Abstract:
1. A flow sensor apparatus, said apparatus comprising: a flow sense element including a flow sensing bridge, wherein said flow sense element and said flow sensing bridge are mounted on a housing and together sense a mass flow of a flow path; and a seal with a conductive interconnect, wherein said seal is positioned adjacent said flow sensing bridge such that said seal with said conductive interconnect physically isolates said flow sensing bridge physically from an external environment; a signal conditioning circuit that converts a sensed flow into a proportional analog output signal, wherein said signal conditioning circuit is electrically connected to said flow sensing bridge; and wherein said seal with said conductive interconnect conducts a power signal along at least part of a path from said signal conditioning circuit to said flow sensing bridge, and conducts an output signal along at least part of a path from said flow sensing bridge to said signal conditioning circuit.
