1  Introduction

Liquid level measurement has never been easier .

LST300 is the most advanced compact level instrument 
available . With class leading accuracy and specification 
typically only found in expensive remote sensor units, LST300 
changes the way the world looks at compact ultrasonic 
transmitters .

LST300 features high temperature range, corrosion resistant 
design, metal housing, intrinsic safety, advanced diagnostics, 
false echo filtering and even real time on-screen graphic echo 
view . The LST300 can be installed in areas where compact 
instruments were never an option .

LST300 solves many liquid level challenges in liquid storage 
tanks and liquid processes in a wide range of industries, 
including:
•  Water and wastewater
•  Chemical and petrochemical
•  Power
•  Paper and pulp
•  Mining and metals
•  Food and beverage
