So I have an inexpensive dosing pump system I purchased, its an inexpensive chinese product. The software is OK, and the pumps were mediocre at best. I had four welco pumps here at home which are very well made japanese peristaltic pumps so I thought I'd swap those into this unit. The pumps run great but even with the calibration in the software, they aren't as accurate as I'd like. So my question is, is it possible to put a very fine tuning potentiometer between the board connection and the motor so I can fine tune the speed of the motor for more accurate dosing?
Here is the doser: I Paid $60
