Pressure Depth Sensor
A pressure transducer in the AV|Gated 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|Gated sensor is a
0 - 10 PSI (0 - 0.68 Bar).

AV|Max Sensor

The AV|Max sensor with a standard 35-foot (10.6 m) (ADS p/n 8K-
CS9-10-35) mounts at the bottom center of the pipe and measures
ultrasonic depth, peak velocity, pressure depth, and water
temperature. The sensor leverages dual depth technology and
provides ultrasonic depth measurements to full pipe and pressure
depth measurements during surcharge conditions.
