1 / 11Micropilot FMR51 non-contact radar level transmitter with horn antenna and DN125 PN16 flange, manufactured 2019 (Germany) — new in Barmaan stock. Ex ia version for Zone 0/1, 4–20 mA HART output, ±2 mm accuracy. The photos show the actual unit in our warehouse.
The Endress+Hauser Micropilot FMR51 radar level transmitter is one of the best-known free-space radars for continuous, non-contact level measurement of liquids, pastes and slurries. The unit offered here was built in October 2019 at the Endress+Hauser factory in Maulburg, Germany, is entirely new, and is held physically in Barmaan's warehouse; every "Barmaan stock" photograph in the gallery on this page is of this specific device, and its nameplate, showing extended order code FMR51-BAACCABDA5YYY+ABEMPB and the build date 2019-10, is legible in the images.
Free-space radar operates in the K band (around 26 GHz): a microwave pulse is emitted from the horn antenna, reflects off the liquid surface, and the distance is derived from the signal's time of flight. Because there is no contact with the medium, the measurement is independent of temperature, pressure, density, and any gases or vapors above the surface. Endress+Hauser's Multi-Echo Tracking follows the true level echo even in the presence of interference echoes from agitators, heating coils or vessel walls.
Per official datasheet TI01040F, the maximum measured error of the standard version is only ±2 mm, and the measuring range extends to 40 m (or to 70 m with the Advanced Dynamics software package). This unit is supplied with a DN125 PN16 flange to EN 1092-1 in 316L; maximum working pressure is 16 bar, maximum process temperature is +150 °C, and the wetted parts are 316L, PTFE and FKM — a combination well suited to chemical and refinery applications.
This device is the intrinsically safe (Ex ia) version: per its nameplate it carries ATEX approval in class II 1G Ex ia IIC T6…T1 Ga for direct installation in Zone 0/1, with a 10.4 to 30 V DC two-wire supply and a 4–20 mA HART output. IP68/IP66 ingress protection allows installation outdoors and in harsh ambient conditions. Commissioning is performed through a step-by-step menu on the local display or over HART, and interference-echo suppression (mapping) takes only a few minutes.
The Micropilot FMR51 is a dependable choice for storage and process vessels in the oil, gas, petrochemical, chemical, water and wastewater industries — from calm storage tanks through to process vessels with agitators and turbulent surfaces.

This device is entirely new (new / unused), built in October 2019 (2019-10) at the Endress+Hauser factory in Maulburg, Germany, and is currently held physically in Barmaan's warehouse. The photographs on this page — including the device nameplate with extended order code FMR51-BAACCABDA5YYY+ABEMPB — were all taken of this very item in the Barmaan warehouse.
Radar measurement is entirely non-contact and, unlike ultrasonic or pressure-based methods, is unaffected by changes in temperature, pressure, medium density, or gases and vapors above the surface. With its horn antenna and ~26 GHz frequency, the FMR51 has been an industry standard for liquid tanks for years; ±2 mm accuracy and a range of up to 70 m (with the Advanced Dynamics package) make it suitable for most storage and process vessels.
Yes. Per its nameplate this unit is the intrinsically safe (Ex ia) version in ATEX class II 1G Ex ia IIC T6…T1 Ga and is suitable for installation in Zone 0/1. In this version its supply is 10.4 to 30 V DC and it must be powered through an intrinsically safe barrier or isolator. The safety documentation (XA) is delivered with the item.
Per its nameplate this unit has a 4–20 mA output with the HART protocol (two-wire, loop-powered) and is compatible with all common DCS/PLC systems (Siemens, ABB, Yokogawa, Emerson and others) as well as with HART calibrators and configurators. Other versions of the FMR51 family also offer PROFIBUS PA and FOUNDATION Fieldbus.
A DN125 PN16 flange to EN 1092-1 in 316L stainless steel (the flange stamp is visible in the photographs on this page). Per the nameplate the maximum working pressure (MWP) is 16 bar and the maximum process temperature is +150 °C. Wetted parts: 316L, PTFE and an FKM O-ring.
You can submit a proforma invoice request from this page; Barmaan's engineers will confirm the price and delivery terms within one working day at most. The item is in stock, so once the order is confirmed it is ready for collection or shipment with no overseas procurement lead time.
