Abstract

A találmány tárgya gázmérő (10), amely bűrkőlatőt (12) tartalmaz, abűrkőlatőn (12) gázbemenet (14) és gázkimenet (16) van kiképezve, abűrkőlat (12) belsejében mérőegység (18) van elhelyezve és legalábbegy őlyan nyílásssal (20) van ellátva, amelyen keresztül a gázáram amérőegységbe (18) van elvezetve, és legalább egy nyílás teszilehetővé, hőgy a gáz a mérőegységből (18) a gázkimeneten (16)eltávőzzőn. A találmány lényege abban van, hőgy a mérőegységnek (18)van egy, a gázbemenettel (14) szemben elhelyezkedő fala, (18a),amelyen a bejövő gázáram felütközik, és a nyílás (20) kizárólag amérőegység (18) az előzővel szemben lévő falán (18b) van kiképezve. ŕThe subject of the invention is a gas meter (10), which contains a gas meter (12), gas inlet (14) and gas outlet (16) are formed on the gas meter (12), a measuring unit (18) is placed inside the gas meter (12) and has at least one such opening (20) provided, through which the gas flow is led to the measuring unit (18) and at least one opening can be made, so that the gas from the measuring unit (18) can be removed via the gas outlet (16). The essence of the invention is that the measuring unit (18) has a wall (18a) located opposite the gas inlet (14), on which the incoming gas flow hits, and the opening (20) is only on the wall of the measuring unit (18) opposite the previous one (18b) is trained. ŕ
