PROBLEM TO BE SOLVED: To provide a supply control system where the amount of integrated values for not less than a storage value stored in a storage medium is prevented from being used even if a time interval for reading the integrated value from a measuring device is prolonged. SOLUTION: A controller 2 previously reduces a prescribed value from the storage value of a storage medium 3, reads a value and stores it as a storage value by a reading a means 8 at the time of starting use. It reads the integrated value of a measuring device 1 at previously decided intervals, reads a value equivalent to a use amount as a use value and reduces it from the storage value. When the reading storage value becomes not more than the prescribed value, a lacking amount is reduced from the medium storage value by the reading means 8 and it is compensated. The storage value which is read is a value equivalent to a maximum supply amount or a value equivalent to a real maximum supply amount when the supply amount of the supply body is monitored for a previously decided period or an amount obtained by multiplying it by a coefficient at an interval for reading the integrated value from the measuring device 1. |
