VEGAFLEX 86
TDR sensor for continuous level and interface measurement of liquids
For the most extreme process conditions
Application area
Cable, rod or coaxial sensor. Its robust, mechanical design and the second process seal, the Second Line of Defense, protect the sensor for demanding measurement tasks. Process temperature: -196 ... 450° C; process temperature: -1 … 400 bar
The VEGAFLEX 86 level sensor measures maintenance-free all liquids under extreme pressure and temperature conditions. Even in applications with buildup, foam generation and condensation, the sensor delivers precise and reliable measured values. In saturated steam applications, a special reference probe ensures a density-independent measurement. The VEGAFLEX 86 offers an economical level and interface measurement for your application.
Your benefit
- The guided adjustment enables a simple, time-saving and reliable setup
- Shortenable probes offer a simple standardisation and highest flexibility in the planning
- Comprehensive diagnostic possibilities ensure a maintenance-free operation and hence a high plant availability

Level and interface measurement at high pressure and high temperature

The robust guided radar sensor VEGAFLEX 86 measures the level and interface of liquids at high process temperatures and pressures in tanks of all types. It operates independently of media properties such as density or dielectric constant in widely different vessels, bypasses or boilers. The robust mechanical design and second seal (second line of defense) protect the sensor while it performs demanding measurement tasks in the chemical, petrochemical, energy and oil/gas sectors, e.g.
- level and interface measurement in distillation columns
- level measurement in steam boilers
- level measurement in gas tanks (LPG)
Other applications
Oil separators
Fractionator
Steam boiler
Blowdown drums
