Claims (1)
差を演算して流量操作出力を発信する流量調節計
と、上記操作出力を受けそのレベルに応じて切り
換えられて上記管路の流量を制御する並列接続さ
れた大流量制御弁及び小流量制御弁とよりなる流
量制御装置において、上記操作出力と上記小流量
制御弁との間に増幅手段を介在させたことを特徴
とする流量制御装置。 A flow controller that inputs the measured flow rate value and set value of the pipe line, calculates the deviation between them, and sends a flow rate operation output, and a flow rate controller that receives the above operation output and switches according to its level to control the flow rate of the above pipe line. A flow control device comprising a large flow control valve and a small flow control valve connected in parallel, characterized in that an amplifying means is interposed between the operation output and the small flow control valve.
