Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, in particular to a buoyancy type liquid level gauge. Background Art

[0002] Liquid level refers to the height of the liquid medium in the container, and the liquid level meter is an instrument used to measure the liquid level of the medium. Liquid level meters are widely used in various fields such as electricity, pharmaceuticals, and chemicals. They are one of the common measuring instruments. The measurement objects of liquid level meters are mostly liquid media. According to the different properties of the measurement objects and the measurement methods, liquid level meters can also be divided into many types.

[0003] Authorization announcement number CN212645836U discloses a buoyancy type liquid level gauge. This patented technology is limited by the first annular groove and the second annular groove. During the process of tightening the liquid level gauge thread, part of the gasket will be pressed into the first annular groove and the second annular groove, and then the sealing gasket will be pressed tighter, thereby avoiding the occurrence of leakage and making the measurement effect more accurate; however, in this scheme, the buoyancy type liquid level gauge is in direct contact with the medium and cannot measure viscous media, which can easily lead to the liquid level gauge not working properly. At present, water pools and water towers are generally located in high positions such as roofs. Management personnel can only go to the site to observe the water level first, and then go to the control room to control the water replenishment or stop the water replenishment, which is very troublesome. For industrial water pools, machine room sewage pools, etc., they often have to be equipped with full-time on-duty personnel due to a simple water level problem. Therefore, a buoyancy type liquid level gauge is needed to improve the above problems. Utility Model Content
