Line 4:
== Accuracy of full scale ==
If a meter’s accuracy is based on a percentage of its full reading capability, the error is a fixed value. For example; an error of 0.5% of full scale, in a 100-gallon per minute (gpm) device is +/- 0.5 gpm. This is the uncertainty all of the time, so as you move away from the full scale capability, the 0.5 gpm error becomes a much larger percentage. At 50 gpm, you are risking a 1% error. At 10 gpm you have a potential 5% error.
the flow meters can be affected by the air pressure from the surrounding so it needs to be carefully be observed
