Note
Do not smear couplant while mating sensor to pipe.
9. Position clamp plate screw assembly into notch and slide over sensor.

Note
Each enclosure will have one sensor from each opposing sensor set; i.e. The enclosure
housing at path 1 will have the "A" sensor from set 1 mounted in the upstream location
and the "B" sensor from set 2 will be mounted in the downstream location. The enclosure
housing for path 2 will have the "A" sensor from set 2 mounted in the upstream location
and the "B" sensor from set 1 will be mounted in the downstream location.
