科氏质量流量计不断改善性能 提高竞争力
发布时间:2018-12-13   点击次数:361次

  流体在旋转的管内流动时会对管壁产生一个力,它是科里奥利在1832年研究轮机时发现的,简称科氏力。科氏质量流量计即是根据此原理研发出的一款质量流量计

  科氏质量流量计适用于各种液体,如腐蚀性、脏污介质、悬浮液、两相液体(液体中含气体量<10%体积)等。可直接测量质量流量,与被测介质温度、压力、密度、黏度变化无关。

  从原理上讲Fc=2ωVM,在被测流体一定时,只有加大ω或V,才能提高Fc。实际中ω的增加,在仪表上就需要提高振动频率和振动的振幅。振动频率的提高,严重地影响测量管的寿命,而振幅的提高就需提供较大的动力。V的增加就是增加流速,这样即增加了测量管上的静压,也增大流量计对整个系统的压力损失。这些对流量计本身和整个系统都是不利的。
