MiniWave Ultrasonic Level Transmitter

MiniWave Ultrasonic Level Transmitter

The MiniWave is a compact, loop-powered ultrasonic level transmitter for continuous measurement of liquids. As a price leader, it does not compromise on good value; and provides effortless and intuitive operation. Easy and flexible mounting combined with high chemical compatibility and 12m (40ft) measuring range makes the MiniWave suitable in multiple applications in all industries.


  • River level
  • Wet wells
  • Inlet screens
  • Tanks

Principle of Operation

The MiniWave emits an ultrasonic pulse, which is reflected from the surface of the liquid being measured. The reflected signal is processed using specially developed software to enhance the correct signal and reject false echoes.

Adaptive sensitivity control allows the unit to dynamically adjust and improve the received echoes for the best possible measurement outcome.
