Abstract
In order to ensure the same conditions as for flow calibration, in case of a single-person household provided with a class B multi-jet propeller water meter with nominal diameter of 20 mm, a thermally insulated storage tank was built. During the exploitation, the storage tank will be fed by calibrated constant discharges in stages. For the purposes of measured consumption cumulative curve, the needed tank volume, flow rate and minimum duration of the filling stage were defined in the function of water meter reading accuracy (1 litre, 0,1 litre and 0,025 litre). The measurements proved that the thermally insulated tanks were able to keep water temperature within the range identical to that measured in the water supply in a single-person household.
