1. A process for measuring methane emissions by an internal combustion engine, the process comprising:

  • positioning a methane sensor at an upper location within a housing, a portion of the gas in an exhaust line of the internal combustion engine entering said by said methane sensor, said housing being connected to the exhaust line of the internal combustion engine;

    forming a baffle within said housing in a location such that the portion of the gas encounters said baffle prior to measurement by said methane sensor such that only gas flows through said housing to said methane sensor;

    connecting the methane sensor to the exhaust line of the internal combustion engine such that the portion of a gas in said exhaust line can enter said housing;

    operating the internal combustion engine so as to produce the exhaust;

    measuring a methane content of the gas with said methane sensor from the portion of the gas from the exhaust line;

    producing an output from said measurement sensor corresponding to the methane concentration;

    separating water from the portion of the gas by said baffle prior to the measurement by said methane sensor; and

    discharging the water outwardly from an interior of said housing.
