PROBLEM TO BE SOLVED: To easily and rapidly take appropriate measures according to an apparatus in use or service condition by determining the apparatus in use. SOLUTION: This gas apparatus control system includes: a unit 10 on a user side, which is provided with an ultrasonic flowmeter 11 connected to a gas filler tube 20 and measuring the instantaneous flow rate of gas, a flow rate calculating section 12 calculating a difference value of the flow rate for determining the apparatus from the instantaneous flow rate, an apparatus determining section 13 determining the apparatus in use by the flow rate change characteristics of the flow rate of the gas such as a variation and time of a change in the flow rate based on the difference value of the flow rate, and a communication section 41 transmitting information on service condition including information on the flow rate and information on the apparatus in use; and a control center unit 40 receiving information on the service condition from the unit 10 on the user side and selectively prescribing measures according to the flow rate and the result of determination of the apparatus.
