Securing the Cables to the Ring

Securing the Doppler velocity sensor and pressure depth sensor

cables to the ring helps prevent debris from collecting between the

cable and the ring or catching on the loose cable. It also prevents

the loose cables from disrupting the flow.
Secure the Doppler velocity and pressure depth sensor cables in the

following way:
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 ring up

the side of the ring. Run the cable up the side of the ring

opposite the spreader mechanism (the left side of the ring when

facing the downstream edge of the ring).

Note:

When securing both a pressure depth sensor and a

Doppler velocity sensor cable to the ring, place the

velocity cable on top of the pressure cable and secure both

together.

2. Continue securing the cables until reaching the ultrasonic depth

sensor or 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 cables!

The pressure depth 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, resulting in incorrect pressure depth readings. In
