Pressure Depth Sensor and Float Switch Installation 3-29
Note: If the pipe is large and the pressure depth sensor
cable cannot reach the pipe crown, attach the sensor cable
to ½-inch PVC tubing and anchor the tubing to the wall.
This will help prevent sensor damage during heavy flow.
Securing the Cable to the Band
Securing the pressure depth sensor cable to the band helps prevent
debris from collecting between the cable and the band or catching
on the loose cable. It also prevents the loose cable from disrupting
the flow.
Secure sensor cable as follows:
1. Starting at the appropriate sensor location, begin securing the
sensor cable with 4-inch x 0.08-inch cable ties through the pre-
drilled holes along the downstream trailing edge of the band up
the side of the band. Run the cable up the left side of the band
(when facing the downstream edge of the band).
Sensor cabling
2. Continue securing the cable 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
