Endress+Hauser Levelflex FMB53 Guided Radar Level Transmitter Hygienic Liquid Level Meter

Endress+Hauser FMB53 belongs to Levelflex series guided radar level transmitter, designed for continuous level measurement of liquids in hygienic industrial processes. Adopting guided wave radar measuring principle, the sensor transmits microwave pulse along the probe to detect medium surface and convert level signal into standard electrical output.
FMB53 features full sanitary design with stainless steel wetted parts, compliant with common food and pharmaceutical hygiene standards. It supports 4–20mA plus HART digital communication, optional PROFIBUS/FOUNDATION Fieldbus protocols for diverse system connection. This model works stably under fluctuating temperature, pressure and steam environment, unaffected by medium density, viscosity and tank installation condition.
Suitable for beverage, dairy, pharmaceutical, fine chemical and bio-fermentation industry sanitary tank level monitoring, with SIL2 safety certification available for safety-related application scenarios.

Product Description

1. Product Overview

Endress+Hauser FMB53 is a hygienic hydrostatic submersible level transmitter from Endress+Hauser’s Deltapilot series, specially designed for continuous hydrostatic liquid level measurement in sanitary industrial environments. It calculates liquid level by measuring hydrostatic pressure generated by liquid column above the sensing diaphragm. As liquid height changes, the corresponding hydrostatic pressure varies, and the internal high-precision pressure sensor converts pressure variation into standard electrical signal to realize real-time continuous level monitoring. Unlike radar-type level instruments, FMB53 measurement is free from foam, vapor, medium dielectric constant fluctuation and tank internal installation obstacles.

2. Structural & Sanitary Features

All wetted parts of FMB53 adopt high-quality 316L stainless steel material with polished seamless surface without dead leg, fully compatible with on-site CIP/SIP cleaning and high-temperature sterilization. Multiple hygienic process connections are optional: Tri-clamp, DIN11851, aseptic thread and sanitary flange, complying with EHEDG, 3A and FDA sanitary certification standards required by food and pharmaceutical industries. The transmitter housing reaches IP68 protection grade, fully resistant to liquid immersion, splash, moisture and workshop dust, suitable for harsh sanitary production environment. The submersible probe structure can be directly immersed into liquid medium for stable detection.

3. Electrical & Communication Configuration

Standard output: 4–20mA analog signal with superimposed HART protocol. Users can complete remote parameter configuration, range calibration and fault diagnosis via HART hand communicator or DCS control system. Optional PROFIBUS PA / FOUNDATION Fieldbus digital communication versions are available for access to automatic centralized control system. Working power supply ranges from 12VDC to 36VDC DC, matching conventional industrial site power supply specification. SIL2 functional safety certification is available for safety interlock loop level measurement occasions.

4. Measurement Performance & Working Condition

Measuring range: customizable from 0.1m up to 10m liquid column according to actual tank height;
Measurement accuracy: typical ±0.2%FS ~ ±0.5%FS;
Process medium temperature: -20℃ ~ +150℃, supports short-time high temperature SIP sterilization;
Process pressure: from atmospheric pressure up to 25bar;
Measuring result keeps stable regardless of changes in medium density, viscosity and suspended solids inside liquid.

5. Application Industries

Mainly used for sanitary level measurement in food & beverage, dairy, pharmaceutical, bio-fermentation, edible oil, cosmetics and fine chemical industries. Typical application: mixing tank, fermentation tank, storage tank, aseptic reactor for raw material liquid, syrup, fermentation liquid, medicinal solvent and edible liquid.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
