ABSTRACT:
A turbine wheel flow measuring transducer having a reaction turbine wheel measures low flow rates of a gas. A disk (D) is rotatably mounted in a chamber (C) formed within a housing (H) through which the gas to be measured passes through a nozzle assembly (N). Plural teeth (T) are formed around the periphery of disk (D) for receiving the impact of the gas from nozzle assembly (N). A photoelectric circuit (P) directs light onto side portions of disk (D) to measure the relative movement of disk (D) in response to the impact of the gas against teeth (T).
