What is the typical accuracy of thermal mass flow meters?
Suppliers have improved the accuracy of thermal flow meters in recent years. While some thermal flow meters may achieve accuracy levels of 1 percent, other thermal flow meters have accuracies in the 3-5-percent range. Users who are considering thermal flow meters need to balance their accuracy needs with their cost requirements. For example, while not as accurate as Coriolis flow meters, thermal meters offer a significantly lower price point.
