摘要： A method and apparatus for sensing different levels of liquids in their respective containers in a liquid-consuming and/or producing instrument system. According to a preferred embodiment, an elongated liquid-sensing probe having axially spaced electrodes adapted to sense liquid at multiple levels is arranged in each container of liquid. A controller, e.g. a suitably programmed microprocessor, operates to selectively poll different pairs of electrodes carried by the probe to determine whether or not the polled electrode pairs are immersed in the contained liquid. Preferably, the polling circuit comprises an electronically-controlled resistor that serves to normalize the level-sensing output signal for liquids of different bulk resistivity.

摘要： A liquid transfer system for transferring liquid from a plurality of containers to a plurality of destinations comprises a plurality of inlet valves. Each inlet valve is operable between an open position allowing liquid from a container to be drawn into the system and a closed position blocking liquid from a container from being drawn into the system. Liquid drawn from each of the liquid containers is delivered to a buffer chamber designed to degas the liquid in the buffer chamber. The buffer chamber leads to a vented feeder chamber that is also adapted to retain a volume of liquid. A chamber connection valve is provided between the buffer chamber and the feeder chamber to allow or block the flow of liquid between the buffer chamber and the feeder chamber. The feeder chamber is connected to a plurality of distribution valves operable to deliver liquid to a plurality of destinations.
