Anti-Corrosion Tuning Fork Liquid Level Switch——Optimal Choice for Sulfuric Acid Level Measurement Sulfuric acid is a highly corrosive chemical that is potentially explosive in concentrated form. It is a colourless, odourless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic. Sulfuric acid is an inorganic compound and the most important oxygen-containing acid of sulfur. Anhydrous sulfuric acid is a colorless oily liquid, and its aqueous solutions of various concentrations are usually used. The corrosivity of high concentration sulfuric acid is relatively strong. Guangzhou Chemical Plant expects to measure and control the liquid level of each sulfuric acid storage tank in the workshop, to realize high level alarm through liquid level sensor and control the liquid level in time, and also to achieve overflow protection, so as to avoid the safety accident caused by sulfuric acid tank overflow. Shenzhen Jiwei Automations Ltd.

The sulfuric acid stored in the chemical plant has high concentration, strong corrosivity and strong irritation, which can cause burns and carbonization of skin and flesh. If reacts with other substances may cause fire outbreak or explosion; if contacts with metal, combustible gas will be produced; and when mixed with water, a large amount of heat will be released. If high-level measurement is not accurate and results in overflow, not only results in polluting the environment, but also threatening the property and personal safety. For 60% concentrated sulfuric acid, 316L + coating material is...

cracking, so the whole instrument has the characteristics of stronger corrosion resistance and longer service life. Specifically, Ring-11 series Tuning Fork Liquid Level Switch has the following advantages: ● With only 40mm fork length, specially designed for pipelines and other applications with constricted space. Shenzhen Jiwei Automations Ltd.

● High sensitivity due to the precisely pre-adjusted harmonic resonant frequency of the fork, the lowest measurable medium density can be as low as 0.5g/cｍ³ . ● With strong disturbance resistance ability, not influenced by foam, bubbles, viscosity, vibration and other liquid characteristics. ● Industry-leading performance for high temperature working environment. Process temperature can reach up to 250℃. ● Three optional output methods: relay output, two-wire system and Namur. ● Optional air-tight high pressure protection insulation sleeve, special for pressurized or corrosive liquids level measurement....
