Endress+Hauser Levelflex FMP53: Guided Wave Radar for Hygienic Level Measurement

FMP53 is not simply a standard level transmitter with a sanitary fitting. The complete order code determines the process connection, probe length, wetted materials, housing, communication, approvals and documentation. Correct selection should therefore start with the process, cleaning method and regulatory requirements.

Why Choose the Levelflex FMP53?

How Guided Wave Radar Works

High-frequency radar pulses travel along the rod probe. When the signal reaches the liquid surface, part of it is reflected to the transmitter. The measured travel time is converted into level. The guided signal path helps reduce the influence of vessel geometry and difficult surface conditions.

Levelflex FMP53 Key Specifications
