Endress+Hauser 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, according to the company.
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 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 allows 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, according to the company. 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, according to the company.
