There is provided a flow transducer and method to sense flow of a fluid. The flow transducer includes a housing defining an internal passage way therethrough. A flow rate apparatus is disclosed in the internal passageway. The proximity sensor is coupled to the housing, with the proximity sensor aligned radially with the flow rate apparatus. A pair of annular conductor-insulator assemblies are coupled to an outer surface of the housing, with each conductor in electrical communication with the proximity sensor. A cap is coupled to the housing and is configured to axially secure the conductor-insulator assemblies to the housing, with the cap defining an orifice axially aligned with the internal passageway. The proximity sensor is configured to produce an electrical signal as the flow rate apparatus rotates past the proximity sensor, the electrical signal corresponding to the flow of the fluid through the flow transducer.
