Previous studies have identified water meter inaccuracy at low flow rates as a significant source of non-revenue flow for water systems; however a lack of available data makes it difficult to include low flow accuracy degradation in meter replacement plans. This thesis examines results from an extensive accuracy test program carried out at the Utah Water Research Laboratory on small water meters over a wide range of flow rates and at various levels of throughput. The study compares expected apparent losses of different types of water meters based on a flow profile and expected daily use for the State of California. By including an average composite charging rate, use of the method developed in this study can determine the meter replacement payback period for different meter types. The analysis contained in this document is intended as a guide to assist utility managers when developing meter replacement plans.
