How do you control the flow rate?

for me personally I have it set up on a relay and I am using a timer to control my flow rate

What is the volume dispensed per one revolution of the motor?

The motor shaft rolls against the 3 rollers which are rotated much slower. Theoretically the circumference of the motor shaft and the inner diameter of the tubing could be used to calculate the volume (drops) per rotation as the rollers travel 1 motor shaft circumference along the tube per RPM. I'm hoping to find a brushless motor or motor gearbox combo that is about the same RPM. I don't like brushed motors.

Is this rated for continuous duty? Reviews say no?

Not suitable for continuous duty, it is recommended to use it for less than 15 minutes at a time

Which power supply do I buy to power this unit? I know it's 12v duh!

I use it on my boat hooked to the 12v battery system. If I were using it at home, I would use a 110v to 12v "brick" from some old gizmo. I keep all my old chargers and I'll bet I've got 6 12v bricks in my old brick box: just cut off the adapter and wire it to the pump through a switch.
