Mass flow accuracy
(1)
(1) Stated flow accuracy includes the combined effects of repeatability, linearity, and hysteresis. All specifications for liquids are based
on reference conditions of water at 70 °F (21.1 °C).
Standard

% of rate, whichever is greater
Optional
±0.5% of rate or
% of rate, whichever is greater
