Abstract

PURPOSE:To obtain the transducer for flow rate measurement simple in the constitution and advantageous in explosion-proof, by locating the optical material inside the detection rod such as Karman vortex producing body and detecting the change in optical property of optical material with light via optical fiber. CONSTITUTION:In case of vortex flowmeter, the detection rod 2 being the vortex production body is fixed in the tube path 1 flowing in liquid, for example, with the screw 3 and the flange 4, and the mirror 51, optical material 52, poralizer 53, and one end of optical fiber 6 are fixed to the concave 21 of the detection rod 2 by flowing the molten glass 7. When the fluid flows to the optical material 52, Karman vortex is generated and when floating force is given to the detection rod 2, the optical property of the optical material 52 is changed. Further, when the light from the laser diode 8 is irradiated to the mirror 51 via the optical fiber 6, the light passing through the optical material 52 at the reflection on the mirror 51 is the optical frequency signal corresponding to the change in floating force, then this light is transmitted to the laser diode 8 to convert into pulse signal and the flow rate of liquid is obtained by counting it.
