Title:
DEVICE FOR CONTROLLING MASS FLOW OF LIQUID STREAM WITHIN LIQUID FLOW PASSAGE
Document Type and Number:
Japanese Patent JP2004340962
Kind Code:
A
Abstract:
To provide a device for measuring and controlling the mass flow of a liquid stream, suited for operation in ranges where flow is low.
The device for controlling the mass flow of a liquid stream within a liquid flow passage uses electrosmosis pumping to transport liquid from a reservoir through the flow passage. The flow passage is related to a thermal flow sensor means which provides an output signal for controlling pump action.
