1, if the medium to stainless steel and copper corrosion, the buffer can be used to isolate the tank, adding corrosion resistance of the isolated liquid. According to the nature of the test medium can be selected according to the nature of the test medium, but requires more than half a year without deterioration as well. If the common isolation liquid can not be applied, can be used for separation of fluoride and chlorine oil, but the price is very expensive, so the isolation tank to do a small, disassembly and assembly to recycle the use of fluorine oil.
2, in the general corrosive medium, if stainless steel spring tube capable of 1 ~ 2 years of corrosion, is optional for ammonia pressure table, the installation guide pipe pressure to short buffer coil switch to buffer tank, to prevent impurities clogging.
3, the diaphragm pressure gauge, there are 2 molybdenum titanium and tantalum plate, diaphragm and ballistic tube with methyl silicone oil delivery pressure and minimum range can achieve 0 ~ 100KPA. If the membrane material is not resistant to rot, a layer of F46 plus (poly perfluoro propylene) diaphragm, but sensitive instrument bottom has decreased. F46 can also be used directly as isolation diaphragm, but to pay attention to the permeability of the medium, the transfer fluid can be selected fluorine oil, you can play a dual role in isolation.
