syringe pump controller

plj

Hi,
I'm new into this forum. I'm planning to do a syringe pump controller to be used with a Labview software. As far as i know, precision flow rate movements higly depends on having the right stepper motor being used. Has anyone done anything similar on this? I'm looking for the right stepper motor specs to be used on this, and exactly how do i get a reading of the movement by the stepper motor to be read by the Labview via a data aquisition device.
Any ideas or suggestions are welcome.
Thanks.
