The Accuracy of District Meters
District meters are essential to leakage management and increasingly used in pressure management and smart networks. Understanding their performance, therefore, is important. Currently the majority of district meters are turbine types but the proportion of electromagnetic meters is increasing. Data from many sources have been analysed to identify the influence of factors, including sizing, installation and age, on installed accuracy. Electronic verification maintains confidence in electromagnetic meters and hydrant meters used to check mechanical meters when problems are suspected. The uncertainties of individual meters should be evaluated when compiling bottom up leakage estimates. However, this process requires good asset records.
