Abstract
An assembly comprising a fluid channel and a flowmeter, the flowmeter () comprising at least one vortex shedder () extending in the channel (C), each vortex shedder () being configured to generate Karman vortices (V) in fluid flowing through the channel (C) during operation, wherein each vortex shedder () is provided with a first fiber Bragg grating (FBG) of a fiber Bragg grating sensor (, FBG), wherein a Karman vortex frequency (fe) of the vortices (V) generated by the vortex shedder () is detectable utilizing a fiber Bragg grating (FBG) sensor signal relating to the respective first fiber Bragg grating (FBG) of that vortex shedder ().
