Endress+Hauser Micropilot FMR10 and FMR20 non-contact radar instruments

The Micropilot FMR10 and FMR20 non-contact radar instruments are suitable for level measurement in the water and wastewater industry and other utilities. They offer Bluetooth commissioning, operation and maintenance via a mobile app. Signal curves can be shown via the app on every Bluetooth-enabled smartphone or tablet (iOS, Android).

A radar chip design with integrated radiofrequency components and a direct emission transceiver results in a compact device that will fit in limited-space applications. The full PVDF body of the device resists outdoor conditions and ensures a long sensor lifetime. Sealed wiring and fully potted electronics eliminate water ingress and allow operation under harsh environmental conditions. In hazardous areas or places difficult to reach, safe and secure wireless remote access is available via Bluetooth.

The FMR10 offers a 4–20 mA output signal with a fixed cable length of 10 m. It has a measuring range of 5 m with an accuracy of ±5 mm and an operating temperature of -40°C to +60°C. Ingress protection class is IP66/NEMA4x.

The Micropilot FMR20 can perform both level and flow measurement (with open channels or weirs via a linearisation table). It offers a 4–20 mA/HART output signal with a cable length of up to 300 m. It has a measuring range of 10 or 20 m with an accuracy of ±2 mm and an operating temperature of -40°C to +80°C. Ingress protection class is IP66/68 or NEMA4x/6P. It also has gas Ex approvals and the option of an RIA15 remote display.
