摘要： The present invention concerns a gas meter (10) comprising: a box-shaped body (11), an inlet mouth (15) and an outlet mouth (16) suited to allow the passage of a gas flow and defined on said box-shaped body (11), wherein inside the box-shaped body (11) there is a metering device (19) designed to measure one or more parameters for the determination of the gas flow rate, said metering device (19) being provided with an inlet opening (19a) and an outlet opening (19b). Said gas meter (10) comprises: an inlet duct (25) extending from the inlet mouth (15) towards an opposite side of the box- shaped body (11), an outlet duct (40) extending between the outlet mouth (16) and an opposite side of the box-shaped body (11), the metering device (19) being positioned in an intermediate area between the inlet duct (25) and the outlet duct (40).

摘要： The present invention concerns a gas meter structure (10) comprising a box-shaped body (11), an inlet mouth (15) and an outlet mouth (16) suited to allow the passage of a gas flow and defined on the box-shaped body (11), wherein inside the box-shaped body (11) there are a metering device (19) suited to measure one or more parameters for the determination of the gas flow rate, filtering means (17) suited to filter the gas flow. The filtering means comprise a dust deposit chamber (26) for the dust present in the gas flowing in, said dust deposit chamber (26) comprising an inlet opening (26a) communicating with the inlet mouth (15) of the box-shaped body (11), a dust collection bottom (26b) and a filtering outlet wall (28) provided with through openings (28a); the dust deposit chamber (26) is configured in such a way that the gas flows into it through the inlet opening (26a) and flows out of it through the through openings (28a) of the filtering outlet wall (28).
