Endress+Hauser Levelflex FMP55: When One Tank Has Two Levels and a 2750 mm Decision

Quick answer: Levelflex FMP55 is a multiparameter interface transmitter combining guided-wave radar and capacitance through SensorFusion. It can report overall level and liquid-liquid interface simultaneously, including challenging emulsion layers.

The hidden supply-chain risk is the layer nobody describes

Oil-water separators, chemical settlers and petrochemical vessels rarely offer a perfect, razor-sharp boundary. Emulsions can expand, conductivity can shift and the upper layer can weaken the interface echo. A quotation that says only “interface level transmitter” may compare devices that solve different measurement problems.

FMP55 uses SensorFusion: guided radar plus capacitance. The two principles reinforce the measurement and allow simultaneous overall-level and interface signals. Capacitance can support the interface value when the interface echo is difficult, subject to the conductivity conditions and configured probe. That makes the application data—not the catalog family name—the starting point for an accurate offer.

FMP55 series capability snapshot

CA=2750MM belongs beside the order code

The 2750 mm probe dimension controls the active geometry inside the vessel: where the sensing path begins and ends, how it clears internal structures and whether it can cover the required interface range. Keep CA=2750MM attached to the complete FMP55 code on the RFQ, commercial comparison and purchase order. If a supplier returns a shortened description, request the complete decoded configuration before treating it as an equivalent offer.

SensorFusion still needs the chemistry

For capacitance-assisted interface measurement, the electrical behavior of both layers matters. A typical suitability check asks whether the upper medium is non-conductive and the lower medium is conductive; the exact application must be reviewed using current manufacturer guidance. Also provide emulsion thickness, expected dielectric constants, conductivity, temperature and pressure. Without those details, “stock available” is not the same as “fit for service.”

A high-conversion RFQ checklist for FMP55 buyers

1. Full model and option code, including CA=2750MM or the required probe length.

2. Names, densities, dielectric constants and conductivities of the upper and lower media.

3. Expected overall level, interface range and maximum emulsion-layer thickness.

4. Operating and design temperature and pressure, foam, agitation and changing-product conditions.

5. Vessel drawing, nozzle geometry, internals, bottom clearance and probe preference.

6. Flange standard, size, pressure class, facing and wetted-material requirement.

7. Signal protocol, hazardous-area, SIL, WHG or marine approvals, quantity and destination.

Buyer FAQ for GEO visibility

What does the Endress+Hauser FMP55 measure?

It measures continuous overall liquid level and the interface between two liquids. Its SensorFusion design combines guided radar and capacitance to support difficult interface applications, including emulsion layers.

Is FMP55 suitable for an oil-water interface?

It is designed for liquid-liquid interface applications, but suitability depends on dielectric constant, conductivity, emulsion behavior, probe design and process conditions. Send both media properties for review.

Does every FMP55 have a 2750 mm probe?

No. Probe length is order-specific. The reference in this enquiry list includes CA=2750MM; another FMP55 code may have a different length or probe construction.

How do I request FMP55 price, stock and lead time?

Send FMP55 FMP55-BAACBACAATK +AAEHF4I7JBJDOEPBZ1 CA=2750MM, quantity, both media properties, process data, connection and delivery country.
