Abstract
Die Erfindung betrifft einen optischen Strömungssensor zur Messung einer Fließgeschwindigkeit und/oder Fließrichtung eines Fluids, insbesondere eines Gases, eines Gasgemisches, einer Flüssigkeit oder eines Flüssigkeitsgemisches, mit mindestens einem Lichtleiter. Der Lichtleiter weist eine verformungssensitive Zone auf, die in einem zu messenden Fluidstrom anordenbar ist. An einem Ende des Lichtleiters ist eine Auswerteeinheit für eine Messung einer Verformung des Lichtleiters angeschlossen.
