Didn’t think about that yet. But yes - accuracy is crucial in dosing. I think that we need sometning as low as 1 ml of dosage as minimum amount. And we need it accurate - not 0,8 or 1,2 but 1ml exactly. (or gallon units equivalent for nonmetric systems).
Question is - can non stepper motors on already completed dosing pumps be accurate enough? Or do we need perfect stepper motor dosing pumps, which can be more expensive?
