Fluid control system

摘要

The fluid control device of the present invention combines a flow sensing unit in series with a control valve. The flow sensing unit is of the displacement piston type and the flow rate is electronically sensed. A single action poppet valve assembly facilitates the use of a self contained power supply for use in remote locations. A microprocessor monitors parameters including pressure, flow rate, temperature and flow volume, and is enabled to activate the control valve to the open or shut positions based upon any combination of the monitored parameters.
