FLUIDIC GAS METER

摘要

PROBLEM TO BE SOLVED: To provide a fluidic gas meter having a gas pressure fluctuation removing means which can be assembled easily using inexpensive parts. SOLUTION: A gas pressure fluctuation removing means 37 and a fluidic flowmeter are provided in this order in the gas channel of a gas meter body along the passing direction of gas. A valve 42 which can be seated on a valve seat 82 is fixed to one end part of a connecting rod 70 having the other end connected with a diaphragm 43. The diaphragm 43 brings the valve 42 closer to the valve seat 82 as the difference between the pressure in a valve chamber 67 and the pressure on the gas discharge opening side decreases. When the connecting rod 70 is held substantially horizontally by means of the valve 42 side end part 71 of a bearing 72 and the diaphragm 43, sliding resistance between the bearing 72 and the connecting rod 70 is decreased even if they are made of the same kind of synthetic resin and movement of the valve 42 is made smooth.
