Endress+Hauser Level Flex Guided Radar Level and similar items

Endress+Hauser Level Flex Guided Radar Level Sensor PRE OWNED/ GOOD CONDITION/ UNTESTED/ WE WERE TOLD THIS WAS PULLED FROM WORKING ENVIRONMENT BUT CANNOT TEST ANY FURTHER SO WE ARE SELLING AS IS / UNKNOWN MODEL NUMBER ? What It Is The Endress+Hauser Levelflex is a guided wave radar (GWR) level transmitter used for continuous level measurement in tanks and vessels. Measurement principle: Time-of-flight radar along a probe Output: 4?20 mA + HART (Fieldbus optional) Mounting: Top-mounted (threaded or flanged) Probe types: Rod Rope (long tanks) Coaxial (best accuracy) ?? How It Works (Simple Explanation) The transmitter sends a radar pulse down a metal probe The signal reflects off the product surface Return time = level measurement ? Because the signal follows the probe, it?s: Not affected by foam, vapor, or turbulence Much more stable than non-contact radar in tough conditions ?? Key Specs (Typical Levelflex FMP51 / FMP55) Accuracy: 2 mm (very high precision) Max range: Rod: ~10 m Rope: up to ~45 m Temperature: up to ~200C (392F) Pressure: up to ~40 bar (~580 psi) Outputs: 4?20 mA HART / Foundation Fieldbus ? Key Advantages (Why People Use It) Highly reliable in difficult conditions Foam, vapor, boiling ? no problem No moving parts Works with: Liquids Slurries Interfaces (oil/water layers) Advanced diagnostics (Heartbeat Technology, echo tracking) ? Example: The Levelflex FMP55 can measure both level AND interface simultaneously using dual technology ? Best Applications Tank level (oil, chemicals, water) Interface measurement (oil/water separation) Steam drums / high-temp vessels Slurry or dirty service Tall vessels (rope probe version) ?? Limitations / Things to Check Requires probe inside tank (intrusive) Probe must be compatible with: Product (corrosion) Temperature Not ideal for: Very low dielectric fluids ( ~1.4?1.6 without coax probe) Needs proper installation clearance (avoid obstructions) SHELF: 83 SA
