Large storage tanks are all tested in this way, but generally small liquid carbon dioxide storage tanks are not equipped with concentration detection devices, only pressure gauges. Therefore, when the concentration needs to be measured, only the pressure gauge can be observed or the air is released for detection. The accuracy of the result is low, so a detection device is needed that can be adapted to small storage tanks without increasing production costs. Utility Model Content
