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.
