Abstract
A system and method for pumpless delivery of a product are provided. The system generally utilizes one or more containers each containing a fluid, and sensor(s) configured to detect a velocity of the fluid in an output line from the container(s). A controller is configured to control one or more valves using velocity or flow rate data received from the sensor(s) in order to control the flow of fluid(s) from the container(s). A source for generating a pressure differential, generating either a higher pressure or lower pressure than what is in each container, may also be present.
Claims28
A system for pumpless delivery of a product, comprising:
- at least one container, each container enclosing an associated fluid, the at least one container operably coupled to a gas;
- at least one sensor configured to detect a flow of the associated fluid in an output line from the at least one container;
- and
- a controller in communication with the at least one sensor, the controller configured to control at least one valve using a velocity or a flow rate based on a voltage from the at least one sensor.

A method for pumpless dispensing, comprising:
- receiving voltage data from a sensor as a fluid is flowing past;
- determining a velocity, a mass flow rate, or a volumetric flow rate from a container based on the voltage data;
- and
- adjusting a valve based on the velocity, a mass flow rate, or a volumetric flow rate.
