【Abstract】 The standard volume flow and mass flow of natural gas are related to measuring condition of natural gas, so the compensation is necessary based on the temperature and pressure in measuring condition. The software design for establishing three|dimensional table for modified parameters, inserting data method and checking table program is introduced, and it is used effectively in natural gas flow totalizer.更多还原
