what is the working principle of vortex flowmeter
Answer Posted / visakh pradeep
An obstruction in a fluid flow creates vortices in a
downstream flow. Every obstruction has a critical fluid
flow speed at which vortex shedding occurs. Vortex shedding
is the instance where alternating low pressure zones are
generated in the downstream.These alternating low pressure
zones cause the obstruction to move towards the low
pressure zone. With sensors gauging the vortices the
strength of the flow can be measured.
