General description

Raven-Eye: The revolutionary flow meter!

The Raven-Eye is the new non-contact RADAR area/velocity flow meter 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, so why is the Raven-Eye so revolutionary? 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.

Firstly, Intelligence: The sensor uses radar to measure surface velocity, average velocity is calculated within the sensor by analyzing surface velocity distribution using a self-learning technology that doesn’t require theoretical modules nor site calibration. Negative effects from non-ideal flow conditions, waves, turbulence etc. are removed. The Raven-Eye is not a piece of “laboratory” equipment; it’s a fully developed system, designed for use in real world applications.

Next, Adaptability: The Raven-Eye can be used in almost any open channel location, from 10 cm upwards, with velocities from 0,15 m/s to 9 m/s. It’s ideal for retrofitting and industry standard MODBUS and analogue outputs allow easy integration with existing SCADA, PLC and telemetry networks. The Raven-Eye can also operate as a standalone system with flow and diagnostic displays, data logging and web data transfer.

Finally, Survivability: The Raven-Eye builds on years of experience measuring sewer flows, the sensor is totally sealed, no joints, seals, screws or washers are used. It’s rated to IP68 which means it withstands surcharge events and aggressive atmospheres. Internal sensors monitor and report the condition or “health” of the system.

The combination of these benefits and virtually zero maintenance requirements, give the user a very low “Cost of Ownership”.
