Endress+Hauser Levelflex FMP50 – Reliable Guided Radar for Basic Liquid Level Applications

The Levelflex FMP50 is a guided radar level transmitter designed for continuous level measurement of liquids, pastes and slurries in basic process applications. Based on the time-of-flight guided radar principle, it provides stable and accurate measurement even when process conditions change.

Designed as a cost-effective solution for storage tanks, supply systems and utility processes, the FMP50 combines proven Endress+Hauser radar technology with simple installation and reliable operation.

Guided Radar Measurement for Stable Level Monitoring

Unlike contact measurement technologies that rely on mechanical movement, the Levelflex FMP50 measures level through electromagnetic pulses transmitted along a probe.

The guided radar signal travels along the probe and reflects from the medium surface. The measured travel time is converted into an accurate level value.

Frequently Asked Questions

What is the Endress+Hauser Levelflex FMP50 used for?

The FMP50 is used for continuous level measurement of liquids, pastes and slurries, especially in storage and utility applications.

What is the measuring range of the FMP50?

The rod probe version measures up to 4 m, while the rope probe version supports measurement up to 12 m.

Does the FMP50 measurement depend on media changes?

The guided radar measurement is designed to remain reliable despite changing media properties, temperature variations and vapor conditions.

What is the difference between guided radar and ultrasonic level measurement?

Guided radar uses electromagnetic pulses along a probe, while ultrasonic measurement uses sound waves reflected from the medium surface. Guided radar is often preferred when vapor, foam or changing conditions may affect ultrasonic signals.

Can the FMP50 be used in hazardous areas?

Yes. The FMP50 is available with international explosion protection approvals depending on configuration.

Which communication protocols are supported by the FMP50?

The FMP50 supports options including HART, PROFIBUS PA and FOUNDATION Fieldbus depending on device configuration.
