Estimación de la precisión en la micromedición del sistema de abastecimiento de agua de Pereira Estimation of precision in the micro- measurement of the water supply system in Pereira

The management of water resources in urban centers involves continuous monitoring and control of resource use in order to improve service delivery and achieve efficiency in the consumption by the users. In this sense, the meter measurement becomes the main control tool for the efficient water use, whose optimization is related to the technical capacity of the company, the technology used and its accuracy. This research evaluated the performance of the measurement devices in the urban water supply system of Pereira city, considering the company commercial information system, the data allow to inference the attrition of different measurement devices, considering its features techniques and the impact on water consumption by users. It was mainly found more attrition in class B meters, compared to class C, and the negative impact on consumption is higher when the user was confronted to the latter class.
