1. A multifunctional dust trap for reducing an acoustic noise and dust filtering, the multifunctional dust trap comprising:
an inlet connected to a gas inlet of a gas meter;
a chamber, connected to the inlet, to receive a flow of a gas and to reduce an acoustic noise by a reflection at one or more inner surfaces of the chamber, wherein the chamber comprises:
a first wall to deflect the flow of the gas in a first direction, wherein the first wall directs the flow of the gas into a cross sectional area of the chamber, which reduces a velocity of the deflected gas such that a centrifugal force guides a plurality of dust particles carried by the gas towards a base of the chamber; and
a second wall to deflect the flow of the gas in a second direction, wherein the flow of the gas is deflected from the first direction to the second direction; and
an outlet, attached to the chamber, to enable an exit of a clean flow of the gas from the multifunctional dust trap such that the clean flow of the gas is directed away from one or more flow inlets of a flow tube installed within the gas meter resulting in a smooth flow of the gas in the flow tube, and
a plurality of ribs extending vertically in an upward direction from the base and transverse a direction of the flow of the gas, and wherein each of the plurality of ribs and/or one or more inner surfaces of the multifunctional dust trap comprises a coating of a sticky material.
