Warning:
Do not over-tighten the cable ties or kink the
sensor cables! The sensor cable sheathes two
components: the electrical cables that operate the sensor
and an air tube that ventilates the pressure sensor (
when
applicable ). Over-tightening the ties or kinking the cable
can damage or restrict the air tube, causing erroneous
pressure depth readings. In addition, make sure the
connector-end of the sensor is not kinked, does not contain
moisture, and includes an attached dryer tube filled with
active
blue desiccant.
4. Use the diagonal cutters to cut off the excess portion of the
cable ties.
Mounting the ParaDepth, ParaFlow, Surface
Combo Sensor or Ultrasonic Depth Sensor
The ParaDepth, ParaFlow Surface Combo/Ultrasonic Depth sensors
are not mounted prior to installation of the ring. The ring
mechanism and sensor mounting plate are assembled as detailed in
Assembling the Ring beginning on page 5-12. After the ring is
installed at the monitoring site, the sensor is inserted into the
mounting plate and leveled (as
described in the following section ).
Installing the Ring in the Pipe
The ring must fit securely in the pipe with the sensors properly
positioned to ensure the most accurate monitoring results. Install
the ring in the pipe in the following way:
1. Examine the pipe for possible obstructions to the flow or
inhibitors to ring installation.
2. Adjust the ring size to slightly less than the pipe diameter
before placing the ring in the pipe by turning the spreader
mechanism adjustment nut
clockwise to contract it.
