Abstract The evaluation index of ultrasonic water flow detection transducer is an important aspect for reflecting the transducer operational performance. The research details about the transducer evaluation index, evaluation index test method and performance test device were described.The performance and influence quantity test of the transducer has be done using a self-restraint transducer performance test device. The effective ways and means have be provided about ultrasonic water flow detection transducer screening, matching and quality control.
