The LVU40 series ultrasonic
transmitters are advanced
ultrasonic level measurement
sensors for liquids. These products
continue to meet demanding
applications.
The microprocessor-based
circuits provide a temperaturecompensated
signal for improved
accuracy. All models have the
ability to filter false echoes
produced by peripheral
obstructions.
Continuous level measurement can
be provided in a range of 0.3 to
18.3 m (1.0 to 60') with several
power and programmability options.
Point level can also be obtained
using a PLC (Industrial
Programmable Controller) or
one of OMEGA’s CNI process controllers.
