Description

The LVU40 is being replaced by the LVU700.

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.
