Guided wave radar LWT300 series ABB
Unlike traditional guided-wave radars that use device parameters requiring multiple adjustments, the LWT300 series of instruments does it for you.
The instrument uses LevelExpert™, a built-in intelligence to differentiate between the actual level and other false signals.
LevelExpert concentrates 20 years of industrial level measurement experience into an intelligent instrument made to accurately detect levels, even in the most demanding conditions.
Forget about baseline mapping and echo selection; LevelExpert knows how to find the right level through the clutter. The expert is now inside your guided-wave radar.
LWT300 series instruments cover a wide range of applications. They can meet your needs for applications up to 200 °C (392 °F) and 200 bars (2900 psi).
