Abstract
Various methods, apparatuses, and systems for improving sensitivity and performance of a flow sensing apparatus are provided. The flow sensing apparatus includes: a housing defining an inlet port and an outlet port; a sensing element disposed at least partially within the housing; a main flow path defined within the housing connecting the inlet port and the outlet port, where the main flow path is disposed proximate the sensing element such that at least a portion of the flowing media is in fluid contact with the sensing element; and a laminarizing structure located in the inlet port and configured to direct a flowing media in a laminar flow pattern.
Claims17
A flow sensing apparatus, comprising:
- a housing defining an inlet port and an outlet port;
- a sensing element disposed at least partially within the housing;
- a main flow path defined within the housing connecting the inlet port and the outlet port, wherein the main flow path is disposed proximate the sensing element such that at least a portion of a flowing media is in fluid contact with the sensing element;
- and
- a laminarizing structure located in the inlet port and configured to direct the flowing media in a laminar flow pattern, wherein the laminarizing structure comprises a plurality of fins around the inlet port and the outlet port, the fins around the inlet port extending between the inlet port and the main flow path to direct the flowing media in the laminar flow pattern.
A flow sensing system, comprising:

- a sensing element disposed at least partially within the housing;
- a main flow path defined within the housing connecting the inlet port and the outlet port, wherein the main flow path is disposed proximate the sensing element such that at least a portion of a flowing media is in fluid contact with the sensing element;
- and
- the main flow path has a tapering cross-section from a position connecting with the inlet port to a position contacting the sensing element;
- a laminarizing structure located in the inlet port and configured to direct the flowing media in a laminar flow pattern, wherein the laminarizing structure includes a plurality of fins around the inlet port and the outlet port, the fins around the inlet port extending between the inlet port and the main flow path to direct the flowing media in the laminar flow pattern.
