A gas flow measuring system comprising a gas flow conduit for carrying a gas mixture of known constituents in unknown proportions, a gas analyser (34) coupled to the conduit and generating analogue signals representative of the unknown proportions of the gas mixture, and a mass flow meter (38) coupled to the conduit and generating an analogue signal representative of the mass flow rate of the gas mixture. Further, the system includes a converter (108) for conversion of said analogue signals to digital signals, a digital processor for processing the digital signals from the converter, for producing output data of interest, such as volumetric flow rate of the gas mixture, a display means (60) for graphically and numerically displaying output data from the processor (58) in real time, and a storage means for long term storage of output data from the processor in a format which can be processed at a later time. |
