Product Overview
Introduction Thermo Fisher’s Polysonics SX30 portable Doppler flowmeter generates
two independent ultrasonic signals at different frequencies. By correlating
these frequencies, the instrument automatically identifies and eliminates
noise errors from sources such as variable frequency drives.
In addition, operation of the instrument is enhanced by an Expert System
that allows the flowmeter to automatically “learn” the application
parameters. As a result, the flowmeter can be easily commissioned in a
fraction of the time required to configure competitive ultrasonic
flowmeters.

Installation & Wiring
Installing the
Transducers
1. Select an installation site:
Keep the following questions in mind when choosing a proper
installation site:
●Is the chosen section of pipe always full of liquid?
●Are there at least 5 pipe diameters upstream and 3 pipe diameters
downstream from any directional changes, pipe joints, or
narrowing/widening of the pipe?
Figure 2–1.
Conditions at locations A, B, C, D, and E can interfere with the
transmission of the ultrasonic wave and yield inaccurate or unreliable
flow readings:
●A: Pipe may not be full
●B: Down flow
●C: Too close to elbow
●D: Air collects at the top of the horizontal pipe
●E: Sediment collects at the bottom of the horizontal pipe
Note Selecting the proper installation location is essential to flow
measurement reliability. Each application is unique and may require a
variation of installation locations. ▲

Installation & Wiring
Installing the Transducers
2. Select a transducer orientation:
Refer to Figure 2–2. If your application allows, install the transducers at
the 3 and 9 o’clock locations. Ensure the transducers are parallel to
each other along the pipe circumference.
Figure 2–2.
3. Attach the transducers to the pipe strap:
a. Use a screwdriver to loosen the mounting screw and slide the lock
back on each transducer.
Figure 2–3.

Installation & Wiring
Installing the Transducers
b. Place the pipe strap across the mounting, and slide the lock back
into place.
Figure 2–4.
c. Tighten the screws.
Figure 2–5.
4. Mount the transducers, ensuring the transducers face the same
direction (as shown in Figure 2–6):
a. Wrap the pipe strap around the pipe, and slide the end of the pipe
strap through the tension nut assembly.
b. Pull the strap tightly, and clamp the tension nut down to secure the
strap to the pipe.
c. Loosen the mounting screw of a transducer, and move the
transducer to the 3 o’clock position on the pipe. Tighten the
mounting screw to secure the transducer.
d. Loosen the mounting screw of the second transducer, and move the
transducer to the 9 o’clock position. Tighten the mounting screw
to secure the transducer.
e. Remove the strap from the pipe, and apply sonic coupling
compound to each transducer surface.
f. Reposition the strap on the pipe, placing the transducers in the
proper positions.

g. Tighten the tension nut assembly with a 3/8-inch hex nut driver to
secure the strap.
Note Increasing the pipe strap tension improves signal transmission. ▲

Operation & Configuration
Configuration
Configuration Note the following before configuring the meter:
●You must know the pipe internal diameter (ID) to ensure reliable flow
measurements. If you do not know the pipe ID, go to Appendix A.
●There must be flow in the pipe when you start the meter.
There are two modes of operation. Consider using auto mode if your
application is a constant process. The instrument default is the auto mode.
Apply power to the meter, and begin the configuration process by selecting
Auto or Manual operating mode. Once you have completed the
configuration process, you can access these screens from the Flow screen by
selecting Setup > Config.
Auto Mode 1. Pipe ID screen:
a. Enter the pipe ID, and press Enter.
b. Use the scroll key to select the measurement units (inches, mm).
Press Enter to select the unit.
c. Select Next to move to the next screen.
2. Flow Units screen:
a. Use the scroll key to select the flow units (US gallons, million
gallons, cubic meters, oil barrels, Imperial gallons, cubic feet, liters,
liquid barrels), and press Enter.
b. Use the scroll key to select the time base for flow measurement
(seconds, minutes, hours, days), and press Enter.
c. Select Next to enter learn mode.
3. The meter displays status of the learning process. Refer to “Learn Mode
Warnings” (Table 6–2 in Chapter 6) if you receive one of the following
messages:
●Invalid Signal, Can’t Learn
●No Flow, Can’t Learn
●Warning Low S Strength
●Warning Poor S Strength
