the sensors (see diagram below).

5. Make sure that you have a matched pair of sensors. They both should have the same
S/N number but marked with either an "A" or "B" (e.g., 100A and 100B).
Dry film couplant/damping material
Each damping material kit contains one or more 229 mm x 914 mm (9" x 36" ) sheet(s) of
film to be cut and applied to the surface of the pipe whose flow is to be measured.
Depending on the sensor size code multiple layers may be required for optimal damping.
Refer to the table below for the correct kit P/N and final coating thickness specified for each
sensor size.
Note
Each kit contains the correct number of damping sheets (packaged in a mailing tube) for the
associated sensor size code.

Pipe
Smoothed Areas. If necessary, smooth an area large enough to accommodate sensors and
also several centimeters (inches) around the locations where the sensors are to be mount-
ed. Clean pipe again to remove any sanding residue.
