BHGE 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.
BHGE 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 BHGE for the
PanaFlow™ LC are listed in Table 1 below.
