Endress+Hauser FMR60 Series: One Family Name, Two Different Radar Level Decisions

E+H Item Picture 2 from our resource library. Verify the exact nameplate and complete order code before purchase.

A one-letter generation change can rewrite a shutdown plan

When a tank level loop becomes a shutdown bottleneck, procurement teams often search only for “FMR60.” That shortcut can hide the most important question: does the plant need the established FMR60 configuration, or has engineering approved a move to the newer FMR60B platform? A unit can share 80 GHz radar technology, a 50 m family measuring range and ±1 mm reference accuracy yet still differ in process limits, communication choices, connection options, approvals and commissioning workflow.

For a direct replacement, the safe starting point is the installed nameplate—not a family comparison chart. Send FMR60-AAALAAGAA3XJG or FMR60B-AABAEJAFBSJCRCFA+LA, then add quantity, medium, process temperature and pressure, vessel geometry, nozzle details, hazardous-area classification, output protocol, destination and delivery deadline. If a substitute is proposed, require a written deviation list before reserving stock.

FMR60 versus FMR60B: family-level sourcing comparison

Why 80 GHz matters—but does not finish the selection

Both product families use a small beam angle and strong beam focusing, which supports vessels with internal fittings and helps isolate the desired level echo. The non-contact principle is suitable for liquids, pastes and slurries and is designed to remain reliable through changes in media, temperature, gas blankets or vapor. Yet frequency alone does not decide whether an instrument fits a real tank. Nozzle geometry, dielectric behavior, buildup, agitation, foam, process limits and the required safety function still belong in the enquiry.

What a quotation-ready FMR60-series enquiry includes

1. Exact identity: full FMR60 or FMR60B order code and readable nameplate photo.

2. Process duty: medium, dielectric behavior, temperature, pressure, foam, vapor and buildup.

3. Tank geometry: measuring range, nozzle, internals, agitator and mounting clearance.

4. Integration: 4–20 mA/HART, PROFIBUS PA, Ethernet-APL or other required interface, plus power and cable details.

5. Compliance and delivery: hazardous-area/SIL requirements, documents, quantity, destination and deadline.

Buyer FAQ for GEO visibility

What is the Endress+Hauser FMR60 series?

FMR60 and FMR60B are Micropilot 80 GHz free-space radar level instruments for continuous, non-contact measurement in liquid applications, including pastes and slurries.

What is the maximum measuring range?

Both families publish a maximum measuring distance of 50 m. The usable range for a specific installation depends on the configured antenna, process conditions, vessel geometry and medium.

Can FMR60B replace FMR60 directly?

Not by model name alone. An engineering review must compare the complete order codes, process connection, wetted materials, range, pressure and temperature limits, communication, approvals and commissioning requirements.

How should I request price and stock?

Send either FMR60 FMR60-AAALAAGAA3XJG or FMR60B FMR60B-AABAEJAFBSJCRCFA+LA, plus quantity, application, destination and required delivery date.

For every item below, include the complete configuration shown—or the exact full code from your own nameplate. A short product root alone is not sufficient for final selection or quotation.

Request price, availability and lead time

Send the complete order code, quantity, tank data, destination and deadline. For replacement projects, include nameplate and installation photos so any deviation can be identified before shipment.
