E+H Micropilot FMR43 Compact Hygienic Radar Level Transmitter

Precision Non-Contact Level Measurement for Hygienic Processes

In sanitary processing industries such as dairy, beverage, biotechnology, and pharmaceutical manufacturing, maintaining uncompromising product hygiene while securing exact level measurement is critical. The Endress+Hauser Micropilot FMR43 Non-Contact Radar Level Transmitter represents state-of-the-art radar measurement engineering. Part of E+H’s Compact Line, the FMR43 utilizes high-frequency radar signals to measure liquid inventory continuously without physical media contact, eliminating contamination risks, cleaning dead legs, and mechanical wear.

Advanced 80 GHz & 180 GHz Radar Technology for Small Vessels

Measuring levels in small vessels, buffer tanks, or mixing skids with internal agitators and heating coils has historically posed significant challenges for traditional sensors. The Micropilot FMR43 addresses this by offering both 80 GHz and ultra-high-frequency 180 GHz radar options.

The 180 GHz frequency option produces an extremely narrow signal beam angle and requires small process connections (such as G 1/2″ or small Tri-Clamp fittings). This focused radar beam avoids internal tank obstructions, vessel walls, and agitator blades, ensuring pinpoint accuracy (±1 mm) even in complex, fast-changing liquid applications or low-reflectivity media.

Certified Hygienic Design & Rugged Stainless Housing

Built specifically for strict clean-in-place (CIP) and sterilize-in-place (SIP) environments, the FMR43 features a fully sealed 316L stainless steel housing with IP66/IP68/IP69 ingress protection. All wetted materials—including PEEK and PTFE—are certified compliant with international sanitary standards such as 3-A, EHEDG, ASME BPE, USP Class VI, and FDA CFR 21 regulations.

The flush-mounted, gap-free sensor design prevents bacterial buildup and withstands extreme process thermal cycles from -40 °C to +150 °C (-40 °F to +302 °F) and process pressures from -1 to +20 bar (-14.5 to +290 psi).

Wireless Bluetooth Setup & Onboard Diagnostics

Commissioning and maintaining tank level instruments in tight skid packages is simplified with the FMR43’s integrated Bluetooth wireless technology. Plant operators can securely configure parameters, perform zero/span setup, and monitor real-time level curves using the Endress+Hauser SmartBlue app on any iOS or Android device from up to 10 meters away.

Furthermore, the device incorporates Endress+Hauser Heartbeat Technology, providing continuous internal health self-checks and traceable, audit-ready verification reports without interrupting line operations. Communication protocols include 2-wire 4 to 20 mA HART and IO-Link for digital automation integration into PLC, SCADA, or DCS architectures.

FAQ

Q1: Is the Endress+Hauser Micropilot FMR43 supplied as an authentic original unit? A: Yes. We supply 100% genuine, brand-new Endress+Hauser instruments complete with original factory serial numbers, calibration reports, and official documentation.

Q2: When should I select the 180 GHz radar frequency option over 80 GHz? A: The 180 GHz option is ideal for small vessels or skids with very small process connections (such as G 1/2″). It produces an extremely narrow beam angle that avoids internal tank agitators, spray balls, and narrow nozzle necks.

Q3: Can the FMR43 withstand aggressive CIP and SIP thermal cleaning cycles? A: Yes. The FMR43 features a fully sealed 316L housing and PEEK/PTFE wetted parts rated for continuous process temperatures up to +150 °C (+302 °F) and washdown ingress protection up to IP69K.

Q4: How can I request distributor quotes and confirm delivery lead times? A: Simply submit your required E+H model ordering code, process connection size, and process parameters through our inquiry form. Our sales team will provide a prompt, competitive quotation and export delivery timeline.
