What level gauge is used for level measurement of concentrated sulfuric acid storage tank?

What level gauge does concentrated sulfuric acid measure the liquid level? What are the special liquid level gauges for concentrated sulfuric acid? Concentrated sulfuric acid refers to an aqueous solution of pure H2SO4 with a mass fraction greater than or equal to 70%. High concentrations of sulfuric acid are extremely corrosive. High concentration of sulfuric acid is not only strong acid, but also has strong dewatering and oxidizing properties, which can cause pollution to water and soil. It is highly corrosive and irritating. Chemical concentrated sulfuric acid is usually stored in carbon steel storage tanks. Concentrated sulfuric acid will form a passivation protective film in the carbon steel storage tank, and concentrated sulfuric acid will oxidize the steel surface to form an oxide layer; because there is little moisture in the concentrated sulfuric acid, there is no free example, the oxide layer will not be oxidized and corroded again, Therefore, carbon steel storage tanks can be directly used as manufacturing materials for 80% to 100% concentrated sulfuric acid storage and transportation equipment. In order to ensure the safety of concentrated sulfuric acid storage, horizontal storage tanks are generally used, and leak-proof walls are built around the storage tanks. Especially in the long-term storage of concentrated sulfuric acid storage tanks, there may be a small amount of dilute acid on the upper surface of the liquid, which will react with iron to generate hydrogen, causing danger. Concentrated sulfuric acid level measurement usually uses contact level gauges such as magnetic float level, glass tube level gauge, and magnetic flap level gauge. The measurement results of the contact liquid level gauge are usually relatively accurate when it is initially installed, but after a long period of use, various mechanical failures are prone to occur, which will lead to serious consequences such as liquid level false alarms and affect the normal production process. The externally attached liquid level gauge developed and produced by Shaanxi Kaidi is a non-contact liquid level instrument, which can accurately measure the liquid level of various toxic substances, strong acids, strong alkalis and various pure liquids in high temperature and high pressure airtight containers. Measurement, the measurement probe is attached to the bottom of the tank to complete the measurement. It can meet the needs of pure sulfuric acid measurement. It is the first level gauge for concentrated sulfuric acid level measurement. It has the following characteristics: Non-contact measurement of sonar waves, safe and stable Wire system, easy to install and easy to debug, the magnetic probe can be measured at the bottom Multi-protocol (RS485, HART, Modbus, etc.), can be connected to DCS system, can realize remote transmission of measurement data to facilitate real-time understanding of data changes Related product links : Externally mounted liquid level gauge for concentrated sulfuric acid 31.html
