摘要
通常某一种流量计设计总是针对某一种特定的液体体积进行计量的,例如水表是用来计量自来水体积的,汽油表是计量汽油体积的,柴油表是用来计量柴油体积的。除了分类使用的要求之外,在技术层面的原因在于不同液体的黏滞系数不同,所以用水表计量油的体积显然是不准确的。但在某些特殊的场合,需要便捷的测量出多种不同液体的体积时,传统的流量计是无能为力的。基于此,先通过电泵给液体加速,待克服液体本身的黏滞性后,通过计量流量和标定的体积比较确认,然后再用这个速度给液体进行加速计量,即可实现用一种流量计适应不同黏滞系数的液体体积的计量。
Usually design of a certain flow meter is aimed at certain liquid volume metering, for example, water meter is used for water volume metering, gasoline gauge for gasoline volume, and diesel fuel flow meter for diesel fuel. Apart from the demand of uses for different kinds, technically metering oil volume is inaccurate with water meter because viscosity coefficients vary from different liquids. However, on certain occasions, when it is needed to measure different kinds of liquids conveniently, traditional flue meter is incapable. Accelerate the liquid with electric pump first, when the viscosity of liquid is overcome, meter the flow and compare it with calibrated volume, finally accelerate the liquid with the velocity, thus metering the volume with one flow meter adaptable of different viscosity coefficients is realized.
