The condensate separator includes a housing with condensate discharge opening, an inlet opening arranged in the housing, a cooled inlet line which introduces a fluid into the housing, and a gas outlet port with a gas entrance and a gas exit. The cooled inlet line opens into the inlet opening. The gas outlet port opens into a gas outlet line. A cross-sectional area of the gas entrance of the gas outlet port is larger than a cross-sectional area of the gas exit of the gas outlet port. ## Claims ### Claim 1 A condensate separator for an exhaust gas measuring system, the condensate separator comprising: a housing comprising a condensate discharge opening and an upper base surface; an inlet opening arranged in the housing; a cooled inlet line configured to introduce a fluid into the housing, the cooled inlet line being arranged to open into the inlet opening; and a gas outlet port comprising a gas entrance and a gas exit, the gas outlet port being arranged to open into a gas outlet line and to extend outwards from the upper base surface of the housing, wherein, a cross sectional area of the gas entrance of the gas outlet port is larger than a cross sectional area of the gas exit of the gas outlet port. ### Claim 2 (depends on 1) The condensate separator as recited in claim 1, wherein, the housing further comprises a side wall, the inlet opening is arranged on the side wall of the housing, and the cooled inlet line is further configured to tangentially open into the housing. ### Claim 3 (depends on 1) The condensate separator as recited in claim 1, wherein the gas outlet port further comprises a conical section which is arranged between the gas entrance and the gas exit. ### Claim 4 (depends on 1) The condensate separator as recited in claim 1, wherein the cross sectional area of the gas entrance is twice as large as the cross sectional area of the gas exit. ### Claim 5 (depends on 1) The condensate separator as recited in claim 1, further comprising: a cooler, wherein, the cooled inlet line is arranged to helically pass through the cooler. ### Claim 6 (depends on 1) The condensate separator as recited in claim 1, wherein a diameter of the cooled inlet line corresponds at least to a diameter of a condensing droplet. ### Claim 7 (depends on 1) The condensate separator as recited in claim 1, wherein the housing further comprises, a cylindrical housing section which has the inlet opening arranged therein, and a conical housing section which is arranged adjacent to the cylindrical housing section and which has the condensate discharge opening arranged therein. ### Claim 8 (depends on 1) The condensate separator as recited in claim 1, wherein a diameter of the gas entrance of the outlet port corresponds to a diameter of the upper base surface of the housing.
