Abstract

Systems and the related methods for the pumping of fluids through a pump. The pump comprises a pump chamber (PPN), which is responsive to applied pressures to convey fluid. The systems and methods employ control measures, implemented through the controller (16), to monitor fluid flow through the pump, using either gravimetric (246) or electrical field sensing.
