Abstract
A multi-vortex flowmeter includes a vortex type detection device including a measurement tube provided in a flow channel to allow a fluid to be measured to pass, a vortex generator provided in the measurement tube to face a flow of the fluid to be measured, and a vortex detector for detecting a change based on a Karman vortex generated by the vortex generator. The flowmeter also includes a thermal type detection device including a temperature sensor and a heating temperature sensor, each protruding into the flow channel, and a flow rate converter, in which a pressure gauge for measuring a pressure in a pipe wired together with the vortex detector and the thermal detection device is provided integrally with the flow rate converter.
