通过分析从装有便携式数据记录器的住宅用户水表中获得的流量轨迹，可以收集有关用水模式的精确信息。水流轨迹足够精确，可以识别与所有主要用水类别相关的特征。在这项研究中，超过10000个用水事件被记录、分类并输入数据库。该技术准确可靠，可用于收集特定时间和分类的用水数据。直接测量而不是从聚合数据推断测量值是分析用水模式和直接评估保护措施如何影响水需求的一种快速且经济有效的方法。 包括8个参考文献、表格、图表。

Precise information about water use patterns can be gathered by analyzing flow traces obtained from residential customer water meters that are fitted with portable data loggers. Flow traces are precise enough that signatures associated with all major water use categories can be identified. For this study, more than 10,000 water use events were recorded, classified, and entered into a database. The technique is both accurate and reliable and can be used to collect time-specific and disaggregated water use data. Measuring directly instead of inferring measurements from aggregated data is a quick and cost effective way to analyze water use patterns and directly assess how conservation measures influence water demand. Includes 8 references, tables, figures.
