Desenvolvimento de sistema automatizado de baixo custo para medição inteligente de vazão em redes de abastecimento.

Abstract

The Brazilian water supply systems (WSS) still have low levels of macro measurement and species of significant species. The increase in demands for water resources associated with these high levels of water generates a worrying scenario regarding the supply of water, with a more efficient management of water resources. Automation is a technology that can assist intelligent water monitoring and WSS by minimizing recurring problems in distribution networks. It aimed to develop an intelligent water survey system from low-cost automated devices to help manage water in distribution networks. The supply network of the Federal University of Campina Grande (UFCG) Campina Grande-PB was used as an experimental area. The methodological steps were: the development of the operation and the validation of the UFCG to supervise the data under uncontrolled conditions. The device was developed to be satisfactory for use in pipes with a performance ratio of =0.5, obtaining errors of less than 2.5% for flows greater than 3 m3/hour, as performed from two reference gauges, the rotameter and the Gull Press-1000 manometer. The installation of the intelligent problem in the network for the presentation of some difficulties, mainly due to the interruption without interruption, which compromised as a network, since the configuration through the configuration is provided for uninterrupted supply. When the flow in the pipeline is established, sufficient sensitivity is presented to identify the pressure and circulation in the network in a defined experimental section. The collection data, by the temperature measurement system in the network, was sent for pressure monitoring and real monitoring flow and the verification of consumption anomalies of the characteristic was installed. The total cost of the highly intelligent developed and installed was R$453.80, lower than the natural resources of macro supply, with a cost up to 33 times higher than the one developed and without the digital remote functionality. The designed solution was used for the operation of intelligent solution and can be used in a list of models with solution designed for the operation of systems and can be used for the management of designed solutions valid for the operation of systems and can be used in the management of solutions. The application on the network of optimized behavior to obtain the consumption characteristics in time optimizations during the observation period for resources and observation period for resources 1 and 2 tuning, which present the network time. This operating mode influenced an intelligence system shown to be an instrument of intelligence studied in pipes, being a tool that is not specific for water, operation and management of water losses in networks with characteristics.
