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, causing incorrect pressure depth readings. In
