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.

[ What is claimed is:] [1.] A method of handling a fluid, the method comprising the steps of:(a) moving a tip of a nozzle below a surface of the fluid to be handled;(b) energizing a pump fluidly associated with the nozzle to move fluid into the nozzle;(c) energizing a pressure transducer fluidly ass

[ What is claimed is:] [1.] A method of handling a fluid, the method comprising the steps of:(a) moving a tip of a nozzle below a surface of the fluid to be handled;(b) energizing a pump fluidly associated with the nozzle to move fluid into the nozzle;(c) energizing a pressure transducer fluidly associated with the nozzle to monitor pressure fluidly associated with the nozzle;(d) substantially continuously monitoring pressure fluidly associated with the nozzle with the pressure transducer at least during operation of the pump, wherein the monitoring step (d) comprises monitoring pressure fluidly associated with the nozzle at a rate of about ten times per second; and(e) determining whether movement of fluid into the nozzle is intended or unintended based on the substantially continuously monitored pressure fluidly associated with the nozzle.
