摘要：Apparatus for measuring the volume of flowing fluid or gas in pipes of relativelysmall diameter. A casing having a measuring wheel therein is coupled to the pipe bymeans of a single duct pipe connection. The annular clearance within the apparatusthrough which the fluid flows is axially variable by means of an adjusting ring toaccommodate variations in the state of the fluid.
