5.4 Computing device

The gas analytical system may be equipped with a computing device (such as a data processing unit or a personal computer), which calculates emissions (e.g. the average emission during the specified time, etc.) and transmits their values to the printing device with an estimated uncertainty. The relevant authority shall certify the computational algorithm of the measurement results and their estimated uncertainty.

Since information about the flow rate, temperature, gas pressure and diameter of a pipe (gas duct) is necessary to calculate the stationary source emissions, such information shall be provided with the required accuracy and automatically introduced into the computing device.
