Abstract

The invention discloses a liquid level detector with a pressure stabilization device and a method of the liquid level detector. The liquid level detector is provided with a measurement opening, a connection pipe, an exhaust device, a pressure measurement device, a liquid level detection rod and a pressure stabilization barrel. The liquid level detection rod is hollow, the measurement opening is formed in one end of the liquid level detection rod, the other end of the liquid level detection rod is connected with the pressure measurement device in an airtight mode through the connection pipe, and the pressure measurement device is used for measuring air pressure in the connection pipe. The exhaust device is connected with the connection pipe and used for discharging liquid in the connection pipe. The pressure stabilization barrel covers the measurement opening, a plurality of exhaust holes are formed in the top of the pressure stabilization barrel, and a plurality of liquid inlet holes are formed in the lower portion of the pressure stabilization barrel. The liquid level detector is simple in structure, can be applied to pressure measurement and conversion of all liquids and has universal applicability; besides, the liquid level detector is easy and convenient to operate, convenient to use and capable of achieving liquid level measurement.

[0003] Traditional mechanical liquid level measurement is mostly direct measurement and reading, which is not convenient for space

It is also possible to transfer references through connecting pipes for measurement and reading, but there may be problems such as gas-water combination in the connecting pipe and unstable liquid level pressure fluctuations. If there is such a gas-water combination, it will lead to wrong and distorted data. Consequences that cause difficulty in reading and large errors

In addition, most of the current detection devices use sophisticated sensing elements or probes. If such devices are immersed in liquid for a long time, their sensitivity will gradually decrease and eventually fail.

As a result, the components are damaged, which may seriously cause the entire equipment to be overhauled or directly scrapped
