System and method for pressure compensation in a pump |
| abstract |
Systems and methods for maintaining substantially a baseline pressure in a chamber of a pumping apparatus are disclosed. Embodiments of the present invention may serve to control a motor to compensate or account for a pressure drift which may occur in a chamber of the pumping apparatus. More specifically, a dispense motor may be controlled to substantially maintain a baseline pressure in the dispense chamber before a dispense based on a pressure sensed in the dispense chamber. In one embodiment, before a dispense is initiated a control loop may be utilized such that it is repeatedly determined if the pressure in the dispense chamber is above a desired pressure and, if so, the movement of the pumping means regulated to maintain substantially the desired pressure in the dispense chamber until a dispense of fluid is initiated. |
