Flow meter accuracy is an important part of any utility's ability to manage its system. Even though a meter may test as being accurate under one set of conditions, it may have significant error under another set. This paper summarizes seven different techniques available to verify the installed...

A comparison of these measurement terms is shown graphically in Figure 4.2.1 Fig. 4.2.1 Range of error Figure 4.2.1 demonstrates why meter manufacturers state their accuracy as a combination of both a percentage of FSD and actual reading. In this example +/- 3% of reading is more accurate...
