Ethylene oxide is toxic, flammable, and explosive – how can the liquid level be measured accurately and stably? https://exp-picture.cdn.bcebos.com/116b1ae23ea23a421ffc35a43733ec3835bbc0de.jpg?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_500 The measuring medium: Ethylene oxide is an organic compound with the chemical formula C2H4O; it is a toxic carcinogen that was previously used in the production of fungicides. Ethylene oxide is flammable and explosive, and not suitable for long-distance transportation; therefore, it has a strong regional character. It is widely used in industries such as washing, pharmaceuticals, and dyeing. It can be used as a starting material for cleaners in chemical-related industries. Under the actual operating conditions, it is necessary to measure the liquid level in the ethylene oxide horizontal tank. The level gauges that were used previously were worn out and damaged, and could not provide accurate readings of the liquid level. Ethylene oxide is flammable, explosive, and toxic, which imposes high requirements on the safety of measuring instruments; as a result of research, 4 Dinghua Electronics external-mounted level gauges were purchased in February 2019. https://exp-picture.cdn.bcebos.com/c33acc828689a1467583704df4bd4c7c35b3348b.jpg?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_500 The external level gauge produced by Dinghua Electronics enables isolated, contactless level measurement; it requires no drilling and does not come into contact with the medium, thus effectively preventing ethylene oxide leaks. Additionally, these external gauges from Dinghua Electronics come equipped with a SIL3 certification, ensuring safety and reliability. https://exp-picture.cdn.bcebos.com/359bee5e4a2379716060036c93196120a6cde3d1.jpg?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_500
