とする絞り流量計。 In a throttle flowmeter, a disk-shaped throttle plate having a throttle hole in the center is inserted and held between a pair of flanges of a pipe, and the flow rate is determined by measuring the pressure difference between the upstream side and the downstream side of the throttle plate. The sealing means between the plate and the pair of flanges includes an annular groove concentric with the aperture hole, an annular metal packing made of soft metal fitted into the groove, and an annular metal packing tightly fitted into the annular groove. A throttle flowmeter characterized by a structure consisting of ridges.
