LST200

Ultrasonic level 
transmitter

Introduction

The LST200 is a microprocessor-
based ultrasonic level transmitter 
that transmits ultrasonic pulses in 
the direction of product surface. 
When some of the energy is 
reflected and travels back towards 
the sensor, by measuring the time 
elapsed between the initial pulse 
and the reflected one, the 
electronics can calculate the 
distance.
