[Chemical Knowledge]:The principle of differential pressure level meter is introduced: measuring liquid level sharp instrument

Accurate measurement of liquids is essential in many industrial and laboratory applications. Liquid level measurement is one of the important technical tasks, especially in fluid control. Differential pressure level gauge is a common device for measuring liquid level, which is used to measure and monitor various media, such as steam, liquid and gas. The basic principle of

differential pressure level gauge is to use the relationship between the static pressure of the liquid and the height of the liquid level. It consists of two containers connected to the pipeline, one of which is a pressure drop container and the other is a capacity container. During the measurement process, the device is connected to two reservoirs of different heights through two identical pipes, filled with liquid, and the reservoirs are connected to the container of the differential pressure level gauge. At this time, the liquid in the reservoir causes pressure, flows through the two pipes, and generates different pressure differences. The lead-out pipe is connected to the measuring end of the differential pressure gauge, and the liquid level is measured according to the principle. The advantage of

differential pressure level gauge is that it can measure a wide range of pressures and liquid levels, and is suitable for various media, including steam, liquid and gas. The differential pressure level gauge has a simple structure, easy maintenance and low cost, does not require an external power supply, is easy to install, is not affected by electromagnetic interference, and has high reliability.

Of course, differential pressure level gauges also have limitations. Since it is based on the relationship between hydrostatic pressure and liquid level, the container and pipeline must be sealed, otherwise the measurement error will be large. As the height of the liquid level rises, the measurement error will gradually increase. In addition, changes in the density of the liquid can also affect the measurement results.

to sum up, the differential pressure level gauge is a liquid level measuring instrument with high stability, high accuracy, simple operation and moderate price, which has important value in many industrial and laboratory applications. It can quickly and accurately obtain liquid level data without considering special conditions such as temperature, density, pH, etc.
