Installation Procedure
1. After receiving the Number Index from the Installation Menu, prepare the pipe surface
area where the sensors will be mounted. Check to ensure that you have a matched set of
sensors. They both should have the same S/N number but marked with either an "A" or
"B" (e.g., 100A and 100B).
2. Degrease the surface and remove any grit, corrosion, rust, loose paint, etc.
3. Assemble the sensors to the spacer bar, with the cable connectors facing away from
each other as shown above. The spacer bar is attached to a sensor using a sensor index
screw.
4. One sensor is attached using the "REF" hole on the spacer bar. The second sensor is
attached to the spacer bar at the index hole specified by the Number Index recorded in
Step 1.
Note
In some cases, the sensors may have two sets of securing holes. When using the EZ
Clamp assembly, use the lower set of holes when attaching the spacer bar.
5. Temporarily position the assembly (in the 10 o’clock position) at the location where it will
be mounted. Ensure that this is a smooth area of the pipe without any raised spots
(seams, etc.).
6. With a pencil or chalk mark a generous area around each sensor where they contact the
pipe. Remove the assembly.
7. Prepare the two areas you marked by degreasing the pipe surface. Remove any grit,
corrosion, rust, loose paint or surface irregularities with the abrasive pipe conditioning
material provided.
8. Remove the sensor from the spacer bar that was attached through the REF hole. Attach
the EZ clamp to the sensor under the spring clip. The adjusting nut knob should be
pointing up and on the side opposite the spacer bar. Unscrew the knob until it’s at the
stop.
