在文献中还很少报导有关测量液体和气体小流量的工作计量器具。下面介绍的装置可补充这方面的资料,并可用于具有封闭式流量管道的试验系统和试验机械中,不管工作介质的压力大小和温度高低都能测量液体和气体的小流量。这种装置的特点是:它能保证进行实际上从零差压流量开始的测量,还能保证进行体积
Little is still reported in the literature about working measuring instruments for measuring small volumes of liquids and gases. The devices described below complement this information and can be used in test systems and test machines with enclosed flow lines to measure low volumes of liquids and gases regardless of the pressure and temperature of the working medium. The device is characterized by: it can guarantee the actual measurement from zero differential pressure flow, but also to ensure the volume
