Ensaio com hidrômetros: verificação da passagem de ar pela tubulação

Abstract

The hydrometer is the device that allows to quantify the volume of water per unit of time that is destined to the residence and/or company, and that allows to monitor the consumption of water where it is necessary to carry out a charge for the use or even for the monitoring of its use, in cases where there is no charge. The objective of this work is to identify if the passage of air through the hydrometer causes changes in the flow monitoring, as well as the efficiency of check valves. The adopted methodology included the collection of data from laboratory experiments, inserting air next to the water flow and recording the values ​​shown in the hydrometers and compared with the graduated container, being later made a statistical analysis by means of a computer program. After the tests, it was proven that the air present in the network causes significant changes in the marking of the water meters, and the use of the check valve did not show improvement in the markings of the water meters in general and showing a worsening in the marking in one of the water meters.
