The calculator program in this study predicts the differential pressure created by an orifice meter at any selected flow rate of a gas. In most cases, deviation of the predicted flow rate from the actual will be less than + 3%. Before the pressure differential can be predicted, certain parameters pertaining to the orifice meter and the gas stream must be known, as listed. An equation is used to predict the differential pressure across the orifice for a specific flow rate of gas. This equation, when used in conjunction with the graphs presented, predicts the maximum pressure drop that can be measured across an orifice. For this reason, vena-contracta taps should be used when applying the method presented.
