PROBLEM TO BE SOLVED: To verify that a set amount is correct when a combination of a plurality of containers are filled with a liquid. SOLUTION: In the fluid feeder, display devices 34 and 36 provided in a weighing machine read card information on a prepaid card inserted in a card reader, the set amount is displayed on a set amount display part 48 based on the card information, and the number-of-cans display part 50 displays the capacity of the container and the number of boxes (the number of plastic containers). Thus, a customer can check the set amount (amount to be fed), the capacity of the plastic container 44, and the number of boxes before starting to feed the liquid. If the amount thus set is wrong, the container capacity and the number of boxes displayed on the display part 50 are different from the capacity of the container the customer carries and the number of boxes so that the wrong set amount can be easily identified.
