The LVU100 Series is a general  
purpose 2-wire ultrasonic transmitter. 
It provides non-contact level  
measurement up to 8 m (26'), and 
is well suited for handling ultrapure, 
corrosive, slurry or waste liquids. The 
LVU100 Series transmitter is often 
used in atmospheric bulk storage,  
day tank, waste sump, process vessel, 
IBC tote, 55-gallon drum and waste 
sump applications. Media examples 
include acetic acid and resin.
