Non-Contact Velocity Meter With Water Level
The Radar Flow Velocity and Level Meter is connected directly via RS485 communication interface, providing simple, reliable, cost-saving process data with remote monitoring, calibration, configuration and diagnostic capabilities. Housing in a robust IP68 proof enclosure, 1500 N tensile strength Kevlar reinforced cable, up to 1.2 km digital data transmission, the transmitter is ideally used in water/wastewater industry.
surface water, wastewater
The sensor combines proven radar measurement technology with state-of-the-art spectral signal processing technology to provide a reliable and accurate way to measure velocity of flow.
