Multi-function Level Transmitter – LevelWizard II


isolvMulti-function Level Transmitter – LevelWizard II. Ultrasonic transducers work in conjunction with a transceiver that produces electrical pulses. A piezoelectric crystal located inside the transducer converts these pulses into ultrasonic waves that travel in the direction of the material to be measured. When the pulses hit the process material, an ultrasonic echo is reflected back towards the transducer, which converts them back into electrical pulses. This signal is analysed by the transceiver which performs the level calculation.


  • The LevelWizard II is the ideal multi-functional non contact instrument for level monitoring and control in liquid application.
  • It can be used in diverse applications including open channel flow monitoring, comprehensive pump control in wet well and differential and pen-stock control.
  • It utilises the latest software system “DATEM” (Digital Adaptive Tracking and Echo Mapping). This is an entirely new digital technique development. It gives the system an edge over others in identifying the “true target level” in the face of competing echoes from the pipes, pumps or any other obstructions.
  • One or two channel control units with up to 5 relays and isolated mA-outputs
