Micropilot FMR52 Radar Level Transmitter

Overview

The Micropilot FMR52 is Endress+Hauser’s radar level transmitter designed for applications in aggressive liquids, offering extraordinary advantages with its completely PTFE-filled and flush-mounted horn antenna. The FMR52 also serves as the sensor of choice for hygiene-sensitive applications in the food and life sciences industry, carrying ASME BPE, USP Class VI, 3-A, and EHEDG approvals.

As an authorized supplier of Endress+Hauser instrumentation, Seven Star LLC proudly offers the Micropilot FMR52 to chemical processing, food and beverage, and pharmaceutical facilities across the Sultanate of Oman, Muscat, and the wider GCC. Micropilot is used for continuous, non-contact level measurement of liquids, pastes, and slurries, with measurement unaffected by changing media, temperature changes, gas blankets, or vapors.

Measurement Principle

The Micropilot FMR52 operates as a downward-looking time-of-flight (ToF) measuring system: radar impulses are emitted by the antenna, reflected off the product surface, and received again by the radar system, with the distance from the reference point (process connection) to the product surface computed from the time delay. Operating in the K-band at approximately 26GHz, the FMR52 achieves ±2mm accuracy across a maximum measuring range of 40m (131 ft), extending to 60m (197 ft) in extended configurations.

The flush-mounted, PTFE-encapsulated horn antenna design eliminates crevices or protrusions into the process, making it ideally suited to aggressive, corrosive, or hygienic media where a conventional metallic antenna would be unsuitable. The measurement remains reliable even in the presence of gas blankets, vapor layers, and changing dielectric properties, thanks to Multi-Echo Tracking evaluation.

Engineering Design of the Micropilot FMR52

The Micropilot FMR52 operates across a process temperature range of -196°C to +200°C (-321°F to +392°F) and a pressure range of -1 to 25 bar (-14.5 to 362 psi), with hardware and software developed according to IEC 61508 up to SIL3 in homogeneous redundancy. HistoROM data management provides fast and easy commissioning, maintenance, and diagnostics, while Heartbeat Technology supports cost-effective and safe plant operation across the entire instrument life cycle.

The transmitter is available with a dual-compartment housing in either plastic PBT or 316L stainless steel construction, with 2-wire 4-20mA HART output as standard and optional Bluetooth remote access via the SmartBlue app. A 4-line SD02 display with push buttons and data backup function supports local operation, and seamless integration into control or asset management systems is achieved through an intuitive, menu-guided operation concept.
