Abstract:
1. A multi-vortex flowmeter integrating a pressure gauge, comprising: an attached measurement pipe having a flow channel formed therein; vortex type detection means comprising: thermal type detection means comprising a temperature sensor formed of a bar-shaped temperature sensor and a heating temperature sensor formed of a bar-shaped flow velocity sensor functioning as a temperature sensor and a heating sensor, each being provided perpendicular to a flowing direction of the flow channel; and a flow rate converter comprising a converter case and an amplifier board having a configuration of a microcomputer inside the converter case, wherein the attached measurement pipe has a pressure measurement portion formed upstream of the measurement tube and in a vicinity thereof, the pressure measurement portion comprises a part for housing the pressure gauge and a pressure sensing port for introducing a part of the fluid to be measured flowing through the flow channel, and the pressure gauge wired together with the vortex detector and the thermal type detection means, for measuring a pressure of the fluid to be measured flowing through the flow channel, is provided integrally with the flow rate converter at a position away from the vortex detector, the temperature sensor, and the heating temperature sensor toward an upstream side of the multi-vortex flowmeter.
