With the development of electronic

With the development of electronic technology and the improvement of people's life quality, in modern society, liquid level control is not only used in factory production, but also used in all aspects of life.A large number of products about liquid level data are needed in hotel factories and family life. Many scenarios require level data for monitoring. Among these products, SCM plays a key role, such as life tool elevator, industrial production field control instrument, CNC machine tool, etc. In particular, the use of single-chip microcomputer to reform backward equipment has the characteristics of high cost performance, long service life of equipment, and improving the degree of automation of equipment. A liquid level control is often used in modern industrial design, engineering construction and daily life. Early level control is mainly used in factories, such as large boilers in factories. In order to ensure the normal operation of the system, it is necessary to master the liquid level of the boiler in real time. The current level control has also been applied to life, such as the daily water boiling of electric water heater. When the water level reaches a certain limit or the temperature reaches the required value, it will give the corresponding prompt to tell people.
