appropriate section in the manual for complete details.

1. TRANSDUCER LOCATION

A. In general, select a mounting location on the piping system

with a minimum of 10 pipe diameters (10 × the pipe inside

diameter) of straight pipe upstream and 5 straight diameters

downstream. See Table 2.1 on page 2.3 for additional

configurations.

B. Select a mounting method for the transducers based on pipe

size and liquid characteristics. See Table 2.2 on page 2.5.
