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. The FMR10 has a 4-20mA output and comes standard with Bluetooth for configuration. The FMR20 features a 4-20mA HART smart output that will allow for configuration from an optional remote display. Both offer Bluetooth configuration options. 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.
