Abstract

Household water meters are tested/calibrated at steady flow conditions however, during their actual usage, flow conditions are not always steady and not so much known about the flow dynamics. The present paper reports about instantaneous flow rate measurements conducted at households to find out what kind of flow rate profiles exist through household meters. From these measurements, 3200 single water consumption events were extracted. Then each single event was analysed to obtain various information such as rise time, fall time, amplitude, event duration and consumed water volume. These results showed that the distributions of rise and fall times with respect to number of events are mostly around 100 to 300 ms. And more than 5% of the flow time, the meter is under dynamic flow conditions.
