Abstract

PURPOSE:To obtain a flowmeter having a large amount of detection output and self-cleansing effect of the flow detecting sensor in a simple constitution, by detecting the reverse current of the same cycle as the Karman vortex by the sensor provided on the area of the rear end wall of the Karman vortex generator. CONSTITUTION:Karman vortex 7 is generated by vortex generator and in the cycle proportional to the fluid flow rate of the air or the like. Thus intense reverse current 8 having the same cycle as the generation of the Karman vortex and the varying direction is generated. Then the generating cycle of vortex 7 is detected according to the variation of resistance based on the change of temperature at or near the rear end of generator 1 and via a sensor consisting of hot film 3 provided at the center part of generator 1, conductive films 4 and 4 connected to film 3, lead wire 5 connected to films 4 and 4 at the area where no effect is given to the flow, and others. With use of the intense reverse current having the direction varying according to the time, a Karman vortex flowmeter having a large amount of detection output and self-cleansing effect of the sensor can be realized in a simple constitution.
