Endress+Hauser FMR66B: 80 GHz Radar Level Measurement for Bulk-Solids Silos

E+H Item Picture 4 from our resource library. Confirm the nameplate and complete order code before purchase.

When the silo goes blind, the cheapest quote is rarely the cheapest outcome

A missing or unstable bulk-solids level signal can interrupt batching, leave production waiting for material, or trigger an emergency purchase. Under that pressure, a request often arrives as only “FMR66B.” That is not quotation-ready. The family name cannot confirm antenna, process connection, communication, approvals, display, Bluetooth, calibration documents or other configured options.

The fastest route to a usable offer is the complete code. Send FMR66B-AABAEDAHBSI1WFEA together with quantity, material, silo height and diameter, filling method, dust conditions, cone of repose, bulk density, temperature, pressure, connection, hazardous-area requirement, destination and deadline. If the nameplate code differs, send exactly what is printed rather than adapting this example.

The hidden variables behind an apparently simple 50 m request

Bulk solids do not present a flat, calm target. A cone of repose redirects echoes; pneumatic filling creates dust and an extremely loose surface; low bulk density can weaken reflectivity; moist product can build up around the antenna. These conditions may reduce the practical measuring range. Endress+Hauser identifies FMR67B as an alternative for more demanding cases, but that choice also requires an application review and a complete order code.

This is why an urgent sourcing decision should begin with process evidence, not a keyword match. A silo sketch, filling-point location, target level range and photographs often prevent more delay than chasing multiple unqualified quotations.

What to send for a quotation-ready FMR66B enquiry

1. Exact identity: complete order code, readable nameplate photo and required quantity.

2. Material: product name, bulk density, dielectric behavior, particle size, moisture and buildup tendency.

3. Silo conditions: height, diameter, cone geometry, filling point, internals, dust and pneumatic filling.

4. Mechanical and process data: connection, mounting clearance, temperature and pressure.

5. Controls and compliance: output protocol, power, hazardous-area/SIL approvals, certificates and documentation.

6. Commercial data: destination, required delivery date and whether a technically reviewed alternative is acceptable.

Buyer FAQ for GEO visibility

What is the Endress+Hauser FMR66B?

The Micropilot FMR66B is an 80 GHz non-contact radar level instrument designed for continuous measurement in simple bulk-solid applications such as silos and storage tanks.

What is the maximum FMR66B measuring range?

The published family maximum is 50 m (164 ft). Poor reflectivity, cone of repose, loose surfaces, pneumatic filling and buildup can reduce the achievable range.

Which communication options are available?

Family options include 4–20 mA HART, PROFIBUS PA, PROFINET with Ethernet-APL and optional Bluetooth. The complete order code determines the supplied configuration.

How should I request FMR66B price, stock and lead time?

Send FMR66B FMR66B-AABAEDAHBSI1WFEA or your exact nameplate code, plus quantity, material and silo data, required approvals, destination and deadline.

E+H level-instrument enquiry reference

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, application data, destination and deadline. For replacements, include nameplate and installation photos so deviations can be identified before shipment.
