DETAILED DESCRIPTION

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] Example: See Figure 1-3A multifunctional liquid level meter comprises a servo liquid level meter 1, the lower end of which is connected with an adjusting and measuring structure; the adjusting and measuring structure comprises: a measuring flat wire 2, a screw 3, a first threaded sleeve 4, a mounting sleeve 5, a plurality of measuring holes 6, an adjusting floating assembly, a liquid level sensor 7, a temperature sensor 8, a second threaded sleeve 9 and a counterweight 10; one end of the measuring flat wire 2 is fixedly connected to the servo liquid level meter 1. During installation, the device is first fixed at a specified position through a flange at the lower end of the servo liquid level meter 1, and the measuring flat wire 2 and the lower end structure are embedded in the tank. The length of the measuring flat wire 2 is controlled by a driving member in the servo liquid level meter 1 until the adjusting floating assembly located outside the mounting sleeve 5 is located at the upper end of the oil level, and the screw 3 is fixedly installed on the measuring flat wire 2. At the bottom end of the flat wire 2, the first threaded sleeve 4 is movably sleeved on the lower end of the screw rod 3, and the mounting sleeve 5 is fixedly mounted on the lower end of the first threaded sleeve 4. The threaded mounting method is adopted, and the maintenance and replacement efficiency can be effectively guaranteed when it is repaired and replaced. A number of measuring holes 6 are opened on the outside of the mounting sleeve 5, and the two ends of the adjusting floating assembly are respectively connected to the upper wall and the lower wall of the mounting sleeve 5. By setting the adjusting floating assembly, it can be ensured that the mounting sleeve 5 is always kept at the oil surface position, so as to measure the liquid level height of the oil surface. The liquid level sensor 7 and the temperature sensor 8 are fixedly mounted in the mounting sleeve 5. By setting the liquid level sensor 7 and the temperature sensor 8, the oil level and temperature in the tank can be measured, and it can also be adjusted according to different usage needs. The liquid level sensor 7 and the temperature sensor 8 are replaced or a density sensor is added, or an interface probe is added to the lower end of the mounting sleeve 5, so that the liquid level, density, temperature and oil-water interface of the oil can be measured. The second threaded sleeve 9 is fixedly installed at the center of the lower end of the mounting sleeve 5, and the top of the counterweight block 10 is movably embedded in the second threaded sleeve 9. The counterweight block 10 is set to keep the mounting sleeve 5 in a vertical state in the oil, so that the mounting sleeve 5 can be lowered following the changes in the page. The adjustment floating assembly includes: two mounting frames 11, four mounting threaded rods 12, four mounting blocks 13, four floating blocks 14 and four positioning nuts 15; the two mounting frames 11 are respectively installed at the upper and lower ends of the mounting sleeve 5, and the four mounting threaded rods 12 are respectively installed at the upper and lower ends of the mounting sleeve 5. The two ends of the rod 12 are respectively connected to the two mounting frames 11, the four mounting blocks 13 are respectively movably mounted on the upper ends of the four mounting threaded rods 12, the two ends of the four floating blocks 14 are respectively connected to the two ends of the four mounting blocks 13, the four positioning nuts 15 are respectively movably mounted on the upper ends of the four mounting threaded rods 12, and are respectively located at the upper ends of the four mounting blocks 13. When facing different measurement requirements, the heights of the four positioning nuts 15 on the upper ends of the four mounting threaded rods 12 can be changed. When the floating block 14 contacts the oil surface, the mounting sleeve 5 floats on the upper end of the oil surface through its own buoyancy. The mounting frame 11 is in the shape of a cross, and an operating door 16 is provided on one side of the mounting sleeve 5. An externally threaded connecting rod 17 is provided at the connection position between the top of the counterweight block 10 and the second threaded sleeve 9.
