Vlasyuk Y. Improvement of means and normative documents for the metrology providing of knots of account of natural gas

Dissertation is devoted the decision of actual task of increase of exactness and reliability of work of turbine, ultrasonic and rotor meters of gas. It is rotined that these meters in transitional behaviors have considerable dynamic errors which must be taken into account at the account of gas by these meters. Possibility of determination of gas density is grounded by successively united Venturi and rotor meter.Influence of pressure, temperature and type of measureable gas on metrology descriptions of turbine, rotor and ultrasonic meters is experimentally appraised. The results of such estimation can be utillized in the operating systems of account of natural gas. The new type of metrology description is offered "midlle weigh" additional error. Considerable attention is spared also development of two normative documents for organization of the proper functioning of industrial meters of gas and verification of the technical state of knots of his account.
