Model RVM Portable Radar Wave Velocity Meter

Non-Contact Measurement, Handheld Meter, Angle Compensation

The Model RVM Portable Radar Wave Velocity Meter uses Doppler Radar technology to accurately measure surface velocity of open channel flow. The "point-and-shoot" design along with automatic vertical angle compensation provides easy to use operation. Model RVM also has user-adjustable horizontal angle compensation of 5° increments to further reduce measurement error. Flow velocity can be measured bi-directionally with user-selectable directional modes (flows away, towards, or in both directions). Model RVM features a backlit LCD that indicates flow velocity in feet per second or meters per second.

  • Portable Radar Wave Velocity Meter
