The pipe clamp on the supports should have a large surface area contact with the support and
process pipe. No rubber, plastic or other material should be installed between the clamp and
process pipe. The transducer should be supported and clamped free of tension on either side
of the flanges as illustrated. The clamps should be equidistant and as close to the flanges as
possible.
Do not mount supports on flanges or on the housing.
Process pipes on either side of the transducer should be axially aligned, and flanges should be
parallel face to face within 0.4 mm (.016 in). the installation dimension (L) across the
transducer flanges must be matched to the process pipe flanges within
±
2 mm (.079 in).
For long pipe runs additional pipe supports must be installed 1 to 2 transducer lengths (L)
apart (fig. 14).
