The effectiveness of using external level gauges for measuring hydrofluoric acid

Thread Content

Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas; it is a clear, colorless, fuming corrosive liquid with a highly irritating odor. Melting point: -83.3°C, boiling point: 19.54°C, flash point: 112.2°C, density: 1.15 g/cm3. It is soluble in water and ethanol, and slightly soluble in ether. It is highly corrosive, capable of severely corroding metals, glass, and silicon-containing materials. Inhalation of vapors or contact with the skin can cause incurable burns. Hydrofluoric acid is highly corrosive, so liquid leaks must be prevented. https://bbs.hcbbs.com/forum.php?mod=image&aid=2143263&size=300x300&key=5b34c28148ffc165&nocache=yes&type=fixnone A chemical company in Sichuan is dedicated to the research and development as well as production of polyphenylene sulfide (PPS) composites, with sales across the whole country! The company rented 2 horizontal tanks for hydrogen fluoride. Since these tanks had been out of use for a long time, the level gauges on them were damaged. After consulting with a specialist in chemical instrumentation and conducting market research, the company decided to purchase one unit to be used first on Tank No. 1; if it performed well, another unit would be installed on the second tank. Finally, it was installed and put into use in November; after a month of trial use, there were no issues at all. https://bbs.hcbbs.com/forum.php?mod=image&aid=2143264&size=300x300&key=312fdad24d47b8ca&nocache=yes&type=fixnone. Performance: The external-type level gauges produced by Dinghua Electronics feature high measurement accuracy, are easy to install without the need for drilling holes, are safe to use, operate stably, and require no maintenance – which significantly reduces the need for maintenance work. These external level gauges do not come into contact with the liquid inside the tank, allowing for isolated measurement and effective prevention of liquid leakage. https://bbs.hcbbs.com/forum.php?mod=image&aid=2143265&size=300x300&key=e4c49e660c250920&nocache=yes&type=fixnone
