  • Mass flowmeter
    Patent number: 4630484
    Abstract: A mass flowmeter has a vortex generator for shedding a Karman vortex street downstream of the vortex generator positioned inside a duct for guiding a fluid. The vortex generator comprises a stationary member and a movable member which is displaceable in relation to the stationary member. The movable member is displaced by the expanding or contracting of bellows in response to changes in pressure and temperature of the fluid to thereby vary the characteristic dimension of the vortex generator. The Karman vortex shedding frequency of the vortex generator is measured by a heat-wire type sensor.
