The Micro-Wave River Velocity Portable Meter gives you precise speed measurement from a stationary position outside the body of water. This will help you gain accurate water speed measurement, designed specifically to measure streams and rivers. The Micro-Wave River Velocity Meter Portable is perfect tool for flood management applications
The Micro-Wave River Velocity Meter Portable is extremely valuable for measuring water surface velocity during high velocity flows and flood conditions where using contact measurement instruments pose a risk to safety.
