2. Apply a thin bead of couplant to one of the transducers.
A bead approximately the size of a toothpaste bead
should be placed down the center of the transducer
face.

Panametrics supplies an ultrasonic couplant for your
clamp-on installation. The purpose of the couplant is
to provide reliable transmission of ultrasound between
two adjacent solid surfaces. Couplants perform this task
by excluding air from the space between the adjacent
surfaces. Accordingly, the clamp-on transducers should be
pressed tightly against the pipe, using hand pressure on
the set screw to squeeze the couplant to as thin a film as
practical for the given pipe surface.
Panametrics provides couplants for both permanent and
temporary use as well as for high-temperature and low-
temperature applications. For long-term installations, make
sure the couplant does not dry out or extrude. Standard
couplants supplied from Panametrics for the PanaFlow™ LC
are listed in Table 1 below.

CPL-1 Standard -40 to +240°C Semi-Permanent
CPL-8 Solid Sheet -40 to +260°C Permanent
3. Determine the upstream and downstream ends of the
pipe and place the appropriate transducer into the
corresponding block on one of the sub-assemblies.
Make sure the transducer cable connector faces away
from the center of the installation.
