Imagine this. You order a guage that measures from 1-100GPH flowrates.
Your actual flow rates in your system are 2GPH
It's going to be kinda hard to read the guage because the resolution on the guage will be so coarse. The little float ball will look as tho it hasn't even moved from the bottom of the scale.
What you would want is a guage that would read from like 1-5GPH which would put the little float ball almost in the middle of the guage where it's easy to get a more accurate reading.
