Endress+Hauser Levelflex FMP57: Guided Radar for High Silos and Demanding Bulk Solids

FMP57 is designed to maintain reliable measurement in dusty atmospheres, tall vessels and installations containing obstacles. Dust, filling noise, temperature layers and gas layers do not directly affect the guided radar measuring principle, provided the probe and installation are correctly selected.

Why Choose the Levelflex FMP57?

How Guided Wave Radar Works in Solids

High-frequency radar pulses travel down the rope probe. When they reach the product surface, part of the signal is reflected to the transmitter. The measured travel time is converted into level. Because the energy is guided by the probe, the instrument can work reliably even when airborne dust or filling noise would challenge some non-contact measurement methods.

Levelflex FMP57 Key Specifications

Specifications, approvals and material options depend on the selected order code. Confirm the current manufacturer documentation and installation conditions before ordering.

Typical Applications

• Powder storage silos
• Granular raw-material bins
• High silos and tall storage vessels
• Dusty filling and emptying processes
• Food ingredients, minerals, plastics and construction materials
• Bunkers, stockpiles and demanding bulk-solids inventory measurement

Installation Considerations

For best performance, place the probe away from the filling stream, internal ladders and structural members. Confirm the expected tensile load on the rope probe, especially where heavy solids, material movement or bridging may occur. The nozzle, roof structure, outlet geometry and anchoring method should be reviewed together with the maximum and minimum product levels.

FMP56 or FMP57?

Information Needed for Correct Selection

1. Material name, bulk density, particle size and dielectric constant
2. Silo height, diameter, roof and outlet geometry
3. Maximum measuring range and required dead-zone clearance
4. Filling point, internal obstacles and expected dust level
5. Estimated rope tensile load and whether anchoring is required
6. Temperature, pressure, hazardous-area and communication requirements
