摘要：A flow rate regulating valve is mounted on a pipe for passing therethrough thefluid to be controlled.The fluid pressure is detected at the primary side and thesecondary side of an orifice provided within the pipe. The fluid temperature is alsomeasured in the vicinity of the pressure measuring location. The flow rate is calculatedbased on the primary and secondary pressures and temperature detected. The degreeof opening of the valve is controlled in a direction to decrease the deviation of thecalculated flow rate from the flow rate setting in accordance with the deviation and thepolarity thereof.
