Abstract
A method for operating an ultrasonic fluid meter, preferably an ultrasonic water meter, in a fluid distribution network, includes using an ultrasonic transducer to generate an ultrasonic signal which passes through a measurement path, and determining a flow volume by using evaluation electronics on the basis of a transit time and/or a transit time difference of the ultrasonic signal. A hydraulic force change acting on the ultrasonic transducer through the fluid generates a voltage signal waveform on the ultrasonic transducer and the voltage signal waveform is tapped by the evaluation electronics. An ultrasonic fluid meter, preferably ultrasonic water meter, is also provided.
