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.
