What lengths of straight pipe are upstream and downstream from the flow meter to the next bend or valve?
What causes the pipe to not be full? Would a check valve help? Anyway, If the pipe is empty then that is the probably the best candidate for the accuracy problem.
Also, if the pump is off and on, e.g. if it is filling a tank using bang-bang control, then that means the 20kgal per day is accumulated at a much higher rates, and the low flows I mentioned earlier may not be an issue.
