PROBLEM TO BE SOLVED: To provide a gas meter made small in size and light in weight by allocating each of parts without useless space. SOLUTION: High gas channels CH1, CH3 in high flow rate measuring sections 11a2, 11b are set so as to be parallel to the direction in which a link mechanism 13 is opened and closed when it is driven. The high flow rate measuring sections 11a2, 11b and the link mechanism 13 are arranged side by side.
