Portable Doppler Open Channel Flow Meter

Portable Doppler Open Channel Flow Meter

Doppler Open Channel flow meter can be used to measure the liquid flow rate of the pipe which is partially filled with liquid.
Principle: Use Doppler frequency shift to measure the flow velocity, it is suitable for measuring the fluid which contains solid particles or bubbles, not suitable for measuring pure water.
Application scope: City pipe network, underground sewage testing, sewage treatment plants, streams and rivers testing.
