-12- ABSTRACT A vortex flow meter includes a vibration sensing element having a sensor responsive to an external vibration and a sensor responsive to a vortex train at vertically opposite ends thereof. The sensing element is fixed to a conduit fullcrumed at an intermediate portion thereof. A vortex shedding member is integrally and oscillatably mounted in a lower portion of the sensing element. The flow meter can be assembled merely by being positioned in the conduit and, due to an integral structure, it is effectively applicable even to small diameter conduits through which fluids flow at very small flow rates. In a path along which leads from a sensor responsive to pressure variations due to vortex trains are routed to a transducer box, vibration of the transducer box is prevented from reaching the sensor via the leads, thereby rendering the flow meter less susceptive to externally derived vibrations.
