FIGURE 2.1A – RECOMMENDED INSTALLATION LOCATIONS
Do not install the transducers at the following locations:
A – Pipes may not be full
B – Down flow
C – Too close to the elbow
D – Air collects at the top of horizontal pipe
E – Sediment collects at the bottom of horizontal pipe
Conditions existing at these locations can interfere with the
transmission of the ultrasonic wave and yield
inaccurate or unreliable flow readings.

ocedures
Procedures
2.1 Install the meter
meter..
2.1.1 Select an installation location.
Selecting the proper location to install the transducers is essential to flow
measurement reliability. Each application is unique and may require
variations in the installation location.
NOTE
1.
2.
Review Figure 2.1a (Recommended Installation Location), on the facing page.
Select an installation location using Figure 2.1a and the following guidelines:
•
•
•
full pipe
flow in the pipe
5 pipe diameters upstream and 3 pipe diameters downstream from:
- a direction change on the pipe
- pipe joints
- a narrowing or widening of the pipe

2.1.2 Choose a transducer orientation.
Choosing the proper transducer orientation is essential to flow
measurement reliability. Each application is unique. You may need to
vary the orientation with each application, to achieve optimum meter
performance.
NOTE
1.
2.
Review Figures 2.1b,c (Transducer Orientations on Horizontal and Vertical
Pipe), on the facing page.
Meet the following guidelines to ensure optimum meter performance:
•
•
•
•
•
3.
3 o’clock and 9’oclock orientation
transducers parallel to one another along the pipe circumference
generous amounts of coupling compound
secure cable connections
tight pipe strap
IF your application does not enable you to mount the transducers at the
recommended “Best” orientation, THEN choose a “Good” or “OK” transducer
orientation OR choose a different location to install the transducers.

Pull the strap tight AND clamp the tension nut down to secure the pipe strap to
the pipe.
Loosen the mounting screw of one transducer.
Move the transducer at the 3 o’clock position on the pipe. (See Figures 2.1b,c
Transducer Orientations on Horizontal and Vertical Pipe, page 4)
Tighten the mounting screw to secure the transducer in place.
Repeat steps 4-6 for the second transducer, now at the 9 o’clock position.
Remove the pipe strap from the pipe AND generously apply sonic coupling
compound to each transducer surface.
Put the pipe strap on the pipe, placing the transducers in the proper position.
Tighten the tension nut assembly with a 3/8” hex nut driver securing the pipe
strap.
Increasing the pipe strap tension improves signal transmission.

Connect the communication cable from the flowmeter to the RS232 port on
the computer.
Start the HydraLink program.
Wait for the “Communications Established” window to appear.
Click on the “OK” button.
IF the “Communication Established window appears, THEN go the step 11.
IF the “Communications Failed” window appears, THEN check the security of
the cable, AND make sure the flowmeter is on.
Click on OK.
WHEN the CommPort Properties window appears, THEN make sure the
correct comm port number appears in the Port option, AND enter the correct
CommPort properties, show in Figure 3.6c - CommPort Properties, on the
facing page.
Wait for the “Communication Established” window to appear.
IF the Communication Established Window still does not appear, THEN
contact your Polysonics representative.
WHEN the HydraLink window appears, THEN click on the Log File 0 button.
(See Figure 3.6d - Select Log File, facing page)
Select the log file you want to download.
Click on the Get Log button in the upper right corner of the HydraLink window.
Wait for HydraLink to complete downloading.
The logger saves data in sequenced files 0 through 9. Once all the files
are full the logger restarts the sequence and overwrites the files
beginning with log file 0. Perform procedure 3.6.6 (Save the log files), on
page 23, to ensure data is not lost.

5.4.2 Factory Service
If Polysonics determines that the problem cannot be resolved over the phone,
return the entire unit to Polysonics.
Contact the Polysonics Service Center before returning an instrument for repair.
Mark the RMA number issued by the service representative on the outside of
the shipping box. The receiving dock will not accept shipments without an RMA
number.
You must include a letter fully explaining the symptoms of the failure as well as
details describing the application where the unit was being operated (type of fluid,
pipe size, pipe material, fluid velocity, temperature, etc.). Service cannot be
adequately performed until the Service Center receives this written information.
To ship an instrument to Polysonics:
1.
2.
3.
4.
Ensure that the instrument is well packed (in its original shipping box, if
available).
Include the letter of explanation.
Write the RMA number of the outside of the shipping box.
Send the unit freight-paid to the Service Center:

7.2 Pipe ID
7.2.1 Obtain the Pipe ID.
If you do not know the pipe ID, then try to get the Outside Diameter (OD) by one of
the following methods:
1.
2.
3.
4.
5.
Read the pipe Outside Diameter (OD) and schedule on the pipe
Read the OD and schedule from system drawings
Measure the pipe circumference using a tape measure, and divide the
measured circumference by 3.14 (Circumference ÷ 3.14)
For an approximate pipe ID use the OD with the charts in section 7.2.2 (Pipe
ID Charts), on pages 39-41.
For a more accurate pipe ID use an ultrasonic pipe thickness gauge (part
#0704/0187, available from Polysonics), AND perform the following
calculation:
pipe ID = pipe OD – (2 x pipe thickness)

7.3 Application Signal Quality and Signal Strength
Signal quality and signal strength are indicators of how well suited an application is
to a Doppler flowmeter. To determine the quality of your application:
1.
2.
3.
Look at the bottom right corner of the Flow screen.
Note the SQ number and the %SS number.
Refer to Figure 7.3b - Signal Quality/Signal Strength Chart, below, to
determine the quality of your application.

– the meter is not reading flow
– minimum quality, flow readings may be inconsistent or inaccurate
– flow readings are fairly accurate and consistent
– flow readings are accurate and consistent
To improve signal quality and signal strength see Table 5.3c (Action Codes), on
page 30.
