A method for control of operation of gas-measuring station includes periodical determination of gas flow rate by each operating measuring pipeline. At each determination of gas flow rate at each measuring pipeline one measures the value of main parameter that characterizes gas flow rate, with comparison of measured value of that parameter to the upper working limit of the range of measurement of that parameter equal to, where- the upper limit of the range of measurement of sensor,- the upper relative working boundary of the range of measurement of parameter, and to the lower working boundary of the range of measurement of the parameter that is equal to, where- the lower relative working boundary of the range of measurement of the parameter. If the value measured is larger than the upper working boundary of the range of measurement of the main parameter -, a signal is generated by which operator brings into operation an additional measuring pipeline. If the value measured is smaller compared to the lower working boundary of the range of measurement of the main parameter -, a signal is generated by which operator takes out of operation one measuring pipeline. |
