OVERVIEW
A. Application:
The general-purpose ultrasonic transmitter pro-
vides non-contact level detection up to 32.8’ or 10m. The transmitter
is well suited for a wide range of corrosive, waste and slurry type
media, and is broadly selected for atmospheric bulk storage, day tank
and waste sump applications.

C. NEMA 4X Enclosure:
The NEMA 4X (IP65) enclosure has
a flip cover with two 1/2” NPT female conduit ports and an internal
terminal strip for wiring. To open the enclosure, you will need a small
small screwdriver. Insert the tool into the hole located at the top edge
of the enclosure and turn counter-clockwide. Rotate the hinged cover
up for 135° access to the faceplate screen and terminal strip.
About this Manual:
PLEASE READ THE ENTIRE MANU-
AL PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on then LVU800 Ultrasonic Level
Transmitter from OMEGA. Please refer to the part number located
on the transmitter label to verify the exact model configuration
which you have purchased.
User’s Responsibility for Safety:
OMEGA manufactures
a broad range of level sensing technologies. While each of these
sensors is designed to operate in a wide variety of applications, it is
the user’s responsibility to select a sensor model that is appropriate
for the application, install it properly, perform tests of the installed
system, and maintain all components. The failure to do so could
result in property damage or serious injury.
Proper Installation and Handling:
Only properly trained
staff should install and/or repair this product. Install the transmitter
with the Viton gasket and never overtighten the transmitter within
the fitting. Always check for leaks prior to system start-up.
Wiring and Electrical:
A supply voltage (loop power) of 12
-28 VDC is used to power the LVU800 series. The sensor circuit
should never exceed a maximum of 28 volts DC. Electrical wiring
of the sensor should be performed in accordance with all applica-
ble national, state, and local codes.
Material Compatibility:
The LVU800 series enclosure is
made of a flame retardant Polycarbonate (PC/ABS FR). The trans-
ducer is made of Polyvinylidene Fluoride (PVDF). Make sure that
the model which you have selected is chemically compatible with
the application media and it’s environment.
Enclosure:
While the transmitter housing is liquid-resistant the
LVU800 series is not designed to be operational when immersed. It
should be mounted in such a way that the enclosure and transduc-
er do not come into contact with the application media under nor-
mal operational conditions.
Make a Fail-Safe System:
Design a fail-safe system that
accommodates the possibility of transmitter and/or power failure.
OMEGA recommends the use of redundant backup systems and
alarms in addition to the primary system.
Flammable, Explosive or Hazardous Applications:
Do not use the LVU800 series of general purpose transmitters with-
in classified hazardous environments.
Warning
Always use the Viton gasket when installing the LVU800 series
transmitter in its fitting, and always connect the shield wire to
the common ground.
Handling Static-Sensitive Circuits/Devices
When handling the transmitter, the technician should follow
these guidelines to reduce any possible electrostatic charge
build-up on the technicians body and the electronic part.
1. Always touch a known good ground source before handling the
part. This should be repeated while handling the part and more
frequently after sitting down from a standing position, sliding
across the seat or walking a distance.
2. Avoid touching electrical terminals of the part unless making connections.
3. DO NOT open the unit cover until it is time to calibrate.
Before closing the enclosure, make sure that the enclosure gasket is
properly seated, and that any conduit fittings, liquid tight cable con-
nectors and/or plugs are properly installed and sealed.
