ANTI-BACKLASH MECHANISM FOR MOTOR-DRIVEN COMPONENTS IN PRECISION SYSTEMS AND APPLICATIONS

摘要

A pumping system with a pressure sensor positioned on the fill side and a pressure sensor on the dispense side to obtain and provide pressure information that can be used by a controller in determining various operating profiles. To avoid trapping air in a process fluid, a pressure sensor can be flush mounted or mounted at an angle on the sidewall of a feed chamber, a bottle, or a reservoir tank at or near the bottom or half-height. The pressure information obtained from the fill side can have many beneficial including filtration confirmation, air detection, and reduced pressure priming of a filter. The pumping system may further include a graphical user interface for displaying the operating profiles and various associated alarms in real time.
