Siemens' SITRANS LR200 is a cost-effective level measurement solution for liquid bulk storage or simple process vessels in chemical plants and tank farms. Its hermetically sealed Uni-Construction polypropylene rod antenna offers excellent chemical resistance. The antenna features an internal, integrated shield that eliminates vessel nozzle interference. SITRANS LR200 features Siemens patented Process Intelligence signal-processing technology for superior reliability.

SITRANS LR200’s unique design allows safe and simple programming using the Intrinsically Safe handheld programmer without having to open the instrument’s lid. Installation is simplified as the electronics are mounted on a rotating head that swivels, so you can line up the instrument with conduit or wiring connections or adjust the position for easy viewing.
