Product Overview
Introduction
Ordering
Information
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.
Refer to the following list of part numbers to order spare parts for your
instrument.

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:
Thermo Fisher Scientific Polysonics SX30 User Guide 2-1
● 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. ▲
