Filed:

Jul 3, 2003

Appl. No.:

10/613257

Scott Lee Straight - Livonia MI
Eric Christopher Myers - Howell MI
James Driscoll - Sterling Heights MI
Ralph James Ross - Wixom MI

Assignee:

Vistoen Global Technologies, Inc. - Dearborn MI

International Classification:

G01F 500

US Classification:

732025

Abstract:

A mass fluid flow sensor for determining the amount of fluid inducted into an internal combustion engine, for example, is disclosed. The mass fluid flow sensor includes an external intake fluid temperature element which improves the accuracy of the mass fluid reading. An external cold wire element is further provided which improves response time. The mass fluid flow sensor has an improved aerodynamic design which provides a lower system pressure drop. Moreover, the sensor is smaller and lighter and has fewer parts, thus providing better manufacturability. A molded one-piece isolated jet nozzle having a hot element disposed therein is included in the fluid sampling portion. Consequently, an improved lower internal flow passage pressure drop is achieved. Additionally, an improved signal to noise ratio, as well as a larger dynamic range is an advantageous consequence of the present invention. The present invention further provides improved electromagnetic interference performance.

International Classification:

G01F 168

US Classification:

7320422

Abstract:

A device for detecting a mass of a flowing fluid is disclosed. The device includes a housing having a fluid sampling portion and a circuit cavity portion. The fluid sampling portion is positionable within a fluid carrying duct and includes a flow passage. A nozzle is in fluid communication with the flow passage, wherein the nozzle has a nozzle exit. An electrical element is disposed in the flow passage proximate to the nozzle exit. Further, a circuit module is in communication with the electrical element and disposed in the circuit cavity portion for detecting a change in an electrical property of the electrical element, wherein the detected change in the electrical property is used to determine the mass of the flowing fluid. Finally, a homogenous lead frame having a connector pin portion and an electrical attachment portion for providing an electrical path from the electrical element and circuit module to the connector pin portion is provided.
