Flow measuring device |
摘要 |
A flow measuring device includes a housing, a support, and a flow measurement element. The housing defines a passage therein and includes a passage narrowing part, which reduces a cross-sectional area of the passage, in a predetermined part of the passage. The support has a platy shape and is disposed along a flow direction of fluid flowing in the passage. The flow measurement element is located inside the passage narrowing part and is disposed on a surface of the support. The flow measurement element detects a flow rate of fluid flowing in the passage. The passage narrowing part has an inner wall surface that gradually reduces a width of the passage from a center side to both end sides of the passage in a height direction of the passage, which is perpendicular to a direction of the width of the passage. |

1. A flow measuring device comprising:
a housing defining a passage therein and including a passage narrowing part, which reduces a cross-sectional area of the passage, in a predetermined part of the passage; a support having a platy shape and disposed along a flow direction of fluid flowing in the passage; and a flow measurement element which is located inside the passage narrowing part and disposed on a surface of the support, the flow measurement element being configured to detect a flow rate of fluid flowing in the passage, wherein the passage narrowing part has an inner wall surface that gradually reduces a width of the passage from a center side to both end sides of the passage in a height direction of the passage, which is perpendicular to a direction of the width of the passage.
