BF00 balanced flow meter has made the enormous improvementto the tradition throttling gear; it has the balanced rectification dominantcharacter. Tradition throttling gear only has a circulation hole, after thethrottle, it causes the fluid to lose the perfect condition. While the balancedflow meter has many function apertures, it can make the flow field balancedrectification become the ideal fluidfurthest, thus it makes the differentialpressure type flow sensor's superioritybring into play better. The balanced flow meteris suitable nearly for all fluid measurements; it is a fluid measurementtechnology innovation. At present, the balanced flow meter has been alreadywidely applied to the fields of petroleum, chemical industry, metallurgy,electric power, natural gas, water treatment and so on.
