摘要
In order to accurately calculate an estimated flow rate by a dynamic constant volume method, a flow rate calculation system including a tank into which fluid flows, an inflow line through which the fluid flows into the tank, and a pressure sensor that detects the pressure inside the tank is adapted to include: a pressure change data storage part that stores pressure change data indicating a temporal change in the pressure detected by the pressure sensor during an inflow period; a flow rate calculation part that calculates the estimated flow rate during the inflow period based on a pressure change rate; and a flow rate correction part that, on the basis of first pressure detected by the pressure sensor after a predetermined time has elapsed after the inflow period and second pressure included in the pressure change data and higher than the first pressure, corrects the estimated flow rate.
