2.9.4 Installing the transducers
1. Check to be sure the second CFG-PI holder bracket is
correctly positioned.
2. Apply a bead of CPL-16 couplant 6 mm (0.25 in.) wide on
each transducer face (see Figure 38 below).

Note: Do not slide the transducer with couplant along the
surface of the pipe when mounting the transducer.
3. With one hand, mount one transducer into the PI fixture.
With the other hand, tighten the thumbscrew, gradually
pushing the transducer down to the pipe surface. Use a
wrench to tighten the backing nut to prevent loosening
due to vibration and thermal expansion.
IMPORTANT:
Do not use pliers or a wrench on the thumbscrew.
4. Repeat step 3 for the other transducer.
2.10 Making electrical connections
The PanaFlow LC utilizes the XMT1000 Transmitter module.
For information regarding electrical connections required
for setup of the XMT1000 Transmitter, please refer to the
included PanaFlow LC User’s Manual.
WARNING!
Make sure all covers, with their O-ring seals,
are installed and the set screws tightened
before applying power in a hazardous
environment.
Attention European customers!
To meet CE Mark requirements, all cables
must be installed as described in Appendix D,
CE Mark Compliance.
2.11 Transducer wiring
The PanaFlow™ LC is a 1, 2 or 3 channel clamp-on ultrasonic
flowmeter. For three channel applications there will be an
additional Aluminum or Stainless-Steel junction box for
transducer connections. The transducer wiring installation
for either of these junction boxes will be the same. The Figure
39 below shows both boxes:
WARNING!
Make sure that there is no power in the
XMT1000 meter and it is not plugged. Failure
to do so may result in electrical shock that
can cause injury, or death.
