QUICK-START OPERATING INSTRUCTIONS
This manual contains detailed operating instructions for
all aspects of the D77X instrument. The following
condensed instructions are provided to assist the
operator in getting the instrument started up and running
as quickly as possible. This pertains t o basic operation
only. If specific 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.
1. TRANSDUCER LOCATION AND PIPE
PREPARATION
A. Select an appropriate mounting location for the
DT7 transducer probe.
B. The probe should be located on a straight piece of
pipe with a minimum of 10 unobstructed pipe
diameters upstream from the installation point and
a minimum of 5 unobstructed diameters
downstream of the installation point.
Pipe Preparation
and Mounting
C. A 1-1/2” NPT female threaded connection on the
pipe is required for the probe assembly to be
mounted. This connection is typically made by
welding a threaded coupling to the pipe wall or
installing a pipe saddle. The connection should
be mounted perpendicular to the pipe at a radial
location 20-160 degrees from the top of the pipe.
2. TRANSDUCER INSTALLATION
DO NOT remove the cotter pins located at the ends
of the threaded rods. They prevent the probe from
being completely extracted from the insertion fitting
and causing a potentially dangerous condition.
A. Insert the DT7 Transducer Probe tip to the 1/8
pipe I.D. location. The velocity measurement is
made 0.67 inches [17 mm] from the very tip of the
probe. Total insertion depth can be calculated at:
Rev. 12/97 -1- D77X
QUICK-START OPERATING INSTRUCTIONS
Insertion Depth =
(pipe I.D. inches) X 0.125 + 0.67 inches
or
(pipe I.D. mm) X 0.125 + 17 mm
B. Secure the probe insertion distance using the upper
and lower brass jam nuts located on the threaded
rods.
C. Loosen the set screw located in the probe retaining
collar with the enclosed allen wrench.
D. Rotate the probe body till the arrowhead, located
on the top of the probe, is parallel with the pipe and
points down stream in the direction of flow.
E. Lock the probe rotation with the set screw in the
retaining collar.
F. Route the transducer cable back to the transmitter,
avoiding locations near high voltage supply wires.
Transducer connections are made through the left
conduit hole in the bottom of the transmitter.

PART 1 - INTRODUCTION
General
Application Versatility
User Safety
The D77 ultrasonic flow meter is designed to measure the
fluid velocity of liquid within closed conduit. The rugged
insertion probe has no moving parts, is insensitive to
coating buildup and can be accurately positioned at the
precise depth in the pipe required to measure liquid
velocity in a variety of liquid phases. (Conventional,
through the pipe wall, Doppler flow meters are sensitive
to large changes in liquid viscosity and solids content.
The D77 is not sensitive to such changes.)
The flow meter operates by transmitting an ultrasonic
sound from its transmitting piezoelectric crystal into the
flowing liquid. The sound will be reflected by suspended
particles or bubbles within the liquid and recorded by the
receiving piezoelectric crystal. 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.
The D77 flow meter can be successfully applied on a wide
range of metering applications. The simple to program
transmitter allows standard D77 to be used on pipe sizes
ranging from 1.5 - 120 inch [ 38 - 3048 mm ] pipe I.D. A
variety of liquid applications can be accommodated: raw
sewage, reclaimed water, cooling water, river water, plant
effluent, mining slurries, sludge, etc. The D77 is ideal for
measuring through thick walled pipes. The D77C is
designed specifically for Crude Oil measurements.
Because the transducers are encapsulated in a resilient
PVDF plastic shell and have no moving parts (in the
traditional sense), the flow meter is very resistant to
fouling and wear. Standard transducers are rated to
180?F [82?C].
The D77 employs modular construction and provides
electrical safety for the operator. The display face
contains voltages no greater than 15 Vdc and the
enclosure is made from non-conductive fiberglass. All
user connections are made through conduit hole located
on the under side of the D77 enclosure.

Rev. 12/97 -10- D77X
PART 2 - TRANSDUCER INSTALLATION
Transducer Mounting
Considerations
Step A - Mounting
Locations
The DT7 insertion transducer that is utilized by the D77
contains piezo electric crystals for transmitting and
receiving ultrasonic sound energy. The black PVDF
plastic tip of the DT7 contains these crystals, which are
designed to be inserted to the average fluid velocity point
within a pipe. Not all liquid within a pipe is flowing at a
uniform fluid velocity. But, a straight run of pipe, full of
flowing liquid, contains a predictable liquid velocity profile.
By selecting proper upstream and downstream lengths of
straight pipe from the transducer installation point and
precise insertion depths into the pipe, very accurate and
reliable volumetric flow rates and totals can be realized.
Select a transducer mounting location with adequate
straight runs (without disturbances) of pipe, both upstream
and downstream, to achieve stable and accurate readings.
Examples of minimum upstream and downstream
requirements are included in Table 1. Note that if
adequate straight plumbing cannot be provided the D77
system will operate repeatably, but will probably not
achieve ideal accuracy.
When installing the DT7 transducer in a horizontal pipe,
the preferred orientation is at least 20 degrees from the
top or bottom of the pipe. Ensure that the mounting
location allows for adequate clearance to install and
retract the probe fully from the pipe.

The D77 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. 12/97 -12- D77X
PART 2 - TRANSDUCER INSTALLATION
Step B - Hot Tapped
Installation
The installation instructions cover Hot-Tapped
installations (installations where it is required to install or
remove the transd ucer probe without shutting down the
process pressure). If the product is being installed
without an isolation valve, ignore the steps that pertain to
its installation. Figure 3 illustrates an exploded view of
an isolation valve assembly and names the various
components.
If the DBV or DSSV accessory kits were ordered with the
DT7 probe, a Hot-tapped installation can be conducte d.
The kits include an isolation valve assembly and is
designed for installation in pipes under pressure, up to
700 psi at 70? F.
All items required for installation are provided with the kit,
except for the 1.5" NPT weld coupling or service saddle
and the drilling and welding equipment. These
instructions call for the use of a drilling machine
designed for operations under pressure (for example,
Muller Co., Decatur, Illinois).

Step C - Component
Assembly
Procedures are as follows:
1.Verify that the pipe’s line pressure is
rated limits of the pressure drilling mach
2. Grind off paint or other coatings from the pipe in the
area where the DT7 Probe Assembly is to be
installed. Recommended minimum straight pipe
lengths for best accuracy are 10 diameters upstream
and 5 downstream.
3. Tack weld a 1 ½"NPT weld coupling to the pipe or
install service saddle according to the suppliers
instructions. The coupling or saddle must be aligned
perpendicular to the pipe axis and square to its plane.
4.Complete welding. A water tight, 0.25"
weld bead is recommended.
5.Install the close nipple (supplied with
into the weld coupling. Use appropriate pi
6.Install the isolating ball valve on the
close nipple. Verify that the valve is in fully open position.
7.Install drill bit and adapter into the
pressure drilling machine. Then attach the machine to the
isolation valve.
8. Drill through the pipe wall in accordance with the
instructions supplied with the drilling machine.
9. Withdraw the drill bit through the isolating valve.
Close the valve and remove the drilling machine.
Check for leakage at valve and connections.
10. Place pipe sealant on the 1-½” NPT threads of the
Insertion Fitting assembly. Screw the assembly into
the isolation valve and tighten with a 2-½” Pump
wrench.

M = INSERTION DEPTH
M = P - IL - T - H - 0.67”
PROBE INSERTION
Before beginning the probe insertion procedure, it is
necessary to calculate the probe insertion depth of the
sensor. For normal pipe runs, the probe tip must be
located at 1/8th of the pipe inside diameter. Figure 4
outlines the Necessary measurements and calculations
that will be needed to insure that the probe tip is at the
proper insertion point.
Figure 4
Rev. 12/97 -15- D77X
PART 2 - TRANSDUCER INSTALLATION
In order to calculate the proper insertion depth of the
probe several pieces of data will have to be collected. The
following fi ve constants defines the variables found in the
insertion depth calculation.
P = The overall length of the probe. This measurement
is taken form the top of the probe flange to the very
tip of the sensor. Subtract 0.67" from this
measurement and record this figure.
H= The distance from the bottom of the insertion
\retraction rod assembly flange to the outside wall
of the pipe.
T= Is the wall thickness of the pipe. The Appendix
provides wall thickness of a wide range of pipe
sizes and schedules. If the pipe size and schedule
are not found in the appendix, your pipe supplier
should be able to provide you with this data.
Important!
I.L.= The insertion point in the pipe. This is calculated
by multiplying the pipe inside diameter by 0.125.
M = The distance from the top of the probe flange to the
bottom of the insertion\retraction rod assembly
flange
M= P- I.L. - T- H
To insure that the probe tip is inserted to the proper
insertion point, the distance M, which is described above
should be measured and set very carefully.
Rev. 12/97 -16- D77X
PART 2 - TRANSDUCER INSTALLATION
Step E - Cable Routing
PROBE CABLES
Before inserting the probe into the pipe, the sensor cables
should be routed to the transmitter location. Verify that
the supplied cable length is sufficient to meet the
installation requirements. If the supplied length is found to
be insufficient, contact the factory to make probe
exchange arrangements.
CAUTION: Do not proceed with probe insertion should
the supplied cable length be insufficient for the installation.
Probes that have been exposed to process liquids are not
exchangeable.
CAUTION: The probe cables are designed to carry low
level signals that are developed by the sensor. Care
should be taken in routing the cables. Avoid running
cables near sources of high voltage or EMI\RFI. Also
avoid routing the cables in cable tray configurations,
unless the trays are specifically used for other low
voltage, low level, signal cables.
CAUTION: The internal DT7 Probe wiring is epoxy
encapsulated to seal it from moisture. The Probe is
provided with two coaxial cables to shield the low level
signals and must be continuous to the DT7 Probe
Transmitter. Do not splice the probe cable to extend it's
length as the integrity of the shielding must be maintained
to insure proper sensor operation. The cable may be cut
to a shorter length. If you have extra cable do not coil the
excess wire in the enclosure.
1. Run the lower Jam nuts down to a point that
approximates the final insertion position or at least far
enough to allow insertion into the Insertion Fitting. Using
the threaded rods as a guide, position the probe in the
Insertion Fitting. Continue to insert the probe as far into
the isolation assembly as possible. The probe tip will
come in contact with the closed "ball" in the isolation
valve.
Rev. 12/97 -17- D77X
PART 2 - TRANSDUCER INSTALLATION
Figure 5
CAUTION: Do Not Force the Probe Tip Against the "Ball",
damage to the probe tip may result.
2. Replace the upper Jam Nuts ( 2 on each rod) and the
cotter pins. The nuts should be run down to the top side
of the retaining collar and the cotter pins replaced. Orient
the probe in the direction of flow as indicated on by the
FLOW direction arrow located on the top of the probe
flange. See Figure 5. Lock the probe in position with the
enclosed allen wrench.
CAUTION: The nuts on both ends of the retaining
rods must always be in place as a safety measure to
prevent possible probe blow out. Inserting cotter pins is a
further safety measure.
3. Slowly open the isolation valve. When the valve is fully
open, use the proper size wrench on the insertion nuts,
alternately tightening each nut about two complete turns
to avoid uneven seal loading.
NOTE: For some low pressure\low temperature (less
than 30 PSIG and less than 100o F (38oC) the probe may
be pushed in by hand to decrease the insertion time.
Rev. 12/97 -18- D77X
PART 2 - TRANSDUCER INSTALLATION
Retracting the Probe
PROBE RETRACTION PROCEDURE
1. Retract the Probe by loosening the Upper Jam nuts
counterclockwise as viewed from the top of the probe
using the proper size wrench. If the pipe is under
pressure, the nuts must be turned alternately about two
turns at a time to prevent, binding as a result of
non-equal seal loading. In many cases, the line pressure
will cause the probe to retract. Should the probe bind, use
the retraction nuts on the lower side of the probe flange to
assist in the probe retraction. Continue this procedure
until the Probe is fully retracted into the Isolation Valve.
CAUTION: Do not run the drive nuts off the rods until the
isolation valve is fully closed.
2. After the
Probe is retracted past the "ball” in the isolation valve, the
Isolation Valve may be closed to isolate the Probe from
the line and the probe can be removed entirely.
3. CAUTION: If the se nsor is not above the "ball" of the
isolation valve, the valve cannot be closed. If the valve
will not close smoothly, the body or tip of the probe is most
likely not above the "ball". Attempting to force the valve
into the closed position may result in damage to the
sensor.

Transmitter
Installation
The D77 enclosure should be located in an area that is
convenient for observation of the LCD readout and keypad
operations.
1. Place the D77 transmitter in a location that is:
? Where little vibration exist.
? Protected from falling corrosive fluids.
? Within ambient temperature limits - 22 to 122°F [30 to
50°C]
? Out of direct sunlight. Direct sunlight may increase
temperatures within the transmitter to above maximum
limit.
2. Mounting: Refer to Figure 6 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 flat
surface with four appropriate fasteners.
3. Conduit holes. Conduit hubs should be used where
cables enter the enclosure. Holes not used for cable
entry should be sealed with plugs.
NOTE: Use NEMA 4 [ IP65 ] rated fittings plugs to
maintain the water tight integrity of the enclosure.
Generally, the left conduit hole (viewed from front) is used
for line power; the right conduit hole for transducer
connections.
4. If additional holes are required, (analog outputs, etc.)
drill the appropriate size hole in the enclosure’s
bottom. Use extreme care not to run the drill bit into
the wiring or circuits cards.

NOTE: An additional hole in the transmitter enclosure is
required for outputs. Drill the hole in the the enclosure
bottom taking care not to drive the drill bit into wiring or the
circuit boards with the transmitter.
The CTR pulse output is proportional to the flow rate
measuring scale. This output may be used one of two
ways:
? To drive a 12V logic device.
? To drive a low impedance, 12V device. Minimum
resistance 50 ohms.
The pulse output pulses with totalizer increments. The

PART 3 - STARTUP AND CONFIGURATION
Before Starting the
Instrument
Instrument Startup
Important!
Note: The D77/DT7 flow meter system requires a full pipe
of liquid before a successful startup can be completed.
Do not attempt to make adjustments or change
configurations until a full pipe is verified.
Procedure:
1. Verify that all wiring is properly connected and routed.
2. Apply power. The POWER indicator will illuminate.
3. Press the SIGNAL STR key and verify SIGNAL STR
counts greater than 100. Adjust the GAIN (R13 on the
Main PCB) control so that a reading greater than 100
counts is observed. It is rare that this setting will need
adjustment from factory settings.
Note: It is undesirable to adjust the GAIN 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/zero SIGNAL
STRENGTH and FAULT indication at ZERO fl ow.
Rev. 12/97 -24- D77X
PART 3 - KEYPAD CONFIGURATION
After a successful flow meter installation and startup
(covered in the previous sections of this manual) the D77
can be keypad configured to provide select engineering
unit readings of flow and a scaled 4-20mA 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, FPS or MPS, are the
only required measurement keypad configuration is not
required.
UP/DOWN Arrows
Allow changing of the D77 configuration constants. Use
the UP arrow to increase constant values and the DOWN
arrow to decrease values. The arrows can be
momentarily pressed to change values incrementally or
held to advance continuously. Constants outside of the
valid range of the D77 cannot be displayed. The scrolling
rate at which the values will change is two tiered.
Scrolling will be relatively slow during the first five seconds
of a continuous keypad press; the scrolling rate will
increase after that time to allow rapid changes of large
values.

does not appear in the table, consult the pipe manufacture
or conduct a physical measurement of the pipe internal
diameter. Errors in the entry of this value can result in
large inaccuracies.
FULL SCALE
Allows entry of the maximum fluid velocity anticipated
within the pipe. This value does not have any bearing on
displayed flow rates or values, but is used to scale the
span value of the 4-20mA analog output. If the analog
output is not going to be utilized set this value to 30.00 if
measuring in U.S. units or 10.00 if measuring in metric
units.

second). Valid ranges for this entry are 0 to 10.00
MPS. Two equations that relate liquid velocity to
volume are
LPM = 0.047 X I.D.2 X MPS
MPS = ( LPM X 21.28) / I.D.2
I.D. in inches
Note: Attempting to set a FULL SCALE value of less than
0.5 FPS [0.15 MPS] may result in an unstable transmitted
output. If flows are typically lower than this range, the
LOW FLOW FILTERS and higher DAMPing values may
be required.
UNITS
Utilized to set engineering units of measure. There are
twelve different selections possible. The Table 2 lists the
entry code number, flow rate unit of measure and totalizer
unit of measure.
Note: After changing the UNITS value, it may be
necessary to change other configuration values
accordingly. For example, FULL SCALE, I.D., HIGH/LOW
ALARM are influenced by th e UNITS entry.
Note: Flow already accumulated will not be correctly
compensated for if the UNITS of measure changes.

HIGH ALARM (Labeled RELAY-1 on the Main PCB)
Controls the set-point of the SPDT relay labeled RELAY-1
on the Main PCB. Enter a liquid velocity at which a relay contact action is desired. Relay contacts are utilized for
signaling flow rate conditions that are higher of lower than
a desired set point. If a relay setting is made very close to
a nominal liquid velocity, relay “chatter” ( rapid opening
and closing of the relay ) may result.

TOTAL MULT
Utilized for setting the flow totalizer exponent and
changing the External Counter output. This feature is
Rev. 12/97 -29- D77X
PART 3 - KEYPAD CONFIGURATION
useful for accommodating a very large accumulated flow.
The exponent is a “ X 10n” multiplier, were “n” can be from
0 (100, X 1 multiplier) to 4 (104, X 10,000 multiplier).
The External Counter output, available at the two
terminals labeled CTR on the Main PCB, is influenced by
the TOTAL MULT value. Since the output is designed to
operate electromechanical accumulators, large flow rates
will require that the TOTAL MULT be set to a value usable
by these types of counters (typically speeds no faster than
3 cps). The following chart tabulates suggested settings

Third press Restarts the internal
totalizer/external CTR
(The internal totalizer starts
from zero.)
If inhibiting (pausing) the totalizer is necessary, there are
two methods suggested:
1. Connect and external totalizer to the CTR terminals.
See the section of this manual related to CTR
electrical connections for connection parameters.
2. To inhibit the internal totalizer without resetting the
accumulation, press the TEST key to pause the
accumulation. Press the ENTER key to resume
accumulation.
LOCK ON
To ensure security of the configuration and accumulated
flow, the keypad can be locked. To enable the keyboard
lock out, press LOCK ON key, the display will show
LOCK ON. Press ENTER to return to Run mode. To
turn the lock off, press the LOCK ON key. Use the arrow
keys to set a value of 125. Press the ENTER key. The
display will show LOCK OFF to acknowledge that all
keypad entries can now be made.
CAL
A few factors can influence the readings of a D77 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:
? Operations on liquids with sonic velocity carrying
properties that are different from water.
Rev. 12/97 -31- D77X
PART 3 - KEYPAD CONFIGURATION
? Transducer mounted in non-recommended locations.
By applying a CAL value other than 100%, the factory-
calibrated readings will be altered by the percentage
entered. This CAL value will be reflected in the display, 420mA and CTR outputs and relay settings.
For example, if a reading of 175 GPM is displayed and the
known flow rate is 160 GPM, a CAL value of
160 GPM x 100 = 91.4%
175 GPM
The D77 will not allow decimal values to be entered as a
CAL constant, so round to the nearest whole number; in
this case 91%.
Acceptable input ranges for the CAL constant are 0-255%.
DAMP
In installations where very turbulent or erratic flow is
encountered, increasing the Damping setting can increase
display and output stability. The DAMP setting increases
and decreases the response time of the flow meter display
and outputs. To set the damping time constant, press the
DAMP key. Set a value between 1 and 10, 1 having the
fastest response and 10 having the slowest response.
Press ENTER to complete the configuration.
TEST
The meter contains a test function for verification of the 420mA analog and CTR external counter outputs. To
activate the test function, press the TEST key. Verify that
20mA is flowing in the 4-20mA output and verify that the
CTR output is supplying 100mS pulses. Press ENTER to
exit the test function.
2nd FUNCT - SERVICE MODE
Rev. 12/97 -32- D77X
PART 3 - KEYPAD CONFIGURATION
{2nd FUNCT} SIGNAL STR
Displays the raw Doppler signal strength value. This
value will increase as the velocity of the liquid increases.
Typically, a liquid flowing at a velocity greater than 0.2
FPS [0.06 MPS], with adequate suspended solids (25 ppm
or 30 micron or larger solids) or aeration, will produce
SIGNAL STR readings over 150 counts.
NOTE: If the liquid is not flowing a low SIGNAL STR
reading is non-conclusive. If a high SIGNAL STR is
indicated at zero flow rate, it indicates that a source of
interference (another ultrasonic instrument, VFD, or poor
electrical ground) may be present. Verify that SIGNAL
STR increases when the flow starts. If it does, increase
the SS CUTOFF setting (see SS CUTOFF).
If SIGNAL STR is lower than 100 counts in a f lowing
liquid, one or more of the following steps may need to be
invoked:
1. If the liquid velocity is less than 1 FPS (0.3 MPS) turn
SW-1 “LOW FLOW” switch ON. (This dual DIP switch
is located near the center of the Main PCB.)
2. If SW-1 did not cause an increase in SIGNAL STR to a
level above 100, turn ON SW-2.
3. There may not be adequate reflectors for the Doppler
principle to operate. The DT7 probe can be relocated
to a source of liquid degasification, such as would be
found a 1-3 diamet ers down stream of a 90-degree
elbow. A surrogate source of aeration can also be
introduced by bleeding a small amount of compressed
air into the line several diameters upstream of the DT7
probe.
{2nd FUNCT} 4 mA
The 4-20mA output on standard D77 flow meters is scaled
Rev. 12/97 -33- D77X
PART 3 - KEYPAD CONFIGURATION
at zero flow equals 4mA and 20 FPS (6.08 MPS) equals
20mA. The 4mA key allows fine adjustments to be made
to the “zero” of the 4-20mA output or allows offset to be
placed on the 4-20mA output. To adjust the 4mA output,
an ammeter or reliable reference connection to the 420mA output must be present.
Procedure:
1. Either break the present current loop and connect the
ammeter in series (disconnect either wire at the
terminal block labeled 4-20mA on the Main PCB of the
D77) or, if this output is not being utilized, connect the
ammeter + to the + terminal and – to the – terminal of
the 4-20mA output.
2. Press the 4mA key.
3. With no flow moving through the pipe, adjust the
setting count using the arrow keys until 4.00mA is
indicated on the ammeter. Th e typical count value
range for this setting is between 3350 and 3850.
4. Press ENTER to store the value.
5. Re connect the 4-20mA out put circuitry as required.
{2nd FUNCT} VEL ADC
Press VEL ADC to display the raw analog to digital
converter counts that are being processed by the
microprocessor. This count value will vary linearly with
flow rate from 0000 at zero flow rate to 1024 at m aximum
full-scale flow rate. No modifications of this count can be
made, this display is for diagnostic purposes only.
{2nd FU NCT} BLANKING
This key is unused.
{2nd FUNCT} 20mA
The 4-20mA output on standard D77 flow meters is scaled
Rev. 12/97 -34- D77X
PART 3 - KEYPAD CONFIGURATION
at zero flow equals 4mA and 20 FPS (6.08 MPS) equals
20mA. The 20mA key allows fine adjustments to be made
to the “span” of the 4-20mA output. To adjust the 20mA
output, an ammeter or reliable reference connection to the
4-20mA output must be present.
Procedure:
1. Either break the present current loop and connect the
ammeter in series (disconnect either wire at the
terminal block labeled 4-20mA on the Main PCB of the
D77) or, if this output is not being utilized, connect the
ammeter + to the + terminal and – to the – terminal of
the 4-20mA output.
2. Press the 20mA key.
3. With maximum flow moving through the pipe, adjust
the setting count using the arrow keys until 20.00mA is
indicated on the ammeter. The typical count value
range for this setting is between 1450 and 1950.
4. Press ENTER to store the value.
5. Re connect the 4-20mA output circuitry as required.
{2nd FUNCT} SS CUTOFF
This entry represents the signal strength cutoff level (low
velocity cutoff). At flow rates below 0.2 FPS [0.06 MPS]
the readings displayed by the D77 are unreliable. By
utilizing the default SS CUTOFF of 100 counts, small
unstable readings at low flow rates will be avoided.
Note: If SS CUTOFF is set to a level higher than the
SIGNAL STR value the meter will not show flow or output
any values.
{2nd FUNCT} INPUT F.S.
This key is used to select a maximum velocity that the
Rev. 12/97 -35- D77X
PART 3 - KEYPAD CONFIGURATION
instrument will operate. Choices are 10, 20 and 30 FPS.
It is not recommended to deviate alter this value from
factory settings, as certain spans have been set that
correlate to the set maximum velocity. Consult the
Dynasonics factory for adjustment procedures.
{2nd FUNCT} DAC 3
This key is not used.
{2nd FUNCT} BACK LIGHT
Toggles the electro-luminescent LCD back lighting ON
and OFF. This type of back lighting has an illumination
half-life of approximately one year. If the instrument is left
unattended for long periods of time, turning the back
lighting OFF can preserve the electro-luminescent panel
and save a small amount of power.
{2nd FUNCT} CONTRAST
This setting allows the adjustment of the LCD contrast.
An LCD’s viewing quality is affected by temperature,
ambient lighting, back lighting and viewing angle. Adjust
the contrast level to provide the best contrast possible.
Default count is 50.

MPS], adjust GAIN control (R13 on the
Main PCB) till SIGNAL STR reaches at
least 130 counts.
? On cleaner liquids, move the
transducers closer to a 90o pipe elbow.
? If GND connection and pipe are at
different potentials, ground D77 to pipe
potential.
? If Variable Frequency Drives are being
utilized, verify that the D77 obtains a
flow indication when the pump turns
OFF. If it does, contact the Dynasonics
factory.
Rev. 12/97 -37- D77X
PART 4 - TROUBLE SHOOTING
Stability of flow readings are
unsatisfactory
Erroneous Reading
? Increase the DAMP constant from keypad.
? Move transducers to a location further
from piping tees, elbows, valves, filters,
etc.
? Transducer mounted incorrectly or not
true to the pipe.
? Another local ultrasonic instrument is
operating at about the same frequency
[ consult the Dynasonics factory].
? 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 D77. Power the meter with
a circuit that does not power motors,
ballasts or switching supplies.
The D77 display indicates flow, when
true fluid velocity is zero.
Rev. 12/97 -38- D77X
? Verify that residual leakage and flow is not
present. [I.e. leaking check valves]
? Verify that GAIN control (R13 on the Main
PCB) is not adjusted too high. With
nominal flow running through the pipe,
adjust GAIN control till the display zeros
with no flow.
