Dec 1, 2012 · Water utility managers generally agree that water meters, especially mechanical water meters, experience a degradation of accuracy over time. This degradation is a function of several factors, such as wear, water quality, water velocities, throughput volumes, and installation and handling.

Jun 15, 2024 · The reliability of Company A's meters decreases significantly from the time they are put into service and approaches zero after 110 months of use. The reliability of instruments from Company B and C is close to zero after 150 and 130 months of service, respectively.
Jan 4, 2021 · This paper proposes a methodology that allows determining the operation of the domestic water meter by analyzing the metrological quality and degradation of accuracy, specifically by the statistical calculation of the weighted measurement error, the annual degradation and the volume of apparent losses of the domiciliary meters installed in ...

Feb 25, 2021 · Low median working pressure caused an increase in meter under-registration. Meter age was the most sensitive parameter. The ability of the model to accurately predict the meter registration degenerated with an increasing annual billed volume. Model 2 meters were the most suitable meters in the KWDS.
