Sensor cabling
2. Continue securing the cables until reaching the top of the pipe.
3. Pull the ties until they are taut.
Warning: Do not over-tighten the cable ties or kink the
sensor cable! The pressure depth sensor cable sheathes
two components: the electrical cables that operate the
sensor and an air tube that ventilates the sensor. Over-
tightening the ties or kinking the cable can damage or
restrict the air tube, causing incorrect 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.
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.
