Installing the Sensor
1. Take either sensor and apply a continuous lengthwise 3mm (1/8-inch) bead of coupling
compound across the center of the sensor emitting surface.

2. Slide sensor into a mounting frame back end first aligning the angled edge of the sensor
with the angled edge of the mounting frame. Keep sensor from making contact with the
pipe until it butts up against the mounting frame stop. Push sensor down to mate with
pipe.
3. Tighten the sensor clamping screws to hold the sensor firmly in place.
Repeat procedure
for the other sensor.
4. If installing a temperature sensor proceed to Mounting Temperature Sensor (Page 71). If
not, proceed to Sensor Wiring (Page 43).
5.6.4 Direct Mount
Sensor Installation using Mounting Frames, Spacer Bar and Spacing Guides
The combination of mounting frames, spacer bar and spacing guides is the recommended
way to mount Direct Mode sensors. The mounting frame establishes the axial alignment of
the sensors and allows you to remove and replace either sensor while preserving their exact
mounting location.
For Direct Mode mounting, a spacer bar is used to establish the distance between sensors
and a spacing guide to locate the sensors at the nine o’clock and three o’clock positions.
Should the distance between sensors be beyond the span of a spacer bar, a measuring tape
can be used. The Mylar spacing guide comes in various lengths and widths to accommodate
most pipe sizes.
