Abstract
A flow measurement device includes a bluff body in a flow path in a measuring pipe to generate Karman vortices downstream of the bluff body, and a temperature sensor downstream of a piezoelectric element for sensing a change in the Karman vortices by converting the change into an electrical signal. A flow rate of a fluid can be corrected based on a relation of a vortex shedding frequency at a temperature of the fluid measured with the temperature sensor and a vortex shedding frequency of the fluid measured at a reference temperature.
