[0008] The connecting piece is arranged on the top end of the two control valves, and the detachable automatic exhaust valve is arranged on the top end of the connecting piece.

[0009] As a preferred embodiment of the present application, the bottom end of the detection tube is an inclined surface.

[0010] As a preferred embodiment of the present application, the T-shaped connecting pipe is provided with a control knob on one side.

[0011] As a preferred embodiment of the present application, the control valves on both sides of the upper end of the T-shaped connecting pipe are of opposite structures, and have the same structure and model.

[0012] As a preferred embodiment of the present application, the automatic exhaust valve is provided with an exhaust port at the top end.

[0013] As a preferred embodiment of the present application, the liquid inlet and the exhaust port are in communication.

[0014] Compared with the prior art, the present application has the following advantages: the automatic exhaust valve is arranged on the upper end of the flow meter, so that when the flow meter is inserted into the liquid for work, the bubbles will not exist in the sensor, because the bubbles will be discharged through the automatic exhaust valve, thereby making the sensor detection more accurate.
