Q-Eye Radar MT

Pulse-Wave FFT Technology 

In some applications it is an advantage to have a non contact flow measurement. When combining both Radar and Water level transmitter into a hybrid flowmeter, they provide a revolutionary approach to open channel and sewer flow monitoring. Combined are pulse wave radar velocity sensing technology with ultrasonic pulse echo level sensing to measure open channel flows.

Versatile contact-free flow measurement

Q-Eye Radar MT is an extremely versatile flow measurement system designed for continuous operation and suitable for measurements of flows not only in rivers and open channels, but also in municipal wastewater and storm water sewers. Compact construction combined with the contact-free measurement principle enables an easy installation and use.

The ultrasonic depth sensor operates by energizing a piezoelectric transducer with an electronic pulse. This pulse creates a pressure wave that travels to the flow surface where a portion returns to the transducer. Our transmitter offers the best in liquid measurement. It is easy to install, eliminates maintenance caused by sensor fouling and your personnel do not get in contact with the fluid during installation.
