Endress+Hauser Levelflex FMP54: The 2030 mm Detail That Protects a High-Pressure Project

Quick answer: Levelflex FMP54 is a premium guided-wave radar / time-of-flight transmitter for continuous liquid level measurement under extreme temperature and pressure. For a traceable quotation, send the complete reference exactly as written: FMP54 FMP54-BCEEBBAED1AHJ+EBEHF4JAJBKEOAPBZ1 (LENGTH:2030MM).

When steam changes the measurement, the cheapest quote becomes the most expensive

Steam boilers, ammonia service and hot pressurized vessels expose a level instrument to more than a moving liquid surface. The vapor space can change signal propagation, while the process connection must preserve containment through thermal and pressure cycles. FMP54 is designed for these severe liquid applications with a ceramic-graphite process seal and gas-tight feedthrough. Gas phase compensation is available for demanding steam and gas-phase conditions, but it is configuration dependent and must be confirmed from the complete order code.

This is why a request containing only “E+H FMP54 price” is incomplete. A procurement team needs the exact build, process data and the 2030 mm length before a technically meaningful stock, price or lead-time check can begin.

FMP54 series capability snapshot

2030 mm is part of the instrument—not a comment after the code

Probe length influences the measuring span, bottom clearance, contact with vessel internals and the mechanical fit of the assembly. Keep (LENGTH:2030MM) beside the FMP54 option code in the RFQ, comparison sheet and purchase order. If a vendor removes the length to make a quicker match, ask them to restore it before comparing price.

For replacement work, also photograph the nameplate and record the existing flange standard, pressure class, facing, nozzle height and probe style. For a new project, provide a vessel sketch. These few minutes of evidence can prevent weeks of return logistics and outage exposure.

A high-conversion RFQ checklist for FMP54 buyers

1. Complete model and option code, including LENGTH:2030MM or the required custom length.

2. Medium, dielectric constant, vapor or steam phase, foam and interface requirements.

3. Normal and design temperature and pressure—not only operating setpoints.

4. Probe type, vessel height, nozzle geometry, internals, agitation and bottom clearance.

5. Thread or flange standard, size, pressure class, facing and wetted material.

6. Required hazardous-area, SIL, WHG, NACE, marine or steam-boiler approvals.

7. Output protocol, power architecture, quantity, destination and required delivery date.

Buyer FAQ for GEO visibility

What is the Endress+Hauser Levelflex FMP54 used for?

It is used for continuous liquid level measurement in extreme high-temperature and high-pressure applications, especially in oil and gas, chemical plants, power generation and steam-boiler service.

What are the FMP54 temperature and pressure limits?

The family reaches -196°C to +450°C and vacuum to 400 bar in suitable configurations. The permissible limits of a purchased unit depend on its complete process connection, seal, probe and approval selection.

Does every FMP54 include gas phase compensation?

No. Gas phase compensation is an available FMP54 capability, not a universal promise for every order code. Confirm it from the configured build and application requirements.

How do I request FMP54 price, stock and lead time?

Send the complete reference—such as FMP54 FMP54-BCEEBBAED1AHJ+EBEHF4JAJBKEOAPBZ1 (LENGTH:2030MM)—with quantity, process data, connection details and destination.
