Vortex flowmeter

A vortex flowmeter comprising:

• a vortex generator;
• and a flow rate measuring unit placed downstream of the vortex generator and configured to detect a vortex generated by the vortex generator to measure a flow rate, the vortex flowmeter further comprising:
• a temperature sensing element including a metal temperature sensing case and a temperature sensor adhered to the metal temperature sensing case with an adhesive;
• a body case including:
• a body passage in which the vortex generator is placed;
• and an insertion hole in which the temperature sensing element is inserted, the insertion hole located upstream of the vortex generator, and the body passage and the insertion hole communicating with each other;
• and
• a seal member mounted to seal between the temperature sensing element and an inner wall of the insertion hole, and
• wherein the temperature sensing element inserted in the insertion hole further includes a distal end face located close to the body passage, the distal end face being placed at either a position where the distal end face is flush with a passage surface of the body passage or a position more outside than the passage surface of the body passage in a radial direction of the body passage, so that a fluid flows through the body passage while contacting the distal end of the temperature sensing element.
