Causes of pulsations are defined and classified. Causes for additional dynamic errors of gas flow rate measurement are classified. Mathematical model of pressure gage chamber and connecting tube is developed. Relation between average values of gas flow parameters and the measured gas flow rate is defined. Influence of sampling frequency of differential pressure gage on the measured gas volume is determined. Requirements for measuring equipment at pulsating flow rate measurement are defined. Recommendations in order to eliminate additional errors of natural gas flow rate and volume measurement are developed.
