  • The LVU40 series ultrasonictransmitters are advancedultrasonic level measurementsensors for liquids. These productscontinue to meet demandingapplications.
    The microprocessor-basedcircuits provide a temperaturecompensatedsignal for improvedaccuracy. All models have theability to filter false echoesproduced by peripheralobstructions.
    Continuous level measurement canbe provided in a range of 0.3 to18.3 m (1.0 to 60') with severalpower and programmability options.Point level can also be obtainedusing a PLC (IndustrialProgrammable Controller) orone of OMEGA’s CNI process controllers.
