AI Technical Summary
During use, the transducer of existing insertion ultrasonic flow meters may be damaged after long-term operation, which means that the long-distance transmission cable must be replaced together when replacing it, which increases the replacement time and cost.
The system adopts a junction box structure, which connects the transducer body to the junction box via a thread. The transducer cable is connected to the transducer body through the junction box. In case of failure, the transducer body can be replaced separately without replacing the cable.
It enables the individual replacement of the transducer body, saving replacement time and costs and improving replacement efficiency.
