Accuracy Of Residential Water Meters In Response To Short, Intermittent Flows, John R. Chadwick
Accuracy Of Residential Water Meters In Response To Short, Intermittent Flows, John R. Chadwick
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In this study, water meter accuracy in response to short, intermittent flows was tested. Burst flows have short durations (a few seconds or less), and occur at a variety of flow rates. For some types of meters, it is difficult to accurately measure short, intermittent flow rates. Depending on the meter type, an intermittent flow can result in either under-registering or over-registering of the actual throughput.
During the testing for this research, water was passed through meters for various time combinations, test setups, and flows. It should be understood that realistically, a household setting will not see burst flows occurring …
The Effects Of Surge Flows On Residential Water Meters, Ryan P. Weller
The Effects Of Surge Flows On Residential Water Meters, Ryan P. Weller
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
All residential water meters have published flow rates for which they will operate as designed. These specifications include a maximum operating flow rate, which is recommended not to exceed. However, there are situations which may cause a meter to flow above the maximum flow rate. This thesis explores what effect these surge flows have on residential water meters.
Twenty-one 5/8”x3/4” meters were tested in this study: three oscillating pistons, six nutating disks, nine ultrasonic, and three electromagnetic. Testing was done at the Utah Water Research Laboratory using a gravimetric test bench specifically designed for residential water meter testing.
The results …
