Annotations languages:

Sources of uncertainties at calculation of gas flow rate and gas quantity are considered. Necessity of carrying out of detailed instrumental researches for additional component by uncertainty of measurement of gas-flow rate. The results of suggested researches will allow to raise the reliability of gas-flow rate calculation at gas-measuring stations (GMS) and will promote reduction of gas quantity unbalances in the gas-transport system of Ukraine.
Keywords: uncertainty, a gas stream, the account of the expense and quantity of gas
