Monitoramento remoto de sobremedição de hidrômetros domiciliares em bancada simulando rede de abastecimento de água

Abstract

This work addresses one of the problems related to the intermittent supply system, which commonly occurs in regions of Brazil. This type of system entails some challenges for both the operator and the final consumer. One of them, the air that enters the piping in the system and flows to the micro measurement of the houses, which can generate distrust of the consumer in relation to the operation of the hydrometer. In this sense, the objective of this work was to develop a Datalogger with pressure measurements from a conventional hydrometer and the pulses generated by an ultrasonic hydrometer in an experimental supply network of the hydraulic module of the Hydraulics Laboratory of the Department of Sanitary and Environmental Engineering at UFMT , simulating an intermittent supply network. The methodology consisted of installing a prototype with an Arduino Mega microcontroller, which collected data and a Datalogger in a conventional hydrometer and an ultrasonic hydrometer. The data cataloged were pressure from the supply network, house pressure, consumption of an ultrasonic water meter, date and time. When the water supply ceased, a camera was used to record the conventional hydrometer turning in the opposite direction to the nominal one. With this it was possible to prove the existence of air due to the type of intermittent supply and its consequences. Make the residential water meter bill water consumption, even if the air makes the water meter rotate.
