Resumo
Aiming to combat the apparent losses, the hydrometer’s park has to be object
of preventive active maintenance, with careful evaluation of hydrometers to be replaced.
One of the main functions of the measurer’s replacement is reduce the sub‐metering,
registering the consumption accurately. However, the measurers should register the
intake influx and reflux, that may influence the recorded volume in a determined period.
Thus, benchtop and field studies were performed in order to verify the performance of
volumetric and velocimetric new measurers, from different manufacturers. At benchtop
study were observed ranging errors from ‐ 15.5% to ‐100% in reflux for velocimetric
measurers, and to volumetric measurers tested, errors at study situations were virtually
similar, don’t influencing the volume recorded by measurer. The field study showed that
velocimetric hydrometer from A's manufacturer registered, in 7 days, 800 L more than the
volumetric meter from F’s manufacturer, indicating that reflux due to water balance in the
network directly influences the volume registered by the velocimetric measurer, affecting
the monthly charging of water's supply users. Aiming to solve reflux cases, backstop valves
were installed in ten water connections that presented water balance problems at
distribution network. In these places, the problems were solved, and was observed a small
decrease in registered volume.
