Cost-Effective Micropilot Free Space Radar Level Transmitters Introduced

Endress+Hauser (Switzerland) introduces 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 feet with 0.2 inch accuracy, while the FMR20 measures levels up to 66 feet with 0.08 inch 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 will provide 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 which 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/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.

The level sensors work in process temperatures of–40 to 176°F (–40 to 80°C) and process pressures of –14 to 43 psi (–1 to 3 bar), are vibration resistant, and have CSA/UL approvals.

Micropilot FMR10 and FMR20 provide the best price-performance ratio. For the first time, radar technology is available in the price range of typical water and wastewater level devices. Especially for the W&WW industry and utilities in all industries, the transmitters fit the application requirements. Easy setup with just three main parameters and a remote indicator solution result in time savings and enhanced safety.
