An acoustic coupling material must be placed between the transducer and the pipe
surface at the point where the sound waves enter the pipe.. Without this material, the
ultrasonic sound waves will not penetrate into the pipe. The Sonic-Pro meter package
includes two different materials for this purpose.
The blue gasket (part number 76001-417) should be used for permanent installations.
This gasket will be damaged be repeated installations.
1) Peel off the thin paper backing from the blue gasket and place the gasket on the
transducer completely covering the waveguide.
2) Remove the thick plastic backing from the gasket before positioning the transducer on
the pipe.
Dow Corning Silicone Seal #111 (part number 90008-394) may be used in place of the
gaskets if desired.
