Lead frame for automotive electronics

A device for detecting a mass of a flowing fluid, the device comprising:

• a housing having a fluid sampling portion and a circuit cavity portion, wherein the fluid sampling portion is positionable within a fluid carrying duct and includes a flow passage;
• a nozzle in fluid communication with the flow passage, wherein the nozzle has a plurality of longitudinally converging elliptical side surfaces that terminate at a nozzle exit;
• a first electrical element disposed in the flow passage at the nozzle exit;
• a second electrical element supported by the housing external of the flow passage;
• a circuit module in communication with the first and second electrical elements and disposed in the circuit cavity portion for detecting a change in an electrical property of the first and second electrical elements, wherein the detected change in the electrical property are used to determine the mass of the flowing fluid;
• and
• 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.
