Mounting sensors
Install the mounting assemblies and sensors directly on top of the damping material. Use
liquid couplant (7ME396000UC20) for all clamp-on gas installations or if signal amplitude is
low or marginal.
Follow the instructions in the manual for installing the sensors into the mounting assemblies
and securing (see Installing sensors in Reflect mode (Page 30)).
1. Connect sensor cables.
2. Return to the transmitter and complete installation process.
Cautions on the use of dry film couplant
● Don't clean the sensors or pipe surface with MEK, acetone, trichloroethane,
trichloroethylene, toluene, freon (and its vapors), chloroform, and xylene.
● Don't use on oily or greasy pipe surfaces. It will interfere with adhesion.
