Peristaltic Pumps Information

[louieho]

Hi,
Does anyone have any information or know where I can find information on the analytical model of a peristaltic pump? I am trying to design a controller for a Peristaltic pump by monitoring the flowrate and back pressure.
Any help and/or reference would be great.

Thank you.

Regards,
Louie

Flexicon is one of the best manufacturers of peristaltic pumps for pharmaceutical application where you require precision filling particularly at low fill volumes. Visiting their website may help you.

Thank you quark. But we already have a precision low volume pump. The problem is that we would like to automate the pump flowrate calibration as well as flowrate correction over the life of the tubing. We are hoping to compensate for the drift by speeding up the motor when the tube age. Since the behavior can differ a little from the way the pump is used and the condition of the environment, we decided to feedback the flowrate for flow adjustment. As such, I am trying to see if there is anything papers, or boooks or website that have some kind of mathematical model that I can use to simulate the Plant to calculate my controller numerically.
