New method for finding inaccurate gas flow meters using billing data: finding faulty meters using billing data

Abstract [en]

A method that uses billing readings to find inaccurate meters is presented. This method uses these readings to form an individual load index (LI), which is primarily affected by the climate rather than the customer's individual behaviour. Meters used in installations where the gas is used in industrial processes are therefore excluded since the consumption is not affected by the climate. The individual LI is compared with an average LI, and meters that differ from the average LI are examined. The method was tested on the gas distribution network in the city of Lund, which consists of approximately 1500 meters. Based on the results obtained so far, the LI method will be a useful aid in tracking down faulty meters. However, laboratory tests of a large number of meters selected by the LI method are still needed. Extrapolation of the results indicates that at least 1% of the installed meters have substantial errors
