24 Model C-ET Installation Guide
1.3.3.5 Mounting the Transducers (cont.)
Before the C-ET transducer can be permanently inserted into the clamp, solid sheet couplant must be applied. To do
this, lay the solid sheet couplant over the transducer face and bend the ends over the transducer’s heel and toe.
Temporarily secure the couplant to the heel and toe with electrician’s tape. Do not apply the tape to the pipe contact
surface. Tape will burn/fall off after time.

8. Install the sensors into the yokes taking care not to shift the couplant. Tighten the hold down bolts to 15 ft-lbs,
20 N-m. Tighten the backing nut.
9. Reinstall the insulation up to the line engraved on the sensors.
CAUTION!
Not reinstalling the insulation up to the engraved line could cause permanent damage to the C-RS
transducer.
You have completed installing the V clamping fixture and transducers. You should do all of the following:
• Refer to the installation section of your User’s Manual or Startup Guide to make transducer connections.
• Make a note of the installation date and set a schedule for periodic inspection and tightening of clamping
fixture nuts to ensure the clamping fixture does not become loose and fall, possibly causing injury.
• Once the flowmeter is up and running, measure the signal strength upstream and downstream using the
flowmeter’s diagnostics menu and make a note of it. This value will be helpful when making periodic checks.
Refer to your User’s Manual or Startup Guide for more details.
