Flow meters help us achieve better measurement results in various fields. It is precisely because of these effects that our industrial production and daily life become more convenient and reliable. When producing this kind of flowmeter, in addition to paying attention to its service life, it must be considered whether it can achieve the corresponding measurement effect. Therefore, the selection of the lining of the sewage flowmeter is actually very particular, and it is also the key reason to ensure that this flowmeter can withstand the measurement of corrosive materials with a variety of acid, alkali and salt, so let's take a closer look at this together. The choice of the lining of the class flowmeter and its corresponding main performance.

First of all, I will introduce the most important lining material for sewage flow meters. First, polytetrafluoroethylene, which is the most chemically stable plastic, can resist boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia to the greatest extent during use, and of course it can withstand concentrated alkali and various organic The solvent is so powerful and the corrosion resistance allows this type of flowmeter to be used without worrying about the effect of measuring corrosive liquids on the measuring instrument itself. Therefore, it is also very suitable for the measurement of strong corrosive media such as concentrated acid and alkali and sanitary media. Second, polyperfluoroethylene propylene. This type of material has the same strong corrosion resistance as the PTFE just mentioned, but we can also understand its abrasion resistance and negative pressure resistance, which is higher than that of PTFE. some. Third, polyfluoroethylene. The lining of some sewage flowmeters chooses huge and ethylene materials. The applicable temperature is relatively lower than that of polytetrafluoroethylene, but the corresponding cost is also relatively low.

 

　　Therefore, some companies that need to control costs may choose to use this lining flowmeter after considering comprehensive factors and their own measurement requirements. Fourth, polychloroprene rubber is relatively good choice for the lining of some sewage flow meters, and it can also achieve the corrosion of the general low-concentration acid-base salt media, but it is not resistant to the corrosion of oxidizing media. For some water, sewage, weak abrasive mud and slurries, the measurement is more appropriate. In this way, the selection of different sewage flowmeter linings has different functions. Of course, we must consider our actual needs and budget in the selection process.
