    • PROBLEM TO BE SOLVED: To provide a flow control device that can control flow rate using a single sensor.SOLUTION: A control device (30) comprises: an inlet (32) for receiving a flow; an outlet (34) for directing the flow to other components of a flow system; a pressure reduction element (36); a pressure sensor (38) located upstream from the pressure reduction element (36) configured to measure upstream pressure; a pressure sensor (40) located downstream from the pressure reduction element (36) configured to measure downstream pressure; a controller (42), which can comprise a processor, a memory and software instructions for determining fluid flow rate and generating a valve control signal; and a valve (44), such as a butterfly valve and a hydraulically driven valve, responsive to the valve control signal to regulate fluid flow.
    • 要解决的问题:提供可以使用单个传感器来控制流量的流量控制装置。 控制装置(30)包括:用于接收流动的入口(32); 用于将流引导到流动系统的其它部件的出口(34); 减压元件(36); 位于所述减压元件(36)上游的压力传感器(38),其被配置成测量上游压力; 位于所述减压元件(36)的下游的压力传感器(40),其构造成测量下游压​​力; 控制器(42),其可以包括处理器,用于确定流体流速并产生阀门控制信号的存储器和软件指令; 以及响应于阀控制信号来调节流体流动的阀(44),例如蝶阀和液压驱动阀。 版权所有(C)2013,JPO&INPIT
