TransPort™ PT878GC User’s Manual

3.1.2

Preparing the Pipe

Locate a transducer measurement point with 20 diameters of upstream straight run pipe and 10 diameters of

downstream straight run pipe. In addition, the point should be at least 10 diameters from any butt welds or

flanges. Keep appropriate clearance on either side of the pipe for easy transducer installation:

• 150 mm (6 in.) if you are not using a junction box, or
• 225 mm (9 in.) if you are using a junction box.

In general, transducers are installed 180° apart on opposite sides of the pipe and in a horizontal plane (at 3 and 9

o’clock). Figure 12 below illustrates the desired acoustic signal projection path for general installation; however,

additional pipe surveys may provide data that can lead to modifications for optimal installation.
