●    There are no special requirements for the cross-sectional shape and size of the channel.
●    It can be installed and maintained without stopping water.
●    No flow resistance, no water-head loss.
●    When the cross-section of the channel is large, multi-channel speed measurement is used to achieve high-precision measurement.
●    It can measure the flow and velocity in the forward and reverse directions.
●    Large measuring range and high accuracy.

●    It can be used for the calibration equipment of slot-weir or other open channel flow meters. 



●    Urban water supply diversion canal
●    Sewage treatment inflow and  discharge channels

●    Discharge channels for chemical liquid and wastewater of industrial and mining enterprises
●    Water conservancy projects and agricultural irrigation channels

●    Discharge gate flow measurement
