Abstract

A device (100) for monitoring a liquid in a container (10) comprises a device housing (110), a transducer unit (120) with a transducer (130), a resilient wave guide (140, 142), and a controller (150). The device housing (110) is configured to be mounted to an external surface (20) of the container (10). The transducer (130) is configured to emit sound waves or electromagnetic waves through the external surface (20) to the liquid and to receive reflections of the emitted waves at the air-liquid interface. The resilient wave guide (140, 142) has a top surface arranged to contact the transducer (130) and a bottom surface arranged to contact the external surface (20) of the container (10). The transducer unit (120) is configured to enable the transducer (130) to travel from a disengaged state to an engaged state, wherein the transducer (130) is closer to the external surface (20) when in the engaged state than when in the disengaged state. The controller (150) is operatively coupled to the transducer (130) to control the transducer (130) and to process the received reflections.
