METHOD FOR METROLOGICAL DIAGNOSTICS OF MEASURING PIPELINES WITH COMMON INPUT AND OUTPUT COLLECTORS THAT ARE INCLUDED TO SET OF GAS FLOW RATE METERS

摘要

Method for metrological diagnostics of measuring pipelines with common inlet and outlet collectors that are included to set of gas flow rate meters includes implementation of measurement of gas flow rate on measuring pipelines, determination for measuring pipelines error of measurement of gas flow rate, comparison of value of error obtained to given critical values and formation of signal on metrological failure of measuring pipeline in case if value of error obtained exceeds given critical value. At each of measuring pipelines one performs current measurement of gas flow rate by second method. Results of current measurements obtained by different methods are compares to each other. Signal on metrological failure of measuring pipeline is formed in case if results obtained by different methods of measurements for gas flow rate differ one from another by value that exceeds given critical value.
