3.5 Sensor Installation
3. Wrap a Mounting Strap around the pipe. Make sure to position it so there is easy access
to the mounting strap adjusting screw.
4. At the mounting location, place the Mounting Frame/Spacer Bar Assembly on the pipe so
that it rests on the top of the pipe.
5. Engage the end of the Mounting Strap with the Mounting Strap Adjusting Screw.
6. Slide Mounting Strap under the spring clip of one of the Mounting Frames.
7. Tighten the Mounting Strap Screw enough to take up all of the slack, but not enough to
prevent rotation of the assembly.
8. Rotate the assembly on the pipe to the final conditioned location, ensuring that it is
straight along the pipe axis. (Refer to the sensor orientation diagram below.)
9. Tighten the Mounting Straps to seat the assembly firmly on the pipe. Do not over tighten.
10.Take either sensor and apply a continuous lengthwise 3mm (1/8-inch) bead of coupling
compound across the center of the sensor emitting surface.

11.Slide sensor into a Mounting Frames 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.
