Inlet channel
Flow-rate measurement in open channels
Process data
Measuring task:
Flow measurement
Measuring point:
Flume
Measuring range up to:
0 … 1 m
Medium:
Wastewater
Process temperature:
0 ... +40 °C
Process pressure:
0 … 0 bar
Special challenges:
Condensation, fog, wind, solar radiation
Application
Sewage and rainwater are often transported to the treatment plant in open collection channels or flumes. The flow rate is measured at various points in these channels. Measurement of the water flow at the inlet and outlet of the treatment plant is the basis for the calculation of tariffs and operating costs.
