The technical scheme of the utility model is: a plug-in flowmeter mounting seat, which includes a pipe and a mounting seat. There is an inverted T-shaped hole pin, the lower end of the hole pin is fixed to the inner surface of the pipeline, the upper end of the hole pin is fixed to the mounting seat, and the hole pin is provided with a detection hole connected with the pipeline. The hole pin not only connects the inside and outside of the pipeline, but also connects the installation seat and the pipeline. The structure is simple and reasonable, and the deformation of the welding between the installation seat and the pipeline is eliminated.

Preferably, the mounting base is provided with a stepped hole, and the upper part of the hole pin is inserted into the stepped hole and fixed with the mounting base through a nut; it is convenient for installation, selection and maintenance of the mounting base.

Preferably, a tile-shaped gasket is provided between the pipe and the mounting seat; the connection is reliable and sealed.

Preferably, the mounting seat is provided with an upper sealing gasket, which is ㄇ-shaped in cross-section, and the upper sealing gasket is embedded in the stepped hole; it is convenient for the mounting seat to be connected to the plug-in flowmeter to ensure that the probe is inserted into the detection hole and sealed.

Compared with the prior art, the utility model has the advantages of simple and reasonable structure and low manufacturing cost. The connection between the mounting seat and the pipeline is firm, the seal is reliable, and the insertion type flowmeter is easy to install and adjust.
