Abstract
Methods of fluid handling are disclosed. In one method, a nozzle is moved adjacent a container for a fluid. A pump fluidly associated with the nozzle is energized to move fluid with respect to the nozzle. A pressure transducer fluidly associated with the nozzle is energized to monitor transient pressure fluidly associated with the nozzle. The transient pressure fluidly associated with the nozzle is substantially continuously monitored with the pressure transducer at least during operation of the pump. It is determined whether movement of fluid with respect to the nozzle is intended or unintended based on the substantially continuously monitored pressure fluidly associated with the nozzle.
