ム付直動型ガバナを利用した流量測定装置。 A diaphragm that forms a valve seat in the flow path between the primary pressure and the secondary pressure, and is provided with an adjustment valve that can come into close contact with and separate from the valve seat from the secondary pressure side, and operates with a balance between the secondary pressure and the adjustment spring pressure. and the regulating valve are connected by a valve stem, and a bellofram is installed in the middle of the valve stem, and a secondary pressure introduction is provided in a pressure chamber which is separated from the primary pressure side by this bellofram and is opened into the valve stem. In a direct-acting governor with a bellows ram configured to reduce the back pressure applied to the regulating valve by introducing secondary pressure through a hole by operating the bellows ram, the pressure for detecting the pressure in the pressure chamber A flow rate measurement device that uses a direct-acting governor with a verofram, which is configured to measure the flow rate of gas passing through the governor from the pressure value in the pressure chamber indicated by the pressure gauge attached to the pressure gauge.
