Micropilot FMR60 80 GHz Radar Level Transmitter

Overview

The Endress+Hauser Micropilot FMR60 is a flagship 80 GHz radar level transmitter engineered for high-confidence, non-contact level measurement in liquids, pastes and slurries. Its focused W-band beam and PTFE drip-off antenna deliver stable echoes even in vessels with internals, foam, vapors or gas blankets. With ±1 mm accuracy and up to 50 m measuring range, FMR60 fits storage tanks, day tanks, and process vessels across oil & gas, chemicals, power, water and marine. Built-in Heartbeat Technology adds verification and monitoring without process interruption; SIL-capable variants support overfill prevention and safety loops.

Key Features & Specs

• 80 GHz narrow beam for challenging vessels with mixers, ladders and nozzles; high immunity to changing media and temperature.

• Accuracy / Range: ±1 mm; up to 50 m (164 ft) measuring distance.

• Process conditions: approx. –40…+130 °C and –1…+16 bar depending on configuration.

• Antenna & wetted parts: PTFE drip-off antenna; threaded or flanged process connections (e.g., G/NPT, DN/ANSI).

• Outputs & integration: 4–20 mA + HART standard; device diagnostics and local display options.

• Functional safety & compliance: SIL options, international Ex approvals, WHG, marine approvals, 5-point linearity protocol (per option code). 

Applications

• Storage & process tanks (hydrocarbons, chemicals, water/wastewater) needing non-contact measurement and tight accuracy.

• Vessels with agitators or internal fittings where 80 GHz focusing is beneficial.

• Overfill prevention / proof testing with Heartbeat verification in safety-critical services. 

Installation Highlights

• Aim the radar through a clear sight path; use small beam angle to bypass internals.

• Select antenna size/material to suit medium and build-up risk; PTFE drip-off reduces condensation effects.

• Keep process nozzles clean/flush; verify dielectric constant when measuring low-εr media.

• Commission via HART; apply mapping/damping appropriately; log a Heartbeat baseline for future in-situ verifications.
