In the actual use process, the casing 2 can be non-detachably connected to the flowmeter main body 1 or detachably connected to the flowmeter main body 1. In this embodiment, the casing 2 is detachably connected to the flowmeter main body 1 in order to be more convenient to install and easy to replace after the casing 2 is damaged. In addition, the digital display device 3 is rotatably connected to the casing 2, therefore, after the flowmeter main body 1 and the casing 2 are installed, the numerical value of the flowmeter main body 1 can be read by the digital display device 3, and the numerical value of the digital display device 3 can be aligned with and face to a working personnel by rotating the digital display device 3, which is convenient for working personnel to read and record the numerical value. In general, the reading direction of the digital display device 3 can be adjusted by using the flowmeter which is convenient for reading the numerical value.

Through the design of the above structure, the adjusting member 31 and the limiting ring 32 can not only be rotatably connected in the casing 2, but also can prevent the two components from falling off the casing 2. When the casing 2 is composed of the upper casing 201 and the lower casing 202 and the adjusting member 31 and the limiting ring 32 are detachably connected, it is also possible to replace the damaged adjusting element 31 or the limiting ring 32.

According to the above scheme, the limiting protrusion 51 in a natural state is positioned in the limiting groove 52, and then the adjusting member 31 is rotated when the numerical direction is adjusted, and the limiting ring 32 rotates along with the adjusting member 31. Because at least one of the limiting ring 32 and the annular protrusion 4 is made of an elastic material, at least one of the limiting ring 32 and the annular protrusion 4 is elastically deformed, such that the limiting protrusion 51 on the limiting ring 32 can be disengaged from the limiting groove 52 on the annular protrusion 4, and damps the rotating of the adjusting member 31. Finally, the limiting protrusion 51 is moved to the designated limiting groove 52, the adjustment of the numerical direction can be completed. In addition, the limiting groove 52 may be equally spaced in an annular array to facilitate determination of the adjustment angle.

By arranging the arc-shaped groove 321, when the adjusting member 31 rotates, the position of the limiting ring 32 corresponding to the limiting protrusion 51 is easier to deform and the deformed part is larger. When the limiting protrusion 51 moves to the next limiting groove 52, the deformed part is reset due to the elasticity of the limiting protrusion 51 and collides with the annular protrusion 4, with “click” or the like sound, thereby alerting the working personnel that the adjustment member 31 has been adjusted to a certain angle.

Through the above arrangement, the electric components in the digital display device 3 can be energized through the battery 38, and the conductive plate 37, the battery 38, the first conductive plate 391 and the second conductive plate 392 can form a closed energizing circuit. During the rotation of the regulating member 31, the first conductive plate 391 is connected with the anode conductive ring 371, the second conductive plate 392 and the cathode conductive ring 372 are connected in a contact conductive manner, so that the digital display device 3 can still maintain the closed state of the whole circuit in the rotating process, can still be continuously powered by the battery 38.
In the above embodiment, the specific materials of the first conductive plate 391 and the second conductive plate 392 are not limited. If the first conductive plate 391 and the second conductive plate 392 are made of rigid materials, the contact conduction effect can also be achieved, but abrasion will inevitably occur after long-term use, resulting in no contact between the first conductive plate 391 and the anode conductive ring 371 or between the second conductive plate 392 and the cathode conductive ring 372, so that a disconnection phenomenon is generated. In order to avoid this, in this embodiment, the first conductive plate 391 and the second conductive plate 392 are made of an elastic material, such that it can be ensured that the first conductive plate 391 is in constant contact with the anode conductive ring 371, the second conductive plate 392 is in constant contact with the cathode conductive ring 372, even if abrasion occurs at the contact portion, the circuit breaking phenomenon cannot be generated, the energy supply is more stable. In practical use, both the first conductive plate 391 and the second conductive plate 392 may be spring pieces.

Through the design of the structure, the following beneficial effects can be brought:
Thirdly, since the anode conductive ring 371 is in elastic contact with the first conductive plate 391 and the second conductive plate 392, results that the first conductive plate 391 and the second conductive plate 392 are necessarily inclined to one side. For example, the inclined directions of the first conductive plate 391 and the second conductive plate 392 are consistent with the directions when the adjusting member 31 rotates clockwise, such that when the adjusting member 31 is rotated clockwise, the inclined direction of the first conductive plate 391 and the second conductive plate 392 coincide with the direction in which the deformation occurs, results that the resistance to which the adjusting member 31 is subjected is small; while rotating the adjusting member 31 counterclockwise, the inclined direction of the first conductive plate 391 and the second conductive plate 392 is opposite to the direction in which the deformation occurs, such that the resistance to which the adjusting member 31 is subjected is large, this leads to a working personnel rotating the adjusting member 31 clockwise and counterclockwise with different forces, the hand feeling is inconsistent, inconvenient to use. In this embodiment, the first conductive plate 391 and the second conductive plate 392 are both Y-shaped, when the adjusting member 31 is rotated clockwise or counterclockwise, one inclined branch of the first conductive plate 391 and the second conductive plate 392 is relatively stressed, and the other inclined branch is stressed more, but the sum of the two forces added together is constant, this allows the adjusting member 31 to rotate clockwise or counterclockwise, the force required is the same.
