Pressure Depth Sensor Bottom of the ring slightly to the
left of the Doppler velocity sensor (when present)
Proper positioning of sensors on the ring
Caution: Handle all sensors and cables with extreme
care. The sensors and cables contain delicate mechanisms
and electronics. Keep sharp objects away from sensor
cables, and avoid stepping or placing heavy objects on the
cable during installation.
Mounting the Ultrasonic Depth Sensor
Mount the ultrasonic depth sensor to the ring in the following way:
1. Slide the sensor into the grooves on the sensor mount (at the
top of the ring) from the upstream end of the mount until the
sensor contacts the backstop. The sensor cable should exit the
downstream edge of the ring. Orient the sensor with the four
transducers facing downward toward the inside of the ring
(flow surface).
