When it comes to flowmeters, there are some pretty hot opinions in the control and instrumentation world about the inaccuracies of an analog totalizer, and why using a pulse-driven counter/totalizer is the way to go.

After reading some really vicious web debates on the topic, I had the opportunity to test for myself, and I was surprised at how close the resulting totals were, and how insignificant the error was.
