ABB Lst300 Compact Ultrasonicr Level Transmitter
Product Description
Compact ultrasonicr level transmitter LST300
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 ultrasonicr to be resistant to corrosion on the entire instrument. Ingress protection approvals up to IP68 (optional) ensure the entire device can survive flooding.
Compact ultrasonicr level transmitter LST300
LST300 combines the most advanced functions found on any ultrasonicr 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

Application
It is designed for liquid level measurement in a wide variety of applications and industries, such as chemical, petroleum, water treatment, and food processing industries. It can be used to measure the liquid level in storage tanks, process vessels, and open channels.
Accurately measures level, distance and open channel flow within a range of up to 10m. It is a non - contact continuous level sensor, which is suitable for applications where contact - type measurement is not possible or inconvenient, such as in the case of corrosive, viscous or high - temperature liquids.
