液体流量的测量一般用定容积法或定质量法。定容积法是使被测液体不断充满一定容积V的容器,由记录器记录充满容器所需的时间T,则被测液体的体积流量为Q=V/T。定质量法是使被测液体不断充入天平的称盘内,由记录器记录充入一定质量M所需的时 Liquid flow measurement generally used constant volume method or qualitative method. Constant volume method is to make the measured fluid constantly filled with a certain volume of container V, the recorder records the time required to fill the container T, then the measured volume flow of liquid Q = V / T. Constant quality method is to make the measured liquid constantly charged balance weighing plate, recorded by the recorder when required to fill a certain mass M
