Assessing The Effects Of Local Turbulence And Velocity Profiles On Electromagnetic Flow Meter Accuracy, Kade J. Beck
Assessing The Effects Of Local Turbulence And Velocity Profiles On Electromagnetic Flow Meter Accuracy, Kade J. Beck
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this research was to assess the effects of local turbulence and velocity profiles on electromagnetic (magnetic) flow meters. According to the American Water Works Association, “No tool available to water utilities has played a greater part in the conservation of water than the water meter (AWWA 2002).” Consequently, it is imperative to understand what variables may influence magnetic flow meter accuracy.
Even though other researchers have explored the effects of turbulence profile development on orifice plates, the literature is not clear how magnetic flow meters respond to the effect of local turbulence. Accordingly, this study investigated the …
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 …
