Endress+Hauser Levelflex FMP53 – Hygienic Guided Radar for Food & Life Sciences
The Levelflex FMP53 is a hygienic guided radar level transmitter designed specifically for continuous level measurement in food, beverage and life sciences applications. Its guided radar technology provides reliable measurement even when the liquid surface is moving, foam is present, media properties change or the vessel is filled through a spray head.
The FMP53 combines hygienic construction, reliable time-of-flight measurement and advanced verification functions, making it particularly well suited to processes where cleanability, measurement reliability and product safety are critical.
Hygienic Guided Radar Measurement
The FMP53 uses the guided radar time-of-flight principle. Electromagnetic pulses travel along the rod probe and are reflected at the surface of the measured medium. The travel time is then converted into an accurate level value.
Because the signal is guided along the probe, the measurement remains highly reliable in process conditions that can challenge other level technologies.

Designed for the Highest Hygiene Requirements
The FMP53 is specifically engineered for hygienically sensitive production environments.
Its available hygienic process connections and suitable wetted materials allow integration into modern sanitary process equipment while supporting demanding cleaning requirements.
Typical applications include:
Food and beverage production
Dairy processing
Pharmaceutical manufacturing
Biotechnology
Life sciences
Hygienic storage and process tanks
The FMP53 meets hygiene requirements according to ASME BPE and USP Class VI, making it suitable for applications where equipment cleanliness and material compatibility are essential.
Reliable Measurement with Foam and Moving Surfaces
Foam, turbulence and changing product conditions can make level measurement difficult.
The Levelflex FMP53 is designed to maintain reliable measurement even with:
Moving liquid surfaces
Foam formation
Changing media
Filling through spray heads
Changing process conditions
The guided radar principle provides a stable measurement signal directly along the probe, helping maintain dependable level information during dynamic production processes.
In-Situ Verification Without Dismantling
One of the notable advantages of the FMP53 is its in-situ validation capability.
Measurement performance can be validated without removing the instrument from the process. This can help reduce maintenance effort and avoid unnecessary process interruptions, which is particularly valuable in hygienic production environments.
This approach supports more efficient verification procedures while keeping the measurement instrument installed and ready for operation.
Compact Rod Probe for Hygienic Tanks
The FMP53 uses a rod probe with a maximum measuring distance of 6 m, making it particularly suitable for hygienic vessels where a compact and robust probe configuration is preferred.
The available sanitary connections provide flexibility for integration into different tank and process piping designs.
Reliable Operation from Process to Maintenance
The FMP53 combines its hygienic construction with Endress+Hauser's digital device functions to support commissioning, verification and lifecycle management.
The instrument is available with international explosion protection certifications and can also be specified with WHG overfill prevention, SIL and hygienic certificates, depending on configuration.
A 5-point linearity protocol is also available for configurations where documented measurement performance is required.
Typical Applications
The Levelflex FMP53 is particularly suitable for:
Hygienic storage tanks
Process vessels
Dairy tanks
Food processing equipment
Pharmaceutical vessels
Biotechnology processes
Life sciences production systems
Its combination of guided radar measurement and hygienic construction makes it a strong choice where both process reliability and stringent hygiene standards are required.
