Abstract

A measuring device has at least one ultrasonic transducer and an evaluator for evaluating a measurement signal provided by the at least one ultrasonic transducer. The evaluator is set up to determine a first comparison signal, by comparing the measurement signal with a first switching threshold, and a second comparison signal, by comparing the measurement signal with a second switching threshold which is different from the first switching threshold, and to determine a signal amplitude of the measurement signal depending on the first and second comparison signal.
