DESCRIPTION

The Raven Eye is the new non-contact RADAR area/velocity flowmeter for open channel flow measurements from Flow-Tronic. It combines state of the art non-contact measuring technology which measures flow from above the water surface with easy integration into existing SCADA or telemetry systems.

Radar area/velocity flow sensors have been in use for many years. Using the latest design, development and production methods, has allowed Flow-Tronic to manufacture a high quality new generation radar sensor at a price that will make it your first choice for open channel and sewer flow measurement, but affordability is only one of the Raven Eye’s benefits.

The name was not chosen at random, like the bird, the Raven Eye has three key attributes: Intelligence, Adaptability, Survivability.

The Raven Eye is mounted above the water surface and measures the flow velocity at the water surface using a pulse wave radar and the flow depth with a level sensor (ultrasonic, radar or pressure). The flow rate is calculated applying the continuity equation:
Q = V x A
