Level Measurement

Micropilot FMR Series

Radar Level Measurement

Continuous, non-contact level measurement of liquids, pastes, and slurries. Unaffected by changing media, temperature, gas blankets or vapours.

M-class offers cost-effective 2-wire technology as an alternative to DP, floats and displacers. S-class delivers ±1mm accuracy over 40m for custody transfer (OIML R85 / API 3.1B).

• Two frequency ranges: 6 GHz and 26 GHz
• High temperature versions up to 400 °C
• Rod antenna for narrow nozzles, condensation and build-up
• SIL 2 certified (IEC 61508/61511)
• HART, PROFIBUS PA, FOUNDATION Fieldbus

Levelflex FMP Series

Guided Radar

Contact-based level measurement for challenging conditions. Works reliably with foam, turbulent surfaces, and low dielectric media.

Suitable for continuous level and interface measurement. Independent of density, conductivity, dielectric constant, temperature and dust. Rope, rod or coaxial probes available.

• Simultaneous interface and total level measurement
• Coax probes: independent of tank internals and nozzle installation
• Replaceable and shortenable probe rod and rope
• Onsite envelope curve display for diagnosis
• HART, PROFIBUS PA, FOUNDATION Fieldbus
• Approvals: ATEX, FM, CSA, TIIS, NEPSI, IECEx

Prosonic FMU Series

Ultrasonic Level Measurement

Non-contact measurement for fluids, pastes, and coarse bulk materials. Also suitable for open channel flow measurement.

Compact and remote transmitter options. Integrated temperature sensor for automatic sound velocity correction. Suitable for explosion hazardous areas (Gas-Ex, Dust-Ex).

• Measuring range up to 70m (depending on sensor)
• Linearisation function up to 32 points
• Relay outputs for automatic pump/level control
• Optional remote display up to 20m from transmitter
• HART, PROFIBUS PA, FOUNDATION Fieldbus

Liquicap M FMI51/52

Capacitive Level Measurement

Continuous level measurement in liquids. Handles vacuums and overpressure up to 100 bar, temperatures −80 to +200 °C.

No calibration necessary for media ≥100 µS/cm — factory calibrated to ordered probe length. Suitable for interface measurement between two liquids.

• SIL2 certified (IEC 61508); process-wetted materials FDA-listed
• Electronics switchable for media forming build-up
• Monitors insulation damage, rod breaking, and rope tearing
• No recalibration needed after replacing electronics
• Two-stage overvoltage protection

Deltapilot FMB/FMX Series

Hydrostatic Level Measurement

Hydrostatic pressure sensor for level, volume or mass measurement in liquids and paste media.

Suitable for process engineering, pharmaceuticals and food industries. Choice of CONTITE, ceramic or metal measuring cell with high reference accuracy ±0.1%.

• Very good reproducibility and long-term stability
• CONTITE cell: condensate and climate proofed
• HistoROM/M-DAT memory module for data integrity
• Modular family: interchangeable with Deltabar S and Cerabar S
• HART, PROFIBUS PA, FOUNDATION Fieldbus

Gammapilot FMG60

Radiometric Level Measurement

Non-contact, non-invasive measurement using scintillation detectors. Highest sensitivity with lowest source strength.

Independent of changing process conditions — pressure, temperature, viscosity, corrosion, stirrers. Over 10,000 units successfully deployed worldwide.

• External mounting: measures through vessel walls
• Level, density, interface layer measurement, or limit detection
• Lengths from 100mm (point detection) to 2000mm (continuous level)
• Active self-monitoring with ageing compensation
• Robust, vibration resistant; no special cabling required

FTL50 / FTL330

Vibronic Level Detection

Point level detection using tuning fork technology. Replaces mechanical detection where conductivity, air bubbles or build-up prevent other technologies.

Used in cleaning and filtering systems, coolant and lubricant tanks. External test option using test magnet with on-site LED display.

• SIL, Ex, and Hygienic approvals available
• Rugged stainless steel housing (316L)
• Compact construction — easy to install at difficult access points
• Build-up resistant with service-friendly plug-in connections
• No calibration required; self-monitoring
