As water scarcity increases, improved water management through better water measurement is of critical global significance. Today, the most common way to measure water in drinking water and wastewater systems is to use an electromagnetic (magnetic) flowmeter. A magnetic flowmeter has many components, and their accuracy can be compromised if not installed or calibrated correctly. The purpose of the present study was threefold. Each of the three components has been named to help the reader understand the context of the study without getting lost in the details.

The Idealist. Using mathematical programs, the spacing of two types of magnetic flowmeter sensors was optimized and the performance of these sensors was numerically compared to the standard sensors in use today.

The Egalitarian. Not all researchers who are interested in magnetic flowmeter analysis are trained to understand how they work. Thus, some researchers are limited in their abilities to identify improvements to water measurement practices. Consequently, an alternative magnetic flowmeter analysis method was compared to the traditional magnetic flowmeter analysis method and found good agreement, thereby enabling a new group of researchers to analyze magnetic flowmeters.

The Capitalist. Computer models can be used to predict the flow of water through pipes. Some models match laboratory observations better than others but are more ex-pensive to use. This segment of research explored how sensitive magnetic flowmeters are to less expensive and more expensive models and found that they appear to exhibit some sensitivity to the choice of model.
