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