtering system and recognition circuit.
This feature allows the instrument to measure fluid
velocities of clean liquids if the transducers are mounted
downstream from a 90° elbow. The non-symmetrical
hydraulic turbulence which occurs downstream of an elbow
is captured, linearized and can be displayed as liquid
velocity and volume. This capability is not available in
conventional Doppler technology.
The D902/3 flow meter can be successfully applied on a
wide range of metering applications. The simple to program
transmitter allows the standard product to be used on pipe
sizes ranging from 1 - 120 inch (25 - 3048 mm) pipe I.D.
With the small pipe transducer option, the pipe size range
is 0.25 - 1 inch (6 - 25 mm). A variety of liquid applications
can be accommodated: raw sewage, reclaimed water,
cooling water, river water, plant effluent, mining slurries,
sludge, etc. Because the transducers are non-contacting
and have no moving parts, the flow meter is not affected
by system pressure, fouling or wear. Standard transducers
are rated to 250 °F (121 °C). Optional high temperature
transducers are rated to operate to 400 °F (204 °C).

User Safety
Battery Backup
Product Identification
The D902/3 employs modular construction and provides
electrical safety for the operator. The display face contains
voltages no greater than 9 Vdc and the metal work is
electrically connected to earth ground. All user connections
are made through sealed, bulk-head plugs located on the
side of the D902/3 enclosure.
A rechargeable nickel-cadmium battery on the back of the
display board retains all user-entered configuration values
in memory for several years (at 25 °C), even if power is
lost or turned off. The ten year battery is continually trickle
charged whenever line power is applied. A completely
discharged battery recharges fully after 48 hours of
instrument operation.
The serial number and complete model number of the
D902/3 are located on the inside of the transmitter cover.
Should technical assistance be required, please provide
the Dynasonics Customer Service Department with this
information.

Considerations
Step A -
Mounting
Locations
CASE 1:
Figure 4
The transducers that are utilized by the D902/3 contain
piezoelectric crystals for transmitting and receiving
ultrasonic sound energy through the pipe wall.
The transducers can be mounted in three different
configurations. The selection of the proper configuration is
dependent on the characteristics of the liquid to be
measured.
The three liquid characteristics, which will affect mounting
location and orientation, are as follows:
CASE 1: Liquid that contains 25 to 10,000 PPM (1%) of
30 micron or larger suspended solids or aeration.
CASE 2: Liquid that contains greater than 10,000 PPM
(1%) of 30 micron or larger suspended solids or aeration.
CASE 3: Liquid that contains fewer than 25 PPM of 30
micron or larger suspended solids or aeration and
suspended solids and aeration content which is smaller
than 30 microns.
Liquid that contains 25 to 10,000 PPM (1%) of 30
micron or larger suspended solids or aeration.
Select a transducer mounting location with adequate
straight runs of pipe, both upstream and downstream, to
achieve stable readings. Examples of minimum upstream
and downstream requirements are included in Table 1.
Mount the transducers 180° apart and facing each other on
the pipe. If the pipe is horizontal, the preferred mounting
orientation is 3 and 9 o’clock, with 12 o’clock being the top
of the pipe. Orientation on vertical pipes does not matter.
See Figure 4.

The D902/3 system will provide repeatable measurements on piping systems
that do not meet these requirements, but the accuracy of these readings may
be influenced to various degrees.
Rev. 10/08 - 11 - D902/3
PART 2 - TRANSDUCER INSTALLATION
CASE 2:
Liquid that contains greater than 10,000 PPM (1%) of
30 micron or greater suspended solids or aeration.
The mounting location and straight pipe requirements for
CASE 2 liquid characteristics are the same as those
described in CASE 1. The difference will be in the location
of the transducers on the pipe. As the discontinuities
(suspended solids or aeration) reach a level of
approximately 1% or 10,000 PPM, sound can no longer be
reliably transmitted through the liquid as it has a tendency
to scatter and absorb into the high concentration of
discontinuity. To compensate for this, the D902/3
transducers can be located on the same region of the pipe.
In a horizontal pipe, mount the transducers at 2 o’clock
and 4 o’clock positions. (Assuming 12 o’clock as the top of
the pipe.) See Figure 5.

CASE 3:

Liquid that contains fewer than 25 PPM of 30 micron or
larger suspended solids or aeration. Or, liquid that
contains solids or aeration which is smaller than 30
microns.
The transducers will be mounted 1 to 3 pipe diameters
downstream from a 90° elbow. The orientation of the
transducers on the pipe will be 180° apart and facing each
other and 90° out of the plane of the elbow. See Figure 6
on page 13.

Figure 6
Before the transducer heads are bonded to the pipe
surface, an area slightly larger than the flat surface of the
transducer must be cleaned to bare metal on the pipe.
(Plastic pipes do not require preparation beyond removal
of paint.) Remove all scale, rust and paint. Thoroughly
dry and degrease the mounting surfaces.
NOTE: Small pits in the piping surface typically do not
significantly impact ultrasonic transmission or signal
reception.
After selecting the applicable mounting location and
preparing the piping surface as detailed in Steps A and B,
the transducer can be mounted to the pipe.
NOTE: High Temperature transducer installations require
specialized mounting hardware and instructions. For
drawings detailing installation of this option, contact
the factory.
Steps A and B, Mounting Locations and Pipe Preparation
sections of this manual apply to the High Temperature
option. Reference these sections as required.
Rev. 10/08 - 13 - D902/3
PART 2 - TRANSDUCER INSTALLATION
To assure an acoustically conductive path between the
transducer face and the prepared piping surface, a
coupling compound is employed. Enclosed with the
D902/3 system is a tube of Dow Corning 111, silicone
grease. This couplant is satisfactory for temporarily
mounting the transducers to the pipe. If the installation is
long-term (more than a few days), Dynasonics
recommends utilizing a silicone-based RTV such as Dow
Corning RTV-732. If alternate couplants are utilized, the
grease chosen must be rated to not flow at the
temperature of the pipe.
1. Wrap the elastic strap (enclosed) around the pipe in the
area where the transducers are to be mounted. Mount
the strap snuggly, but leave the strap just loose enough
to allow the transducers to be placed underneath.
2. Spread an even layer of coupling compound,
approximately 1/8 inch (3 mm) thick, to the prepared
transducer mounting areas of the pipe. Utilize Dow 111
for temporary mounting or Dow 732 for permanent
mounting.
3. Spread an even layer of the coupling compound,
approximately 1/8 inch (3 mm) thick, to the flat face of
the two transducers.
FLOW
DIRECTION
Figure 7
Rev. 10/08 - 14 - D902/3
4. Place each transducer under the strap with the flat face
positioned towards the pipe. The notch on the back of
the transducer will provide a mounting surface for the
strap. The transducer cables must be facing in the
same direction for proper operation. See Figure 7.
NOTE: Large pipes may require two people for this
procedure.
5. Tighten the strap tight enough to hold the transducers
in place, but not so tight that all of the couplant
squeezes out of the gap between the transducer face
and pipe. Ensure that the transducers are squarely
aligned on the pipe.
PART 2 - TRANSDUCER INSTALLATION
6. Route the transducer cable back to the transmitter
mounting area avoiding high voltage cable trays and
conduits. Do not attempt to add additional cable to the
factory supplied transducer cable. The D902/3
processes very small signals, so the cable shield must
be continuous.
7. If the transducers are to be permanently mounted using
Dow 732, the RTV must be completely cured
proceeding to Instrument Startup. Ensure that no
relative motion between the transducer and pipe occurs
during the 24 hour curing process. If Dow 111 grease
was used for temporary operation of the D902/3
system, proceed with the Instrument Startup procedures.

Figure 8
The D902/3 enclosure should be located in an area that is
convenient for observation of the LCD readout and keypad
operations. To prolong the life of the keypad and controls,
the enclosure cover should be left closed when the unit is
unattended.
Place the D902/3 transmitter in a location that is:
♦ Where little vibration exists.
♦ Protected from falling corrosive fluids.
♦ Within ambient temperature limits -22 to +160 °F (+30
to +70 °C)
♦ Out of direct sunlight. Direct sunlight may increase
temperatures within the transmitter to above maximum
limit.
Connect the transducer plug to the socket connection
located on the side of the D902/3 enclosure. Refer to
Figure 8. Ensure that tension on the retractable cables
has not pulled either of the transducers out of position on
the pipe. The transducers must be squarely mounted to
achieve greatest accuracy.
NOTE: The transducer cable carries low level signals. Do
not attempt to add additional cable to the factory supplied
transducer cable.

connect the meter to AC line power. Line power is
connected by plugging the enclosed line cord into the
appropriate connector socket located on the side of the
D902/3 enclosure. See Figure 10. Use wiring practices
that conform to local codes (National Electric Code
Handbook in the USA). Use only the standard three wire
connection. The ground terminal grounds the instrument,
which is mandatory for safe operation.
CAUTION: Any other wiring method may be unsafe or
cause improper operation of the instrument.
It is recommended not to run line power with other signal
wires within the same wiring tray or conduit.
NOTE: This instrument requires clean electrical line
power. Do not operate this unit on circuits with noisy
components (i.e. Fluorescent lights, relays, compressors,
variable frequency drives, etc.).

PART 2 - SERVICE AND MAINTENANCE
Battery Care and
Maintenance
The D902/3 flow meter is equipped with a Lead Acid Gel
Cell battery. This battery will require charging before initial
operation. Apply AC power, utilizing the enclosed line
power cord, to the D902/3 for a period of 16-24 hours prior
to using the product for the first time. The line cord
connects to the socket connection located on the side of
the enclosure.
The D902/3’s integral battery provides continuous
operation for up to 8 hours on a full-charge. The battery is
“maintenance free”, but it still requires a certain amount of
attention to prolong its useful life. To obtain the greatest
capacity and longevity from the battery, the following
practices are recommended:
• Do not allow the battery to completely discharge.
(Discharging the battery to the point where the LOW
BATTERY indicator illuminates will not damage the
battery. Allowing the battery to stay discharged for long
periods of time can degrade the storage capacity of the
battery.) When not in use, continually charge the
battery by keeping it plugged into line power. The
D902/3 battery management circuitry will not allow the
battery to become “over-charged”.
NOTE: The D902/3 will automatically enter a low power
consumption mode approximately 1-1/2 minutes after the
LOW BATTERY indicator illuminates. This circuit prevents
excessive discharge of the internal battery.
• If the D902/3 is stored for prolonged periods of time,
monthly charging is recommended.
• If the D902/3 is stored for prolonged periods of time,
store at a temperature below 70 ºF (21 ºC).
The CHARGING indicator will always be illuminated when
the D902/3 is connected to line power and the flow meter
is turned ON. If the D902/3 is turned OFF and line power
is connected, the CHARGING indicator will illuminate only
when the internal circuit is charging the battery. During
storage, the CHARGING indicator will cycle as necessary.
Rev. 10/08 - 18 - D902/3
PART 2 - SERVICE AND MAINTENANCE
Desiccant Cartridge
The D902/3 is equipped with a DESICCANT CARTRIDGE,
which is located in the face plate of the meter. The
purpose of the cartridge is to absorb the humidity that was
present inside of the enclosure when the product was
manufactured and to absorb moisture that may seep into
the enclosure during field operation. Observing the color
indicator of the DESICCANT CARTRIDGE and replacing it
when it turns PINK will decrease the chance of corrosion
and resulting failure of the internal components of the
D902/3.
Procedure:
1. Obtain a new DESICCANT CARTRIDGE from
Dynasonics (Dynasonics P.N. D005-9909-001).
2. Replace the cartridge in a temperature and humidity
controlled environment. Allow the meter to reach the
same ambient temperature as the area in which the
cartridge will be replaced. (Do not attempt to change
the cartridge if the meter is below the Dew Point
Temperature.)
3. Remove the old cartridge with a 1-3/8" open-end
wrench or appropriate adjustable wrench.
4. Insert the new cartridge and tighten with the wrench.
5. Discard the used cartridge.

PART 3 - STARTUP AND CONFIGURATION
Before Starting the
Instrument
Instrument Startup
Important!
NOTE: The D902/3 flow meter system requires a full
pipe of flowing liquid before a successful startup can be
completed. Do not attempt to make adjustments or
change configurations until both a full pipe and liquid flow
are verified.
NOTE: If Dow 732 RTV was utilized to couple the
transducers to the pipe, the adhesive must fully cure
before power is applied to the instrument. Dow 732
requires 24 hours to cure satisfactorily. If Dow 111 silicone
grease was utilized as a couplant, the curing time is not
required.
Procedure:
1. Verify that all wiring is properly connected and routed.
2. Set the SENSITIVITY Control to -2. This control is
located on the D902/3 front panel.
3. Apply power. The POWER indicator will illuminate.
4. Adjust the SENSITIVITY control so that the right-most
LED on the SIGNAL STRENGTH bar meter just
illuminates or SIGNAL STRENGTH is at least in the
yellow/green region.
NOTE: It is undesirable to adjust the SENSITIVITY control
to a position higher than necessary, as ambient noise can
also be amplified. This noise can cause false readings to
occur.
5. If the pipe is full of a flowing liquid, the READ indicator
will illuminate and the display will begin reading fluid
velocity as FPS (Feet per Second) or MPS (Meters per
Second). It is normal to have low SIGNAL STRENGTH
and FAULT indication at ZERO flow.
6. If a SIGNAL STRENGTH reading in the green portion
of the bar meter or a FLOW ANALYZER indication
could not be obtained, refer to the troubleshooting
section of this manual.

Modes of Operation
Default Configuration
After a successful flow meter installation and startup
(covered in the previous sections of this manual) the
D902/3 can be keypad configured to provide select
engineering unit readings of flow and a scaled 4-20 mA
output. Configuration inputs are made via the keypad and
are stored by the microprocessor. The entries are retained
by the flow meter’s backup battery in the event of power
failure. If fluid velocity readings in FPS or MPS are the
only required measurement, keypad configuration is not
required.
The RUN/ENT key toggles the flow meter between the two
modes of operation.
RUN Mode: This is the primary operating mode of the
flow meter. The meter is in RUN mode when the readout
is displaying flow as velocity (FPS, MPS) or volume (GPM,
LPM, LPS). In RUN mode the outputs are active and
transmitting signals proportional to flow rate.
ENTRY Mode: This mode is used to view or change the
configuration of the flow meter. When the D902/3 ships

(Feet per Second) or MPS (Meters per Second) dependent
on whether the unit is configured as U.S. units or Metric
units. The FULL SCALE input is used by the D902/3
microprocessor to scale the 4-20 mA output and adjust the
resolution of the flow rate display.
Acceptable input range for the FULL SCALE constant is
shown in Table 4.

Totalizer Exponent
Input
The VOL. PULSE key allows the entry of a totalizer
exponent. This feature is useful for accommodating a very
large accumulated flow. The exponent is a “×10” multiplier,
which can be from 0 (no multiplier) to 2 (×100). For
example, to totalize in GAL × 100, a VOL. PULSE value of
2 would be used (10² or 100).
Acceptable input range for the VOL. PULSE constant is
shown in Table 5.

* NOTE: If an entry greater than 2 is attempted, the meter
will display OVER!. If a non-whole number value is attempted,
the meter will display RANGE!. A legitimate value will need to
be entered.
After a VOL. PULSE value is entered, the display will
reflect the unit as 0=10º=×1, 1=10¹=×10 and 2=10²=×100.

Attempting to enter values other than 1, 2 or 3 will result in
an UNDER! or OVER! to be displayed. Non-whole number
values will result in a RANGE! display. A legitimate value
must be entered.
A few factors can influence the readings of the D902/3
flow meter. The CAL entry allows the user to compensate
for flow discrepancies without affecting the factory
calibration. Examples of situations that can cause reading
discrepancies are:
• Operation on liquids with sonic velocity carrying
properties that are different than water. Please refer to
the Fluid Sound Speed correction chart located in the
Appendix of this manual.
Table 7
FPS MPS
GPM LPM
MGD LPS
• Transducers mounted in non-recommended locations.
• Operation on fluids with a large amount of suspended
solids.
By applying a CAL value other than 100%, the factory
calibrated readings will be altered by the percentage
entered. This CAL value will not
output.
For example, if a reading of 175 GPM is displayed and the
known flow rate is 160 GPM, a CAL value of
160 GPM

Totalizer
FLOW ANALYZER
The RESET key is used for generating a system reset or
to reset the accumulated flow. Press the RESET button
from the ENTER Mode. A choice is then made to:
RESET Reset the system
VOL. MULT Press VOL. PULSE to
reset the totalizer to
zero
If the RESET key is pressed again, all configuration
constants will return to default values.
If the VOL. PULSE key is pressed, the accumulated flow
will be erased and the display will return to zero.
In RUN Mode, pressing the decimal point once will
suspend totalizer accumulation. Pressing the decimal
point again will clear the total. Pressing it a third time will
restart the accumulation from zero.
NOTE: In RUN mode, the key presses are processed
and displayed at the interval defined by the DAMP
constant setting. (i.e. If the DAMP constant is set to
10, the key presses will be acknowledged only every
20 seconds.)
The FLOW ANALYZER bar meter indicates the relative
condition of the Doppler signal that is being processed by
the D902/3. When the instrument is utilized on liquids with
suspended solids or aeration, the FLOW ANALYZER will
indicate within the two right segments — an ideal Doppler
condition. When the D902/3 is used to measure cleaner
liquids, the FLOW ANALYZER bar meter will search its
discrete filter banks and adjust to match the particular
liquid parameters that are present. The bar meter will
indicate these changes when they occur. If no segments
are illuminated on the FLOW ANALYZER, the level of
liquid discontinuity or hydraulic turbulence is inadequate
and the transducers will have to be relocated. Typically,
moving the transducers closer to a 90º elbow will provide
adequate liquid conditions.

POSSIBLE CAUSE
• Verify that the battery is charged. Plug
into an AC power source.
• Test the fuse.
• Ensure the terminal block located in the
upper left corner of the main PCB is
secure.
• Verify that ribbon cables between PCBs
are connected.
• Increase the value of the FULL SCALE
constant.
• Verify that fluid velocity is not greater than
20 FPS (6.08 MPS).
• Ensure that the transducers are properly
mounted to the pipe.
• Verify that transducer connections are
correct.
• Ensure that the pipe is full of moving
liquid.
• Increase SENSITIVITY so that right-most
SIGNAL STRENGTH light just comes ON.
• On cleaner liquids, move the transducers
o
closer to a 90
pipe elbow.
• On dirtier liquids, mount the transducers
as described in CASE 3 in Part 2 of this
manual.
• If the pipe has a polyethylene liner, move
the transducers to another area. The liner
may contain an air void at this location.

Stability of flow readings are
unsatisfactory
This procedure requires the
face plate to be removed
from the enclosure.
Erroneous Reading
• If GND connection and pipe are at different
potentials, ground D902/3 to pipe potential.
• If Variable Frequency Drives are being
utilized, verify that the D902/3 obtains a
READ light when the pump is turned OFF.
If possible, increase the carrier frequency
of the drive.
• Increase the DAMP constant from keypad.
• Increase the system time constant by
turning R17 (DAMP) clockwise till readings
are satisfactory.
• Move transducers to a location further from
piping tees, elbows, valves, filters, etc.
• Transducers mounted incorrectly.
• Another local ultrasonic instrument is
operating at about the same frequency
(consult the Dynasonics factory).
The D902/3 display indicates flow, when
true fluid velocity is zero
• Presence of large amounts of suspended
solids or aeration. Use CAL constant to
compensate.
• Sources of radiated interference are
present. Apply appropriate shielding.
• An electrically noisy power supply is
powering the D902/3. Power the meter
with a circuit that does not power motors,
ballasts or switching supplies.
• Verify that residual leakage and flow are
not present (i.e. leaking check valves).
• Verify that SENSITIVITY is not adjusted
too high. With nominal flow running
through the pipe, adjust SENSITIVITY
control till the right-most bar meter light just
comes ON.
