A flowmeter has two moving parts, a rotor with a cylindrical core and the radially extending sinusoidal curving vane. A slider has a gate opening which fits on the vane for reciprocating axially as the rotor turns. The slider and rotor are held within a cavity and slider recess within a case. Fluid is admitted through an inlet opening on one side of the slider and is exhausted through an outlet opening on the other side of the slider. A magnetic pickup on the slider indicates the movements of the slider, and hence the rotation of the rotor and the volume of fluid flowing through the meter.
