Claim:
1. A method for measuring a flow profile in a portion of a flow path of a turbine engine, wherein the flow path is a compressor inlet flow path; the method comprising; sensing a physical change in a plurality of hot wire mass flow sensors disposed in the portion of the flow path of the turbine engine, wherein the mass flow sensor assembly comprises at least one of a rake with a plurality of flow passages therethrough and wherein the plurality of hot wire mass flow sensors are distributed throughout the flow passages of the rake and comprises a grid defined by a plurality of intersecting diametric segments in the compressor inlet flow path where the intersecting diametric segments intersect near a center of the compressor inlet flow path on which the plurality of hot wire mass flow sensors are disposed, the physical change being related to a flow attribute at each of a plurality of locations in the portion of the flow path; and converting signals from the plurality of wires into a flow profile measurement, and the method further comprises:
