  • Patent number: 11307076
    Abstract: In this vortex flowmeter provided with a vortex generator and a flow rate measuring unit, a seal member is mounted on a temperature sensing element including a temperature sensor adhered with an adhesive to a metal temperature sensing case. The temperature sensing element is inserted into a first insertion hole formed in a body case so as to communicate with a body passage. A distal end surface of the temperature sensing element is arranged in either a position where the distal end surface is flush with the passage surface of the body passage formed in the body case or a position more outside than the passage surface in the radial direction of the body passage.
