Device for detecting the mass of a flowing fluid

The present invention relates to a device for detecting a mass of a flowing fluid, and in particular to a device having electronic components with conductive lead frames for communicating electrical signals to and from electronic components, such as integrated circuits and resistive elements. 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.
