| description | PROBLEM TO BE SOLVED: To provide an in-line type steam flowmeter which is not required to protect a pressure-receiving diaphragm surface by supplying such liquid as water from outside at plant start-up, less liable to cause stagnation of foreign material and is superior in attaching performance. SOLUTION: The steam flowmeter 1 detecting flow rate of steam flowing through a pipe comprises a throttle mechanism 110 attached to the pipe, a pressure-receiving part having a diaphragm 122 for detecting the differential pressure of the steam flowing through the throttle mechanism and attached to a part above the throttle mechanism 110 in a state of being attached to the pipe of the steam flow meter, a flange cover 121 covering the diaphragm surface of the pressure-receiving part and forming a space for liquid stagnation, when the steam is liquified inside by cooperation with the diaphragm surface, and an inlet pipe 130 for introducing the steam from the throttle mechanism 110 to the upper part of the space for liquid stagnation, which is connected to the throttle mechanism 110 at one end and to the upper part of the flange cover 121 at the other end.
