[0025] The mounting mechanism 4 is arranged on the outer surface of the working cylinder 2, and the mounting mechanism 4 includes a slide rail 41, a slot 42, a rotating ring 43, a screw 44 and an adjusting cylinder 45. The slide rail 41 is respectively fixedly connected to the front and rear ends of the working cylinder 2, the rotating ring 43 is respectively slidably connected to the upper and lower ends of the slide rail 41, the slot 42 is evenly arranged inside the slide rail 41, and the inner wall of the rotating ring 43 is fixedly connected with symmetrically distributed clamping columns, which are all clamped with the slots 42 adjacent to each other in the transverse direction, the screw 44 is respectively fixedly connected to the front and rear ends of the rotating ring 43, and the adjusting cylinder 45 is respectively threadedly connected to the screw 44 away from the working cylinder 2. The mounting mechanism 4 further comprises a fixed shaft 46, an adjusting handle 47, a mounting plate 48 and a mounting block 49. The mounting plate 48 is respectively fixedly connected to one end of the adjusting cylinder 45 away from the center of the working cylinder 2, and the interior of the mounting plate 48 is provided with an adjusting groove. The fixed shaft 46 is evenly fixedly connected to the interior of the adjusting groove, and the adjusting handle 47 is rotatably connected to the middle of the fixed shaft 46. The mounting block 49 is respectively fixedly connected to one end of the adjusting handle 47 away from the center of the mounting plate 48, and the interior of the mounting block 49 is provided with a mounting hole 1, and a sliding rotating ring 43 is provided. The rotating ring 43 slides vertically inside the slide rail 41, and the rotating ring 43 is rotated to rotate. The vertical movement of the ring 43 drives the two laterally adjacent screw rods 44 to move vertically, thereby driving the two laterally adjacent adjusting cylinders 45 to move vertically. The vertical movement of the adjusting cylinders 45 drives the laterally adjacent mounting plates 48 to move vertically. When the mounting plates 48 move to the desired position, the sliding rotating ring 43 is stopped, and then the rotating ring 43 is rotated. The rotation of the rotating ring 43 drives the card columns to rotate, so that the card columns are all engaged with the laterally adjacent card grooves, thereby realizing the position fixing of the rotating ring 43. Then, according to the requirements of the installation environment, the adjusting cylinders 45 are rotated. Under the action of the corresponding screw rods 44, the adjusting cylinders 45 are moved away from the working The adjusting handle 47 is moved in the direction of the center of the working cylinder 2, thereby realizing that the mounting disk 48 is moved in the direction away from the center of the working cylinder 2. When the mounting disk 48 is in contact with the working plane, the adjusting handle 47 is toggled, and the adjusting handle 47 is moved in the direction of the central axis of the corresponding fixed shaft 46, thereby making the mounting block 49 corresponding to the adjusting handle 47 move in the direction away from the center of the mounting disk 48.

[0026] Wherein: the upper end of the control box 6 is rotatably connected with a box cover 7, an electronic display screen 8 is arranged inside the box cover 7, and the input end of the electronic display screen 8 is electrically connected to the output end of the single chip computer 9;

[0027] The lower ends of the working cylinder 1 and the working cylinder 2 are connected through a connecting pipe 13, the left end of the connecting pipe 13 is fixedly connected with a water inlet pipe, and a control valve 14 is arranged in the middle of the water inlet pipe.

[0028] The working principle of a double-chamber capacitance level gauge provided by the utility model is as follows: during operation, a person first slides the rotating ring 43, and the rotating ring 43 slides vertically inside the slide rail 41. The vertical movement of the rotating ring 43 drives the two laterally adjacent screw rods 44 to move vertically, thereby driving the two laterally adjacent adjusting cylinders 45 to move vertically. The vertical movement of the adjusting cylinders 45 drives the laterally adjacent mounting disks 48 to move vertically. When the mounting disks 48 move to the desired position, the person stops sliding the rotating ring 43, and then the person rotates the rotating ring 43. The rotation of the rotating ring 43 drives the clamping column to rotate, so that the clamping column is clamped with the laterally adjacent clamping groove, thereby realizing the position fixing of the rotating ring 43. Then, the person rotates the adjusting cylinder 45 according to the requirements of the installation environment. The adjusting cylinder 45 is moved in a direction away from the center of the working cylinder 2 under the action of the corresponding screw rod 44, thereby realizing the movement of the mounting disks 48 in a direction away from the center of the working cylinder 2. When the mounting disks 48 are in contact with the working plane, the person turns the adjusting handle 47. The adjusting handles 47 all move in the direction of the corresponding central axis of the fixed shaft 46, so that the mounting blocks 49 corresponding to the adjusting handles 47 all move in the direction away from the center of the mounting plate 48. When the mounting blocks 49 all move to the desired position, the personnel stop turning the adjusting handles 47, and then the personnel connect the mounting hole 1 inside the mounting block 49 with the threaded hole in the working area through the mounting bolts, thereby realizing the stable installation of the double-chamber capacitance level gauge. After the installation is stable, the personnel open the control valve 14, and the liquid enters the interior of the working cylinder 1 and the working cylinder 2. At the same time, the liquid level sensor 11 is operated through the single-chip microcomputer 9, and the liquid level probe 10 and the adjacent cylinder walls constitute the anode and cathode to realize the monitoring of the liquid level inside the working cylinder 1 and the working cylinder 2. The liquid level sensor 11 transmits the monitored liquid level information to the signal receiving end of the single-chip microcomputer 9 in real time, and then the single-chip microcomputer 9 realizes the operation of the electronic display screen 8 to display the liquid level information. At the same time, the single-chip microcomputer 9 sends the liquid level information to the external control terminal, thereby realizing the monitoring of the liquid level.

[0029] It is worth noting that the electronic display screen 8 disclosed in the above embodiments can use an OLED display screen, the single-chip microcomputer 9 can use an AMKN8612 control board, and the liquid level sensor 11 can use a DOB-Q30-ZNK liquid level sensor. The single-chip microcomputer 9 controls the operation of the electronic display screen 8 and the liquid level sensor 11 using methods commonly used in the prior art.
