The gas flow devices are fluidly connected at a connection that mixes the gases to provide a diluted exhaust gas having an incorrect dilution ratio. A water measurement device such as an analyzer measures the water content of the exhaust gas, preferably subsequent to dilution. A water content dilution signal corresponding to the water content in the exhaust gas is sent from the water measurement device to a control device.Type: ApplicationFiled: August 31, 2004Publication date: February 10, 2005Inventors: William Silvis, Norbert Kreft, Gerald Marek, Wolfgang Schindler
