Abstract
Methods of fluid handling are disclosed. According to one method, a tip of a nozzle is moved below a surface of the fluid to be handled. A pump fluidly associated with the nozzle is energized to move fluid into the nozzle. A pressure transducer fluidly associated with the nozzle is energized to monitor pressure within the nozzle. Pressure within the nozzle is substantially continuously monitored with the pressure transducer during operation of the pump. Based on the substantially continuously monitored pressure within the nozzle, it is determined whether movement of fluid into the nozzle is intended or unintended. Similar methods may be used to move fluid out of the nozzle.
