SN53B series intelligent vortex flow temperature sensor is based on the principle of Karman vortex street,
Karman Vortex Street was observed and studied by American Hungarian scientist von Karman in 1911
Phenomenon investigated: When the fluid bypasses a non fluid linear object, the left and right sides of the object wake
A pair of antisymmetric vortices that are alternately arranged in opposite directions of rotation. this
The generation of vortices is periodic and alternant, and the change frequency is related to the fluid
The velocity is proportional, which is the Karman vortex street phenomenon. The specific relationship is
Sr=fd/V。 Vortex street flowmeter is to use the nature of this phenomenon to measure the vortex
The shedding frequency of the flow determines the velocity or flow rate of the fluid and supports the flowmeter.
