Endress+Hauser TW251-G2BE5S00 | Levelflex TDR Level Transmitter, 4-20mA HART, Single Rod
Endress+Hauser TW251-G2BE5S00 Levelflex TDR level transmitter. 2-wire 4-20mA HART, single rod probe, -1...40 bar, -196...+400°C, for liquids in tanks & stilling wells.

Product Overview

The Endress+Hauser TW251-G2BE5S00​ is a 2-wire guided wave radar (TDR/TDR – Time Domain Reflectometry) level transmitter​ from the Levelflex TW251 series, designed for continuous level measurement of liquids, pastes, and interface layers​ in storage tanks, process vessels, and stilling wells. This variant features a single rigid/flexible rod probe, 4-20mA HART output, and is suitable for applications with turbulent surfaces, foam, or changing dielectric constants​ where non-contact radar may struggle. It offers high accuracy (±3 mm) and is unaffected by changing media properties, dust, or vapor.

Key Features

  • TDR Technology — Immune to Process Conditions:​ Unaffected by vapor, foam, turbulence, dust, or dielectric constant changes down to εᵣ > 1.4 — outperforms free-space radar in challenging tank conditions.
  • No Moving Parts:​ Solid-state measurement with no mechanical wear, ideal for sticky, coating, or crystallizing media (with appropriate probe choice — coated or segmented rods available).
  • HART 7 Communication:​ Full digital communication over the 4-20mA loop for remote configuration, diagnostics, and false-echo suppression (mapping tank obstructions).
  • Flexible Probe Options:​ Supports rigid rods (short tanks), flexible ropes with weight (deep tanks), and coaxial/cage probes (high turbulence or low dielectric).

Applications

  • Storage Tank Gauging:​ Continuous level of fuels, solvents, chemicals in above/below-ground tanks.
  • Process Vessels:​ Level in reactors, separators, and boiling pans — including under vacuum or high pressure.
  • Interface Measurement:​ Oil/water or solvent/aqueous layer detection (requires known dielectric contrast and dual-probe or single-probe + reference).
  • Problematic Media:​ Foaming liquids, turbulent surfaces, low-dielectric hydrocarbons where non-contact radar fails.
Note: The exact probe length, process connection (flange rating/size), and seal material are defined by the full 5th–8th character group in the order code (here "G2BE5S00" represents a typical TW251 base configuration with 4-20mA HART and standard electronics). Always verify the complete type code for probe specification.
