Water consumptions of end-users show temporal changes depending on the life style of consumers. The frequency distribution of water consumption extracted in the context of this study is given in Figure2 and shows that a large amount of water (76.2% of total water consumption) is consumed at flow rates between 120 and 1,200 L/h. However, selection of water meters is generally based on the initial measurement performance and cost of the water meters. Technical requirements of water meters define an error curve using minimum flow rate (Q1), transitional flow rate (Q2), permanent flow rate (Q3) and overload flow rate (Q4) (Fontanazza et al. 2011; Fontanazza et al. For this purpose, water consumptions of typical residential end-users were monitored to determine flow rates and water consumption patterns were extracted from obtained data. Offering you an extensive selection of the best brands for substantial savings on your energy consumption costs. Tested volumetric-type water meters have the lowest starting flow rate and the highest accuracy whereas single-jet water meters have the lowest accuracy and the highest starting flow rate. Thus, no friction losses or relatively low friction losses occur in water meters with wet chambers, as power transmission from the water chamber to the counter takes place directly. Minimum flow rate is the lowest flow rate that the water meter starts to measure within maximum permissible errors (MPEs), whereas overload flow rate is the highest flow rate that the water meter operates for a short time period within MPEs. 
Real losses refer to the water that is physically lost while apparent losses are the sum of losses which are used but not paid for (Al-Washali et al.
