Application SITRANS LR250 includes a graphical local user interface (LUI) that improves setup and operation by including an intuitive Quick Start Wizard, and echo profile displays for diagnostic sup- port. Startup is easy using the Quick Start wizard with a few pa- rameters required for basic operation. The 25 GHz frequency creates a narrow, focused beam allowing for smaller horn options and decreasing sensitivity to obstruc-tions. SITRANS LR250’s unique design allows safe and simple pro-gramming using the Intrinsically Safe handheld programmer without having to open the instrument’s lid. SITRANS LR250 measures superbly on low dielectric media, and in small vessels, as well as tall and narrow vessels.•Key Applications: liquid bulk storage tanks suppliers, process vessels with agitators, vaporous liquids, high temperatures, low di-electric media
