Abstract:
The invention relates to a device for measuring the level of liquid in a container by means of an ultrasonic converter, comprising an ultrasonic converter which is disposed at a distance from the base such that it radiates towards the surface of the liquid and also towards a lower reflector. The ultrasonic converter is, preferably, integrated into a housing which has a large upper opening and a small lower opening. A cavity is arranged in the base of the device below the lower opening.
