 Endress+Hauser Radar level:  Micropilot M FMR240
Product description
E+H Continuous and non-contact level measurement.
Cost-effective 4 to 20 mA 2-wire technology. Suitable for hazardous locations.

Your benefits
2-wire technology, low price:
A real alternative to differential pressure, floats and displacers.
2-wire technology reduces wiring costs and allows easy implementation into existing systems.
Non-contact measurement:
Measurement is almost independent from product properties.
Easy on-site operation via menu-driven alphanumeric display.
Easy commissioning, documentation and diagnostics via Endress+Hauser operating software.
Frequency range - in the K-band.
HART or PROFIBUS PA respectively FOUNDATION Fieldbus protocol.
Used for level monitoring (MIN, MAX) up to SIL 2 
as per IEC 61508/IEC 61511-1.
Option: gas-tight feedthrough to improve the process safety.

Field of application
The Micropilot M is used for continuous, non-contact level measurement of liquids, pastes, slurries, and solids. The measurement is not affected by changing media, temperature changes, gas blankets or vapors.
The FMR240 with the small 40 mm (1½") horn antenna is ideally suited for small vessels. Additionally, it provides an accuracy of ±3 mm (±0.12 in).
