Long Range Depth Sensor - ADS TRITON+ Installation, Operation And Maintenance Manual

2-20 ADS TRITON+ Manual
The travel time from the sensor to the flow surface and back is
converted to distance, which translates into the depth of the flow.

Pressure Depth Sensor
A pressure transducer in the AV|Max sensor measures the depth of
the flow over the sensor. The monitor can use this data for
comparison with other depth measurement devices in less than full-
pipe conditions. The pressure depth sensor also can measure depths
greater than full pipe that may extend up into the manhole during
surcharge conditions.
Water pressure impacts a diaphragm in the transducer that varies an
electrical current. This current is digitized by a sensor processor
board and the value is sent to the monitor processor board. A vent
tube on the back of the diaphragm equalizes for atmospheric
pressure. The pressure transducers used in the AV|Max sensor is a
0 - 10 PSI (0 - 0.68 Bar).

Long Range Depth Sensor

The Long Range Depth sensor (ADS p/n 8K-CS6-C1-10) with a
standard adjustable Mounting Bar (ADS p/n 8000-0450) attaches
beneath the manhole cover and measures ultrasonic depth.
