Read： 1691 Time：18months ago Source：Transform the World with Simplicity

In many application fields, it is necessary to detect the height of the liquid level in the liquid container, such as petroleum, chemical industry, water treatment, etc. In order to ensure the normal operation of the production or processing process, the level gauge has become one of the indispensable instruments. The level meter can measure the liquid level by measuring the pressure, gravity, vibration and other parameters of the liquid. Different level gauges have their own advantages and disadvantages, and need to be selected according to the application scenario. The basic principle of

level meter is to measure the height of the liquid level by detecting the interface between the medium and the gas in the liquid. Some level gauges measure the height of the liquid level by installing a float suspended on the liquid level on the wall of the container and measuring the height of the liquid level through the relative movement of the float and the liquid level. Others calculate the height of the liquid level by measuring the pressure of the liquid on the wall of the container. The working principle of

level gauge needs to cooperate with a certain control system to realize automatic detection and control. In industrial production, the change of liquid level will directly affect the production process and product quality. Therefore, the level gauge control system must have high precision and high reliability to ensure the quality and efficiency of production.

different types of level gauges have different applications in industrial production. For example, on an oil drilling platform, the level gauge can help measure the height of the liquid level in the oil well to ensure safe operation. In the process of chemical production, the liquid level meter can be used to monitor the liquid in the reactor, and the reactants can be added or discharged at different stages to realize the control of the reaction. In addition, the level meter in water treatment, food processing, medicine and other industries have also been widely used.

In short, as an important measuring instrument, the level gauge has the characteristics of real-time monitoring, high precision and high reliability, and has a wide range of applications in industrial production and other fields. For the monitoring of liquid level in the production and processing process, the liquid level gauge has become an essential tool.
