Abstract
An integrated pump and meter having a spindle axially extending in the direction of the flow of fluid for pumping and metering the flow of fluid. A volume of fluid pumped is calculated as a function of spindle rotation. In one particular of embodiment, a pair of pressure sensors are located at the inlet and outlet of the pump/meter, respectively for computing a gap loss volume due to fluid passing between the pump/meter spindle and the cylinder wall. The gap loss volume and calculated flow volume are combined to calculate a total volume of fluid to be dispensed.
