   Should water meter accuracy be a priority for utility managers?

   • Water meter accuracy is a high priority for utility managers because, as mechanical devices, water meters are subject to wear. Wear contributes to meter accuracy degradation, meaning that the water meters become less efficient for measuring flow and will generally underregister the actual throughput.
