<p>The disclosure relates to a measuring apparatus and method for determining a measured value in a gas flow accounting for cross-sensitivities of the measuring appliance from at least one additional constituent in the gas flow interfering with the measured value. The measuring apparatus has a device for dividing original gas flow to be measured into a first and second measured gas flows, a device for changing the content of measured gas in the second measured flow by changing an influencing variable that influences the content of the measured gas, and a sensor element having a sensor for determining the value. The apparatus includes an evaluating unit for evaluating the measured values, wherein first and second measured flows are alternately fed to the sensor element to determine two intermediate measured values in two measured flows, respectively. The evaluating unit calculates the final value based on the two intermediate measurement results.</p> |
