摘要
An ultrasonic flow sensor assembly includes an ultrasonic flow tube, a first reflector, a second reflector, a first ultrasonic transducer, a second ultrasonic transducer, a temperature sensor, and a tube section for accommodating the ultrasonic flow tube. The ultrasonic flow tube includes a water inlet for fixing the first reflector, a water outlet for fixing the temperature sensor and the for fixing the second reflector, a sound channel, a first mounting hole for fixing the first ultrasonic transducer, and a second mounting hole for fixing the second ultrasonic transducer. An entrance of the sound channel is equipped with a chamfer which can make the flow more smoothly and restrain turbulent flow. An installation groove for installing a seal ring is defined at an external sidewall of the ultrasonic flow tube. The ultrasonic flow tube is made of plastic or ceramic.
