Sensors
Ultrasonic sensor Static pressure sensor
Applications
Measurement of water flow in Effluent, Waste Water, Rivers, Canals,
Drains, Sewage, etc.
Flow Totalizer parameters
Flow measuring range: Depends on the size of the flume.
Maximum Count: 9999999999
Types of suitable weirs: Triangular weir, rectangular weir,
Parshall flume, etc.
