Overview
SITRANS LG series are guided wave radar transmitters for continuous level, level and interface, and volume measurements of liquids and solids. They are unaffected by change in process conditions, high temperatures and pressures, and steam. Quick and easy setup with local four-button programming and menu-driven quick start wizard gets you operational in minutes, saving you time and money.
