Method for verifying a clamp-on ultrasonic measuring device

A method for verifying a clamp-on ultrasonic measurement device, wherein the measurement device comprises:

• at least two ultrasonic transducers configured to transmit and receive ultrasonic signals;
• and
• an electronic measuring/operating circuit configured to operate the at least two ultrasonic transducers, to determine measured values of at least one measured variable, and to perform the verification, wherein the electronic measuring/operating circuit includes a memory unit,
• the method comprising:
• mounting the measurement device on a standard measuring section;
• activating a verification mode of the electronic measuring/operating circuit;
• transmitting at least one ultrasonic signal with an ultrasonic transducer of the at least two ultrasonic transducers;
• subsequently receiving the ultrasonic signal with another ultrasonic transducer of the at least two ultrasonic transducers;
• determining at least one measured value of at least one verification variable of the ultrasonic signal;
• comparing the at least one measured value with at least one specification value, stored in the memory unit, of the at least one verification variable;
• outputting a verification result;
• and
• deactivating the verification mode.
