- Abstract:
- Due to greater awareness of the rationalization of water resources, Águas do Norte SA has a need to implement new methodologies to control water losses in order to improve the efficiency of their systems.
The Instrumentation&Automation team has developed some procedures, whose objective is to characterize the performance of the various flow meters, trying to reduce one of the components that define the apparent losses in water balance: measurement errors.
The present study has as scope the development of a work tool able to anticipate problems of measurement and equipment operation, in a park of flowmeters that totals about 950 flowmeters, some with about 20 years old and in different installation conditions than the initials. Safeguarding a minimum measurement chain uncertainties, several methods for information acquisition and identification of the flowmeters operating point and associated error were tested. For the calculation of the water balance, the improvement in the flow measurement will allow to quantify and possibly reduce a part of the apparent losses related to the measurement, which can be done in several ways: by replacing flowmeters with other more appropriate ones (reduction of diameter or measurement technology) or the change in operating way of some infrastructures.
The conclusions reached, highlighting the initial stage of the project, suggest that a part of the existing flow meters operate in operating ranges that are not the most adequate, taking into account the metrological characteristics of the meters, causing reading errors that contribute to the increase of apparent losses. - Download:
