evaporation rate = 1ml/min
flow rate = 1ml/min
[ml/min] = a single number (int or float) representing the desired flow rate
[min or *] = the number of minutes to run or (*) indefinitely
A negative value for ml/min = reverse

The maximum flow rate is determined after calibration.
If the flowrate entered is too fast the EZO-PMP
TM
will send an error.
