An ultrasonic energy consumption power meter, the output end of the ultrasonic transducer and the current taking resistor R3 in the transducer circuit are connected to the X and Y input ends of the power meter, the power level meter is equipped with an analog multiplier, and a voltage dividing circuit is connected in front of the multiplier. The utility model can be made into an external type, that is, the power meter is independently installed in a chassis, and is connected to the connection circuit between the power generator and the transducer with a current taking resistor. The external power meter is equipped with a probe, which is connected to both ends of the tested transducer when measurement is needed. The internal power meter can be directly installed in the chassis of the ultrasonic power source.
