The LST300 is a high performance ultrasonic level transmitter that accurately measures level, distance and open channel flow in ranges up to 10m (30ft). It is a non-contact, level measuring instrument designed for use on liquid level in a wide range of applications and industries.","LST300 represents the future of level measurement. While using intelligent compact transmitters has always been attractive, certain limitations prevented their use in many applications. LST300 removes those old obstacles. Whether you have the risk of flooding or corrosive materials in the process, LST300 survive these conditions easily. With metal at the top and PVDF at the bottom, LST300 is the first compact ultrasonic to be resistant to corrosion on the entire instrument. Ingress protection approvals up to IP68 (optional) ensure the entire device can survive flooding.","LST300 combines the most advanced functions found on any ultrasonic in any class, in a compact form. Installation becomes easy thanks to the graphic echo display and advanced diagnostics. The false echo filtering algorithm combined with the best-in-class beam angle ensures easy installation in narrow areas with many obstructions. With through the glass technology, you never have to open the cover to configure the instrument. It is hard to believe that all this functionality is available on a device powered by only two-wire loop power.","FEATURES:","OPTIONS:","— Through the Glass (TTG) buttons, standard push buttons or without HMI interface","— 6 m (20 ft.) or 10 m (32 ft.) measurement range","— FM, ATEX, IECEx or NEPSI approved, intrinsically safe or non-sparking","— Standard, extendable or floor mounted brackets available for easy installation","— Flange mounting options
