Claims

[Scope of utility model registration request]

a timer means for emitting a signal at fixed time intervals; a counter means for counting the number of flow pulses having a repetition frequency corresponding to the flow rate of the fluid; and a counter means for counting the number of incoming flow pulses within the fixed time period; A flow rate correction device comprising a calculation means for correcting the incoming number and calculating a period of correction pulses to be output evenly within the certain period of time, and a pulse generation means for generating and outputting a correction pulse for each period.
