摘要： A flowmeter can measure a small flow rate of fluid with high measurement precision, can be made small-sized, can deal with a variety of types of chemicals, and can be produced easily at a low cost. The flowmeter includes: a casing having an enlarged portion and being disposed vertically; and a float enclosed in the enlarged portion of the casing and at least partly having a detection surface. The float is to be pushed up by a fluid flowing from below into the casing and flowing upwardly in the casing. The flowmeter also includes at least one displacement sensor, disposed outside the enlarged portion of the casing, for detecting an axial displacement of the float by magnetizing the detection surface of the float.

摘要： A rotor has an interior free from invasion of water and is resistant to deformation from applied stresses normally encountered during the operation of a vacuum pump. The rotor comprises a rotor shell formed to conform to an outline of lobes and side-plates for covering transverse ends of the rotor shell. A rotation shaft is secured to the side-plates. A hollow section is formed by the rotor shell and the side-plates which is under a vacuum environment.
