V Notch Weir Flow Measurement

We have made these from 12 gauge galvanized sheet metal and cut the metal to fit over the opening of 3 and 4 culverts.

V notch weir flow measurement. V notch weir and flume applications are widespread and typically employ a non contact ultrasonic level controller with integrated rating equations to provide level to flow calculations. Flow measurement flow metering principles orifice venturi flow nozzles pitot tubes target variable area positive displacement turbine vortex electromagnetic ultrasonic doppler ultrasonic time of travel mass coriolis mass thermal weir v notch flume parshall and sluice gate flow meters and more. Venturi meter the venturi meter is a device for measuring discharge in a pipe. V notch weir triangular weir flow design calculations software.

Introduction a weir is an opening in the sidewall of a tank at top. V notches weirs flumes. Flow measurement flow metering principles orifice venturi flow nozzles pitot tubes target variable area positive displacement turbine vortex electromagnetic ultrasonic doppler ultrasonic time of travel mass coriolis mass thermal weir v notch flume parshall and sluice gate flow meters and more. Es classes have made a number of v notch weirs to measure stream flows.

A weir w ɪər or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. The stream of liquid coming out the weir is known as a nappe sheet or vein. Units in rectangular weir calculation. 4 drawback that it is liable to block easily particularly if there is significant debris in the flow.
