Paper Abstract

A novel turbine flowmeter has been developed which by means of a fibre-optic pick-up, provides a completely passive measuring system for gas and liquid flows. A special modification to the standard rotor assembly utilises a magnetic coupling to generate a mechanical motion outside the flowmeter body. The induced periodic displacement is detected optically by a reflective sensor. A modulated signal, whose frequency is proportional to flowrate, is then transmitted via optical fibres to a remote detector. The detector unit can provide either a standard pulse output or convert the signal into flow units.
