HYBRID SYSTEM

Hybrid Flow Measuring System

The HYBRID SYSTEM is Flow-Tronic’s solution for continuous measuring in every flow condition. The combination of a RAVEN-EYE® with a BELUGA is the perfect mix of two different technologies.

The hybrid solution from FLOW-TRONIC combines a level sensor with a non-contact RADAR (RAVEN-EYE®) and an ultrasonic Doppler (BELUGA) for the velocity, all connected to a single converter.

When it is impossible to accurately and reliably measure the flow rate under every flow conditions, a hybrid system is required.

Generally the dry weather flow rates are perfectly measured by a RAVEN-EYE® and an ultrasonic level measurement.

However both non-contact ultrasonic level and radar velocity signals need an air to water interface, which they lose as soon as the channel is under surcharge conditions, meaning that the ultrasonic level and radar velocity signals disappear.

The BELUGA Area/Velocity Doppler flowmeter combined to a pressure level sensor can take the relay of the non-contact flow measurement solution when the site to be measured is under surcharge.

The use of wetted and non-contact sensors makes it a reliable and maintenance free system. The wetted sensor, i.e. BELUGA, is usually installed higher in the channel. Therefore it is not impacted by water charged with debris and with a high turbidity. For those conditions, the non-contact radar sensor measures the flow velocity.

Wastewater Treatment Plants - Hybrid solution

Installation of a system at the inlet of a wastewater treatment plant, between regulating valves and screw pumps. The flow is therefore controlled upstream and downstream.
