[0036] As the device is provided with the isolation pipe 21 in the control box 2, and the pressure sensor 4 is installed inside the isolation pipe 21, the probability of the liquid in the detection pipe 1 entering the control box 2 through the sampling hole 22 can be reduced. Meanwhile, the existence of the isolation pipe 21 can also make the pressure sensor 4 have a larger contact area after installation, thereby improving the sealing effect near the pressure sensor 4.

Meanwhile, as the wire hole 53 which communicates the limiting section 51 and the control box 2 is arranged in the assembly pipe 5, it is also convenient for the circuit connection between the ultrasonic transducers 6 and the control module, and avoids the contact between the connecting line and the liquid in the detection pipe 1, so as to improve the protection effect of the ultrasonic transducers 6.

In addition, the blocking plug 63 is arranged at the end of the limiting section 51 away from the accommodating section, so as to block the assembled pipe 5 by means of the blocking plug 63, and further improve the protection effect of the device on the ultrasonic transducer 6.

[0041] Correspondingly, in order to improve the sealing effect near the ultrasonic transducer 6, the device can further be provided with a second sealing ring 61 inside the accommodating section. During the installation, the second sealing ring 61 should be arranged at the end of the ultrasonic transducer 6 close to the connecting section 52, so as to block the spliced gap near the ultrasonic transducer 6 by means of the second sealing ring 61.
