At present, the common pharmaceutical corrosive liquids in the pharmaceutical field are methanol, isopropanol, ethyl acetate and other liquids, sulfuric acid, hydrochloric acid, sodium hydroxide lamp solution. So how to choose the right flow switch to detect the transmission of these corrosive liquids? Pharmaceutical factory in transport of sulfuric acid, hydrochloric acid, hydrofluoric acid such strong corrosive medium, protection of the pipeline is indispensable, it requires to choose the appropriate flow switch on transportation equipment, if choose undeserved can cause the machine idle, it is easy to cause accidents, resulting in loss of business property and personnel safety.
