Flow velocity measurement
WebThe AVFM (Area Velocity Flow Meter) will monitor flow through open channels, partially full sewer pipes and surcharged pipes. Ideal for storm-water, combined effluent, raw sewage and irrigation water. The AVFM 6.1 uses a submerged ultrasonic sensor to continuously measure both Velocity and Level in the channel. WebA flow meter is a device that measures the flow rate of a fluid. Flow meters are flow-measuring instruments used to measure the linear, nonlinear, mass, or volumetric flow rate of a gas or a liquid. Flow meters are also known as Flow Gauges or flow measurement instruments. Accurate flow measurements of gases and liquids are …
