Flowmeter-volume meter counting revolutions of mobile body - has two flanges each with groove forming portion of revolution channel and either inlet or outlet passage

摘要

The flowmeter volumeter counts the revolutions of a mobile body in a revolution channel into which open a fluid inlet passage and a fluid exhaust passage. A first flange has a revolution groove which is a first portion of the channel and is grooved with one or both passages. A second flange has a revolution groove which is a second portion of the channel and is grooved with the other passage. Both flanges are connected by a fastener arranged for allowing a rotation displacement relative to each other, in order to be able to adjust the distance between the openings through which both passages open into the channel.
