摘要： PROBLEM TO BE SOLVED: To provide a gas meter capable of preventing dust from entering into a flow rate measuring part without causing increase of pressure loss due to dust accumulated therein for a long period of time.SOLUTION: In a casing 2 of a gas meter 1, an inlet 11 of a flow rate measuring part 10 is opened within the casing 2, and an outlet 12 of the flow rate measuring part 10 is connected to a flow-out part 4. A filter 14 which has an area larger than the inlet 11 is disposed at a position to partition the flow-in portion 3 from the inlet 11. With this, the flow rate is reduced in a wide space of the casing 2 of the gas meter 1 to thereby allow dust to fall down. Further, the filter 14 which has an area wider than the inlet 11 catches the dust at a lower flow rate before the dust enters the flow rate measuring part 10; thereby the dust catch efficiency is increased while preventing the pressure loss from increasing due to the dust accumulated for a long period of time. With the combination of the above effects, dust is prevented from entering the flow rate measuring part 10.
