Flowmeter It can be divided into instantaneous flow rate (Flow Rate) and total flow rate (Total Flow). Instantaneous flow rate is the amount of the effective section of the closed pipeline or open channel in a unit time. The cumulative flow rate is the cumulative measurement of the effective section of the closed pipeline or open channel in a certain time interval (one day, one week, one month, one year).
