Abstract
It is an object to provide a vortex flow meter with less measurement errors caused by a temperature change, a pressure change, and a mechanical vibration, and capable of performing a precise measurement regardless of conditions, in addition, to provide a vortex flow meter capable of sufficiently preventing corrosive chemicals that is a fluid to be measured from leaking from a measurement pipe line due to corrosion.A vortex generator that generates the Karman vortex and a measurement pipe line in which a holder body housing a detecting element that detects an alternating force of the Karman vortex is disposed are made of a material having a small coefficient of linear thermal expansion such as a quartz glass, and the vortex generator and the holder body are fixed to the measurement pipe line by welding in an integrating manner.
