A method for control of gas-measuring station includes periodical determination of gas flow rate by each operating measuring pipeline. At determination of gas flow rate at each measuring pipeline one measures pressure drop -at constricting device and pressure -of gas in pipeline. One compares measured value of pressure drop from the upper -and the lower -working limits of the range of measurement of pressure drop sensor and the measured value of gas pressure from the upper -and the lower -working boundaries of the measurement range of the pressure sensor and, if measured value of one of those parameters is larger than the upper working limit set for it, i.e.or, or, if the measured value of one of those parameters is smaller than the lower working limit set for it -or, operational staff is informed that measuring pipeline has gone out of working mode. |
