Abstract
A method of mixing at N gases is provided. This method includes providing N gas flow meters, including N gas flows, wherein N is 3 or more. Measuring each of the N gas flows, at first predetermined intervals of time, and totaling each of the measured N flows over a second predetermined interval of time. Adding the N measured gas flows, thereby determining the total gas flow at the second predetermined interval of time. Dividing the total gas flow for each of the N gas flows by the total gas flow, thereby determining a cumulative calculated theoretical percentage for each of the N gas flows over the second predetermined interval of time. And sounding an alarm, and/or terminating the N gas flows, if the cumulative calculated theoretical percentage for any of the N gas flows exceeds a predetermined range value.
