In a flow meter, a cylindrical member containing therein a vane wheel is fitted in a measuring chamber of a casing so as to be closely in contact with the peripheral wall of the casing, and a cover is put on the cylindrical member. Rectangular inlet and outlet nozzles in a side wall portion of the cylindrical member communicate with inlet and outlet ports of the casing, respectively. A pivot supporting the vane wheel is replaceably attached to a bottom portion of the cylindrical member. A supporting shaft of the vane wheel extends upward through a center opening in the cover to be connected to a measuring mechanism.
