Continuous Non-Contact Radar Level Devices Utilize Bluetooth Technology

Endress+Hauser introduces the Micropilot FMR10 and FMR20 free space radar level transmitters to measure liquid levels in storage tanks, open basins, open channels, weirs and canal systems. The FMR10 measures liquid levels at ranges up to 16 ft with 0.2-in. accuracy, while the FMR20 measures levels up to 66 ft with 0.08-in. accuracy.

The FMR10 has a 4-20mA output and comes standard with Bluetooth for configuration. The SmartBlue app that runs on any Apple or Android smartphone or tablet provides secure communications with the transmitter in order to configure or view envelope curves. The encrypted and password-protected Bluetooth wireless connection allows operators to monitor the sensor’s output and perform configurations in hazardous or unsafe locations without exposing personnel to dangerous conditions. The FMR20 features a 4-20mA HART smart output that will allow for configuration from an optional remote display. It also offers the option of Bluetooth configuration, just like the FMR10. 

Protection to IP66/68 and NEMA 4X/6P, hermetically sealed wiring and fully potted electronics eliminate water ingress and allow operation under harsh environmental conditions. Both sensors are available with a flooding tube that allows a maximum output signal to be generated even if an overflow condition causes the sensor to be completely immersed.

Micropilot FMR10 and FMR20 provide an outstanding price/performance ratio. This radar technology is available in the price range of typical water and wastewater level devices. Setup is easy, with just three main parameters and a remote indicator solution, resulting in time savings and enhanced safety.
