とを特徴とする流量測定装置。In a flow rate measuring device equipped with a level meter that measures the water depth of a waterway and a current meter that measures the point flow velocity or linear flow velocity of the waterway, the flow rate coefficient Kq given according to a predetermined waterway:
A function generator with preset characteristics of Kp-A or Kq = Kl・A (Kp is a point correction coefficient, K1 is a line correction coefficient, and A is a flowing water cross-sectional area) is installed, and it corresponds to the water depth input detected by the level meter mentioned above. The flow rate measuring device is characterized in that the flow rate of the waterway is measured from the current flow rate count output by the function generator and the flow velocity detected by the current meter.
