Paper Abstract

The deflection of a flexible cantilevered optical fiber is used to measured the flow of gases and fluids. For practical applications a combination of an emitting optical fiber with a half-shade edge and a positional sensitive diode (PSD) is used. For a PSD with a length of 3 mm a range of measurement of 1:500 and more is possible. The responsivity of this device is 10 ml/s. The effects of deflection caused by the mass of the fiber are compensated for by using a second fiber of equal length in a separated compartment in the sensor device.
