Endress+Hauser is a global leader in measurement instrumentation, services, and solutions for industrial process engineering. As Endress+Hauser’s Mid-Atlantic representative, Eastern Controls works with Endress+Hauser to provide process solutions for flow, level, pressure, analytics, temperature, recording, and digital communications, optimizing processes’ economic efficiency, safety, and environmental impact. One such solution is Endress+Hauser’s Micropilot FMR62 for level measurement.

What is the Micropilot FMR62?

Endress+Hauser’s Micropilot FMR62 is the first 80GHz radar developed according to the international functional safety directive IEC 61508. The FMR62 is for level measurement in aggressive liquids or applications with hygiene requirements. For applications in aggressive liquids, FMR62 offers a multitude of advantages, including the implementation of Multi-Echo Tracking.

Multi-Echo Tracking

The traditional Time-of-Flight method uses an echo signal curve, which not only measures the level of the tank but also measures any obstacles within the vessel (tank). A mapping functionality is used to exclude any of these obstacles when measuring the true level. The problem with this method is if the initial level is below the mapping, jumps or drops in the level may occur which will read an error – therefore decreasing its reliability.

Endress+Hauser’s Multi-Echo Tracking technology, however, leads to stable and safe signals by marking and tracking all echo signals – not just the level signal! Obstructions? Doesn’t matter. Multi-Echo tracking guarantees safe and precise measurement even with obstacles in the vessel.

How Does This Benefit You?

So, you know what the FMR62 is, but why should you consider using it within your process? Well, if you’re experiencing product losses due to inaccurate level measurements, you should definitely consider the FMR62!

With its 80GHz technology, you’re able to take advantage of its 3-degree beam angle, leading to an improved signal focus. You can profit from more reliable and accurate measurements in tanks with many obstacles with an accuracy of ± 1mm (0.04 in).

Other benefits include:

  • Hardware and software developed according to IEC 61508 up to SIL3 homogeneous redundancy
  • Heartbeat Technology for cost-effective and safe plant operation during the entire life cycle
  • HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
  • PTFE-filled and flush-mounted antenna for maximum system availability allowing for very small process connections
  • Highest reliability even with obstructions in vessels due to a small beam angle and Multi-Echo Tracking evaluation
