Resumen
This paper describes the methodology used to evaluate water meters performance in a Spanish water supply system. During the study 238 meters of two brands were tested in the laboratory at four different flow rates. A detailed analysis of the starting flows was also carried out. For determining the typical water consumption pattern in the city 58 households of different characteristics were monitored. This two parameters were used to calculate meters weighted accuracy and the optimal renewal frequency and average annual costs for both type of meters. Finally a sensitivity analysis established the influence of water and water meter price on the optimal replacement frequency.
