PRECISION WAVE
PWRV431 Radar Velocity Meter

Radar velocity meter, also known as surface velocity meter, is a K-band non-contact measurement
radar sensor that has the function of continuously measuring the surface velocity of water in rivers,
troughs, weirs, ditches, etc. It can be used for hydrological monitoring, flood control and waterlogging
prevention,environmental protection and sewage discharge monitoring and other fields.
PWRV431 radar velocity meter adopts the advanced radar signal processing technology and has
high-precision speed measurement capabilities.It can measure river surface flow speed within an
angle range of 12°.The installation height range is 0.3~35m, and the measurement resolution is ±1mm/s,
which meets the requirements of the needs of hydrological observation stations for water surface
flow velocity observations.
