AWWA ACE61844

This paper presents the results of hundreds of accuracy tests of singlemanufacturer 5/8-inch by 3/4-inch domestic residential water meters, all having the same age offield service but varying amounts of cumulative water flow through the meter. The relationshipbetween accuracy and cumulative flow is presented and discussed for AWWA low,medium, and high flow accuracy test regimes. The economics of water meter replacement isdiscussed relative to the accuracy-flow relationships for the three flow test ranges, and theprocess for determining the economic optimum cumulative volume through the meter isdescribed. For the Arizona utility from which the meters tested were derived, the recommendedreplacement timeframe is presented utilizing the specific average annual residential wateruse and water rate structure in effect. The optimum replacement volume for different utilitieswill vary based on water meter environment, water use, economics of meter replacement, andwater rates. Includes tables, figures.
