Liquid level meter, is an instrument used to detect the position of liquid and demarcation position. This kind of instrument is widely used in petroleum, chemical, pharmaceutical and other industrial fields as well as production, environmental protection, transportation and other fields. Specifically, the main uses of liquid level meters include the following:

1. Determine the liquid level: Liquid level transmitter can accurately measure the height or pressure of liquid or solid powder, and according to the measurement result, we can judge the remaining amount of the substance in the container. For example, in the chemical industry, the level meter can accurately know the amount of liquid in the reactor, so as to control the process of chemical reaction.

2. Control level: the level meter is also able to control the liquid level to realize the control of the process. For example, in the petroleum industry, the level meter can be used to control the level of oil in the tank to ensure a stable supply of oil.

3. Prediction of liquid level: the level meter data can also be used to predict how much liquid is still in the liquid container. This is very useful for activities such as inventory management and planning production.

4. Monitoring liquid level: Liquid level gauge can also monitor the liquid movement status and liquid level height and other parameters, to achieve a comprehensive monitoring of the process. This is very important to ensure the safety and stability of the production process.

In addition, the level meter can also be used to measure the capacity and use of water resources and promote the overall rational use of water resources. In terms of transportation, liquid level gauge can be used to measure the vehicle oil volume, to realize the management and monitoring of vehicle oil volume.

As there are many kinds of level meters, such as magnetic flap level meter, magnetostrictive level meter, radar level meter, ultrasonic level meter, etc., it is necessary to accurately correspond to the type of level meter according to the working conditions on the site, so as to select a cost-effective, accurate measurement and long service life of the liquid level indicator.

Overall, the level meter is a very important industrial measurement instrument, which plays a key role in ensuring the safety, stability and efficiency of the production process.
