The ultrasonic flowmeter 4 can perform non-contact measurement, can detect the flow condition at all times, and then observe the chemical dosing situation in the first time, and anomalies can be processed in time.

[0023] As Figure 2 、 3 shown, the shock-absorbing ring 6 includes a connection end 601 fixedly connected to a fixing piece 8 at the top of the telescopic support 5. A connection hole for connection is opened at the central position of the connection end 601. The fixing piece 8 is of a U-shaped groove structure, and a through hole matching the connection hole is opened thereon for detachably installing the shock-absorbing ring 6. An upper clamping ring 603 is hingedly connected to the left end of the lower clamping ring 602 through a hinge shaft 609 at the upper end of the connection end 601. A rotating shaft 604 is installed at one end of the lower clamping ring 602 away from the hinge shaft 609. A circular ring 605 is sleeved on the rotating shaft 604. A threaded rod 606 is integrally formed at the upper end of the circular ring 605. The threaded rod 606 passes through the upper clamping ring 603 and is connected to a wing nut 608. A gasket 607 is installed between the upper clamping ring 603 and the wing nut 608. By rotating the wing nut 608, the lower clamping ring 602 and the upper clamping ring 603 are opened and closed and fixed on the pipeline. Shock-absorbing films 610 are installed on the inner side walls of the lower clamping ring 602 and the upper clamping ring 603. When the pipeline vibrates, the shock-absorbing films 610 play a certain shock-absorbing and buffering role.

By rotating the wing bolt 705, the resisting block 704 can be moved towards the liquid outlet pipe 3 so that it abuts against the liquid outlet pipe 3, preventing the liquid outlet pipe 3 from shaking between the bottom ring 701 and the top ring 702, playing a certain shock absorption role. In addition, the resisting block 704 is made of an elastic material to avoid damaging the pipeline. An upper mounting block 706 is installed at the center position of the top of the top ring 702. A shock absorption damper 707 is installed at the upper end of the upper mounting block 706. An upper fixing piece 708 is installed at the top of the shock absorption damper 707, and the upper fixing piece 708 is fixedly connected to the wall. The shock absorption damper 707 can transmit the vibration force of the pipeline to the wall after buffering, so as to achieve the purpose of shock absorption in turn.
