DESCRIPTION AND OPERATION

LVU10 SERIES ULTRASONIC LEVEL TRANSMITTER.

INSTRUCTION

SHEET

The LVU10 series is a continuous non-contact level transmitter and distance measuring device. It
measures level or distance using ultrasonic (acoustic-sound) energy. Thr oughout this manual we will
reference the device for use as a level instrument, although it is equally suited for distance in applications
like collision avoidance or paper roll filling. The sensor is mounted in the top of a vessel pointing down at
the liquid or slurry. A sound wave (beam of
sound energy) is transmitted at the surface and
reflected by it. This "echo" is processed using
Gaussian Signal Averaging and is automatically
temperature compensated providing an analog
output (4-20 mA) proportional to the level.
The factory preset output cannot be adjusted
providing a calibration free, "plug-and-play"
level sensor for use in most liquids and slurries
that do not foam heavily. To rescale (if
required) the two-wir e output, simply take it
into a panel meter, DCS, PLC, SCADA or R TU
and use the receiving devices’ scaling features.
The LVU10 is a cost competitive, DC powered,
corrosion resistant, fixed output transmitter. If
you need more versatility, contact closures,
high temperature operation, or any other
feature that the LVU10 does not have, please
contact Omega.
You also may want to consider purchasing a
high or low level alarm for use
with your LL 395. These switches can greatly
improve your pr ocess and pr ovide additional
security by giving you a redundant (back-up)
overflow or pr oduct loss signal.
