In order to real-time control the open channel flow rate,effectively prevent the coal mine water trouble,using cut throat flume and none-touch measuring ultrasonic wave intelligent flow rate sensor to test the open channel flow rate.It shows the relationship between open channel real flow rate and water head height,as well as reduces the influence of sediment deposition to measuring,and also improves the stability of flow measuring device.The experiment showed that the uncertainty of ultrasonic wave cut throat channel flowmeter was lower than 4%,which meets the related national standards.
