Abstract
A system for dispensing a volatile fluid includes a container defining an interior space for holding the fluid. The container is configured to separate the fluid into a liquid and a vapor such that at least a portion of the vapor is disposed above the liquid. The system also includes a fluid inlet, a liquid outlet, a vapor valve, a sensor, and a controller. The liquid outlet is disposed above the fluid inlet and below a liquid reference plane defined through the container. The vapor valve is configured to exhaust vapor disposed above the liquid from the container. The sensor is configured to detect a level of the liquid in the container. The controller is configured to determine the level of the liquid and actuate the vapor valve to maintain the level of the liquid at or above the liquid reference plane.
