METHOD FOR EXPRESS-EVALUATION OF METROLOGICAL CHARACTERISTICS OF A UNIT FOR GAS REGISTRATION IN SET OF GAS METER AND TEMPERATURE CORRECTOR OF GAS VOLUME AT PLACE OF OPERATION

摘要

The invention relates to measuring engineering. A method for express evaluation of metrological characteristics of a unit for gas registration in set of a gas meter and temperature corrector of gas volume at site of operation includes sequential connection of a control measuring mobile set to the unit for gas registration. According to the invention, one disconnects the unit for gas registration from the system of gas supply, as working medium one uses air that is passed through the unit for gas registration and control measuring mobile complex. The beginning and the end of measurements are set at instant of the initial and the end pulses from the gas meter to corrector of gas volume. At processing results of measurements, the gas volume, brought to standard conditions, which has passed during time of measurements through the mobile set one determines on basis of value of its pulse and coefficient of transformation. The technical result is in increase of the level of safety at carrying out express evaluation of meteorological characteristics of the unit for gas registration at preservation of reliability of results of express evaluation.
