Peak Combo Sensor
Ultrasonic Depth Sensor
To provide the depth of the flow, the sensor se nds an ultrasonic
signal upward that bounces off the water surface – air interface.
The travel time fro m the s ensor to the flow surface and back is
converted to distance, which translates into the depth of the flow.
Upward ultrasonic depth signals bouncing off water surface
Pressure Depth Sensor
A pressure transducer in t he Peak Combo Sensor also measures the
depth of the flow over the sensor. The monitor can use this data for
comparison with other depth measurement devices in less tha n ful l-
pipe conditions. The pressure depth sensor also can measure dep ths
greater than full pipe that may extend up into t he manhole during
surcharge conditions.
Water pressure impacts a diaphragm in the t ransduc er that varies an
electrical current. This current is digitized by a sensor processor
