A. TRANSDUCER LOCATION

Selecting the proper location for taking a flow measurement is the single

most critical step in the operational procedure. The transducer utilized

by the UFX flow meter contains two piezoelectric crystals for transmitting

and receiving ultrasonic signals through the wall of a pipe. Select a

transducer location with adequate straight runs (without flow disturbances)

of pipe, both upstream and downstream, to achieve stable and accurate

readings. Examples of common piping configurations and the recom-

mended minimum upstream and downstream pipe lengths are included

in Table 1.

FLOW

Note: If adequate straight plumbing cannot be provided the UFX will

operate repeatably, but will most likely not achieve ideal accuracy.
