Information × Registration Number 0210U003253, 0109U001169 , R & D reports Title Definition and elimination of additional errors of natural gas flow rate measurement at pipeline sections with varying flow parameters popup.stage_title Head Fedoryshyn Roman Myronovych, Registration Date 27-01-2010 Organization Lviv Polytechnic National University popup.description2 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.
