A flowmeter with an optical pick-off includes a turbine and a swirl generating impeller having magnets mounted on their periphery. Positioned on the exterior of the flowmeter housing in line with the magnets are monolithic Faraday effect optical switches. Each time the magnets pass by its associated Faraday switch the switch is actuated to produce an output pulse.
