The liquid turbine flowmeter is a volumetric instrument that measures the total flow of liquid through a pipeline. It is mainly used to measure the cumulative flow of expensive media such as oil or other high-viscosity media. Its shell and gears are made of Ocr17N i12Mo2 stainless steel, which has the advantages of hygiene, cleanliness, acid resistance and corrosion resistance. It is widely used in occasions requiring hygiene and cleanliness such as liquid beverages, daily cosmetic liquids and medicine, as well as in the measurement of corrosive solutions in industrial sectors such as metallurgy and chemical engineering.
