Monty,
I did the promised test today. The "out" position
of the control arm is indeed the low flow rate. However, if it is all the way
out, meaning at the lowest position sensor reading, the pump is totally off.
I measured at full open with the position sensor
reading 1.758k, 40cc at an arbitrary RPM and run time. At a low setting of
913ohm, and the same RPM and time, the amount was 9cc.
On the adjuster I have designed, I will specify a
height of the setting screw for min and max flow.
