Abstract
In a method for measuring the fill level of a fluid in a housing using an ultrasound sensor, detected multiple echoes in relation to a signal are reflected from a reference point and level echoes in relation to the signal reflected from the fluid level are evaluated in relation to their fluctuation width. The level echoes can be identified in this manner and the fill level determined from the transit times of the signals to the reference point and to the fluid level.
