Proven in practice

The new radar sensor VEGAPULS WL 61 was conceived especially for use in water management and is a real alternative to the commonly used ultrasonic sensors, also with regard to price. Radar technology offers considerable advantages over ultrasonics because it operates without being affected by temperature, wind, fog or rain. And the much higher accuracy of radar sensors makes a big difference in applications like flow-rate measurement in open channels, where the measuring ranges are sometimes very small.
The completely encapsulated cable and robust housing of VEGAPULS WL 61 provide a high protection rating of IP 66/68 (1 bar). Thanks to the different mounting options the sensor can be easily integrated into existing infrastructure.
VEGAPULS WL 61 is used primarily in applications where users demand high precision and reliable function and previous solutions have not fulfilled all requirements.

Whether level or flow – one sensor for all applications

One application somewhat apart from classic level measurement is level measurement of rivers. The small, light radar sensor VEGAPULS WL 61, mounted on a jib, records the level of the water contactlessly. Compared with elaborate gauging pipes, the costs of installation and maintenance are very low. And unlike non-contact measurement with ultrasonic devices, radar is not influenced by changing temperatures, solar radiation or strong gusts of wind. It measures the river level with a precision of +/-2 mm and provides early warning of impending floodwaters.
Simple mounting, fast setup and low maintenance requirements make VEGAPULS WL 61 the ideal sensor for many different applications – from level or gauge to flow-rate measurement.
