The right side of the Venturi tube 4 is connected to the left side of the concealed pipe 5 through a connecting pipe 7. When the flow meter 3 measures the drainage flow, the water in the concealed pipe 2 and the pipe below the flow meter 3 will continuously accumulate due to the small diameter pipe section of the Venturi tube 4, forming a full pipe state, thereby reducing the measurement error of the flow meter 3.

[0039] Among them, such as Figure 5 As shown, a sealing rubber ring 12 is provided on the right side interface of the threaded connector 101. A sealing rubber ring 12 is also provided at the position where the inner wall of the threaded sleeve 9 contacts the sealing rubber ring 12 on the threaded connector 101. When the threaded connector 101 is screwed into the threaded sleeve 9, the two sealing rubber rings 12 overlap and squeeze each other to form a seal, which plays an auxiliary role in ensuring the water volume in the concealed pipe is full and prevents water leakage.

[0040] The specific usage and function of this embodiment are as follows:

[0041] In this invention, the threaded connector 101 on the right side of concealed pipe 1 is inserted into the threaded sleeve 9.
