PURPOSE: To obtain a fluidic gas meter which can be suspended, as it is, from a part from which an existing N-type gas meter is removed while stabilizing the operation of a built-in governor.
CONSTITUTION: In addition to a lower gas flow-in port 5 and a lower gas flow- out port 6, an upper gas flow-in port 3 and an upper gas flow-out port 4 are provided at the upper part of a fluidic gas meter 1 while being matched with the interval of the base metal of an existing N-type gas meter. Connection pipe 16 of the existing N-type gas meter is coupled directly with the upper gas flow-in and flow-out ports 3, 4 thus suspending the fluidic gas meter 1 and then the pressure introduction passage 18 for a governor 17 is coupled with an upper gas flow-out line 8 passing close by the pressure introduction passage 18.
