Abstract
A method of measuring fluid flow in a system includes providing a fluid supply assembly which includes a fluid supply supplying fluid, a dispensing valve from which the fluid is dispensed, a dispensing line connecting the fluid supply to the dispensing valve, a gear pump including a motor and a gear being rotated by the motor to provide a flow of fluid from the fluid supply to the dispensing line, a revolution counter counting a number of revolutions of an element of the gear pump, a pressure transducer coupled to the dispensing line sensing pressure in the system, and a controller including a processor and a memory to control the system. The method further includes directing fluid from the fluid supply, rotating the gear to provide the flow of fluid from the fluid supply to the dispensing line, and providing a calibration process by modulating the gear pump.
