A sealed sensor housing for use in measuring the concentration of an additive or impurity in gasoline comprises a housing body of metal formed by a deformation process with no substantial machining, and the housing body is joined together with an inlet tube, an outlet tube and an electrode such that the electrode is hermetically sealed in the housing body. Two pairs of long straight pontoons, each having five articulated short pontoon segments, support an upper framework formed by six articulatable legs, three on either side. The system allows for parsing source data fields, defining new source data fields, combining source fields to create source field combinations, and combining destination fields to create destination field combinations.
