ABSTRACT:
A flowmeter, particularly for measurement of fuel flow rates to engines having a bore within a body with axially disposed inlet and outlet parts, a rotor in the bore with a hub carrying helical vanes substantially filling the cross-section of the bore and a light source with an associated photo responsive device arranged so that the vanes of the rotor interrupt the light beam to produce an electrical output signal with a frequency component proportional to the speed of rotation of the rotor.
