Claims

[Scope of utility model registration request]

In a flow rate/flow rate detection device that provides a vortex generator in a flow path of a fluid to be measured and detects a vortex generated in the fluid to be measured by the vortex generator to detect the flow velocity or flow rate of the fluid to be measured, the vortex generation A pair of pressure introduction passages each having one end open in the passage portions on both sides of the body are extended substantially parallel to each other to the outside of the passage, a sealed space is formed outside the passage, and one end is opened in the sealed space. A bottomed guide member is disposed, a partition is held on the guide member so as to be displaced in response to pressure changes, and a pressure detection chamber is defined between the partition and the bottomed part of the guide member. , the other end of the pressure introduction path of the pair of pressure introduction paths is communicated with the sealed space, and the other end of the other pressure introduction path is connected at a position where the other end opening faces the center portion of the partition wall. 1. A flow rate/flow rate detection device, comprising a sensor communicating with a pressure detection chamber and detecting displacement of the partition wall.
