ULTRASONIC FLOW TUBE, ULTRASONIC FLOW TUBE ASSEMBLY, ULTRASONIC FLOW SENSOR AND ULTRASONIC FLOW METER

摘要

The present disclosure discloses an ultrasonic flow tube. The ultrasonic flow tube includes a water inlet, a water outlet, a sound channel, a first mounting hole for fixing a first ultrasonic transducer, and a second mounting hole for fixing a second ultrasonic transducer. The water inlet defines a first fixing room. The water outlet defines a second fixing room. An entrance and an exit are defined at opposite ends of the sound channel. The entrance 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 seal ring is configured to seal the ultrasonic flow tube and a peripheral structure of the ultrasonic flow tube. The ultrasonic flow tube is made of plastic or ceramic.
