摘要： In a method for monitoring fluid flow sensing a first sensed variable such as the differential pressure of the fluid flow as at least an indirect function of the fluid flow to be sensed and a second sensed variable such as the vortex shedding frequency at a bluff body located in the flow as at least an indirect function of the fluid flow and different from the first sensed variable is detected and/or determined; the first and second sensed variable are simultaneously detected and/or determined on the basis of one and the same basic physical sensing principle; and the first and second sensed variable are compared to each other.
