Wireless Level Radar

The first truly wireless radar level transmitter.

The WLR05-2G is the first truly wireless radar level transmitter to measure water levels and fill-levels remotely. With the latest 60Ghz radar-on-chip technology the WLR05-2G is unbeatable when it comes to accuracy, reliability and versatility. This accessible radar technology immediately obsolete’s known technologies as ultrasonic level transmitters and hydrostatic loggers. It’s long battery-life, global connectivity and robust submersible housing makes this sensor ideal for use across different remote measurement applications where no infrastructure is available.
