They are stated "Accurately Measures To 1/10th Of A Gallon" which means they have a digital resolution to 1/10th of a gallon. There is no stated meter accuracy so what you say may or may not be true. Since they operate by the "paddle wheel" method they are probably less accurate at low flow rates and more accurate at higher flow rates, but the reading is never scientifically accurate.
