In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Because static pressure input level gauge is when detecting, generally directly drops into in the liquid, but along with the flow of liquid, the sensor part can appear the swing thereupon, and the testing result can consequently appear undulant, long-time operation back, if there is sediment impurity at the liquid bottom, also can block up the sensor part, seriously influences the testing result accuracy of level gauge. Therefore, as shown in fig. 1 to 3, the utility model provides a static pressure input type liquid level meter mounting structure, which comprises a liquid level meter accommodating pipe 1, wherein the liquid level meter accommodating pipe 1 can be made of a galvanized steel pipe of DN50, the length of the liquid level meter accommodating pipe 1 can be determined according to the length of a cable between a sensor of a liquid level meter and a transmitter, two ends of the liquid level meter accommodating pipe 1 are opened, the liquid level meter is placed in the liquid level meter accommodating pipe 1, a plurality of groups of circulation holes 2 are formed in the side wall of the liquid level meter accommodating pipe 1, the circulation holes 2 are axially arranged along the liquid level meter accommodating pipe 1 at intervals, the interval distances of two adjacent groups of circulation holes 2 are the same, and the interval distances between the two adjacent groups of circulation holes 2 can be uniformly adjusted according to the actually measured liquid level height, and are generally 20cm at intervals. In some special application scenarios, the spacing can be set at different intervals.

Contain four at least opening 2 in every group opening 2, and the quantity of opening 2 in every group opening 2 is the even number, and each opening 2 holds pipe 1 circumference evenly to set up along the level gauge in every group opening 2, and all openings 2 hold pipe 1 axial at the level gauge and cover the level gauge sense terminal, and the quantity of every group opening 2 is the even number, guarantees that liquid can pass through the unobstructed circulation of opening 2.
