ABSTRACT:
A turbine wheel flow measuring transducer is provided for measuring low flow rates of corrosive fluids, whether fluids or gases. The transducer has a turbine wheel rotating in a housing fluid chamber at a rate set by the corrosive fluid flowing through the housing. Infrared light from an optical flow measurement circuit passes through spaced holes in the rotating turbine wheel. The amount of light which passes through the wheel indicates flow rate. The housing is made from a corrosion resistant synthetic resin which is also translucent to infrared light from the light source. The light source thus need not be in the housing fluid chamber, materially simplifying the transducer. Further, the turbine wheel is provided with an improved bearing support so that problems of thermal expansion of the housing are overcome.
