Reliable radar level measurement !

Since the successful launch of their Micropilot radar level device more than 20 years ago, Endress+Hauser installed more than 300,000 radar instruments in a wide range of applications across the globe. They have just launched their new Micropilot FMR5x range offering more for money with improved reliability of signal analysis and a new data management system for quick and easy information sharing and replacement.

Designed for use in the process industries, the Micropilot FMR5x range includes the FMR50 (liquids) and FMR56 (solids) for use in basic applications right through to the FMR51 (liquids) and FMR57 (solids) for use in high pressure or high temperature processes.

Precise
With our innovative multi-echo tracking system, the new Micropilot range has overcome the problem of obstacles in the radar beam, for example installed instruments or heating coils, that can interfere with the signal and give false readings. This improved way of analysing signals means that obstacles are marked and tracked along with the level, guaranteeing accurate measurements to within an incredible 2mm!

Efficient
Another advantage of the new radar instrument is the HistoROM data management function that allows fast and easy commissioning, maintenance and diagnostics. As well as continuously backing-up all relevant data, it allows you to replace main electronics by hand, quickly and simply. The instrument also offers intuitive and user-friendly menu guidance, reducing the cost of training, maintenance and operation.

Safe
Safety is always a top priority at Endress+Hauser. As a result, the hardware and software of the new Micropilot were developed according to IEC 61508 and can be used in homogeneous redundancy up to SIL3. In practice this means that Micropilot always checks it's working properly and safely by continuous self-monitoring. Two instruments are used at the same measuring point and if one of the two detects an unsafe condition, the instrument changes to an alarm condition. This reduces the risk of an unsafe process condition going unnoticed. As an extra safety net, the recurring check or proof test can be easily started either by attaching an engineering tool or directly from the control room, ensuring the instrument maintains its reliability.
