4. Expand the ring by turning the spreader mechanism nut
counter-clockwise with the crank handle or socket. However,
do not tighten the ring against the pipe completely at this point.
5. Mount the ParaDepth/ParaFlow/Surface Combo/Ultrasonic
Depth sensor to the ring by inserting the studs on the back of
the sensor into the keyholes on the sensor mounting plate (at
the top of the ring) and sliding the sensor back (in a
downstream direction) until it is fully in place. The sensor
cable should exit the downstream edge of the ring. Orient the
sensor with the depth crystals facing downward toward the
inside of the ring (flow surface).
