It’s all in the price! A new Bluetooth radar level sensor for the water sector

The  new VEGAPULS WL S 61 contactless radar sensor is an ideal solution for applications in the water and sewage sectors. Its very competitive price combines with globally-proven success and comprehensive features to deliver a compelling radar based level sensor.

Radar technology offers numerous advantages when compared with ultrasonic level sensors; radar is independent of weather influence: strong sun, wind, surface turbulence, condensation, fog or rain. In addition, no compensation is needed for signal transmission time due to air temperature fluctuations. Water radar sensors are ideal for level control and flow measurement in water treatment plants. The excellent focusing enables their use in sewage pumping stations, rainwater overflow basins, digesters, sludge tanks, open channel flow measurement and for open water level gauging too.

As a compact, loop powered sensor with an accuracy of +/- 5 mm and range up to 8m along with its flexible mounting options, this means it can easily be installed into new or existing applications and connection to level controllers, telemetry or SCADA systems is straightforward too. The latest development stems from many years of experience of applications worldwide in the water and environmental sectors, providing ease of set up, ultimate performance reliability and protection of the environment. It joins the VEGA radar portfolio with another water radar device: VEGAPULS WL 61, which has been available for several years and now has a very large installed and working base of over 40,000 units world-wide.

Previously, cost was perceived as an issue with radar technology, but this new variant VEGAPULS WL S 61 offers a price more favourable than comparable to short range ultrasonic systems. It has a fully featured specification, performance and design optimized for use in the water-supply and sewage sectors. The housings are a robust IP 68 (2 bar), this high degree of protection also makes it suitable for applications where the sensor may be temporarily submerged, the technology is wear and maintenance-free. It complies with the latest Level Probing Radar standard (LPR): approved for open-air use without restrictions or special attachments.

Another entirely new feature is Bluetooth wireless operation from a free App via IOS or Android smartphone or tablet and/or PC with free to download PACTware when combined with a VEGA Bluetooth USB adapter; this option makes commissioning and diagnosis even simpler.

See the device at the forthcoming WWEM Exhibition in November, along with mCERTS pending radar open channel flow system and Bluetooth communications for all VEGA liquids and solids level transmitter technologies.


Excellent value and resistance to weather conditions, make VEGAPULS WL S 61 the ideal level sensor for water-supply and sewage applications.
