What is the flow in a flowmeter?
Average flow: in the measurement time, the average value of the flow can also be called the average flow.
Flow: the amount of fluid flowing through a pipe cross section or an open channel cross section (referred to as a cross section) during unit time. When the mass of fluid is expressed in mass, it is called mass flow, and the volume of fluid is called volume flow when it is expressed in volume".
Rated flow: the flow value of a flow meter at specified performance or optimum performance. It is indicated by the maximum or (and) minimum limit.
