The present system generally relates to a fluid flow system where a controller and motor pump assemblies are used to optimize the control of fluid flow through the system. The controller samples the back electromotive force of the motor and pump assemblies and is able to utilize the sampled back electromotive force in conjunction with predefined target back electromotive force values, preferably empirically determined and tuned to an induvial motor and for a select fluid, to tune the voltage applied to the system, control the back electromotive force of the system and, by extension, control the flow of fluid.

G05D 7/06 - Control of flow characterised by the use of electric means
A compact, modular dosing pump system that is capable of microdose and macrodose volume flow rates, reduces or eliminates the need for additional flow control components such as temperature and pressure sensors, and utilizes a wider operational flow range than existing systems while maintaining the level of accuracy and precision exhibited by conventional dosing pump systems is provided. The dosing pump utilizes a a control system to deliver a range of fluid volumes. The control system monitors the motor emf voltage, calculates the flow rate, and makes adjustments to the pump motor voltage to precisely maintain the desired flowrate.

A compact, modular dosing pump system that is capable of microdose and macrodose volume flow rates, reduces or eliminates the need for additional flow control components such as temperature and pressure sensors, and utilizes a wider operational flow range than existing systems while maintaining the level of accuracy and precision exhibited by conventional dosing pump systems is provided. The dosing pump utilizes a pump and flow circuit, and a control system may be used to deliver a range of fluid volumes. The flow circuit utilizes a networked system of fluid paths and valves to route fluid through the dosing pump system in response to a pressure differential between fluid inlet and fluid outlet ports, while the controller monitors and controls the operation of the system.
