一般注記For measurement of the flow rate of liquid and gas, a turbine flow meter is widely used for its easy handling characteristics and high reliability. We however, often face, the problems of narrow covering range and electric noise. These problems are mainly caused by the electro magnetic pick-up. An optical fiber pick-up turbine flow meter (OTF) has been developed to resolve these problems by using an optical fiber pick-up instead of the conventional electro magnetic pick-up to detect the passage of turbine blades. The OTF output signal is a pulse train with a constant amplitude (1V peak) in all ranges convered. An eminent improvement of linearity is realized in the lower flow rate range. Various kinds of aeroengine start and performance tests have proved the OTF to be very useful.
