A transformer board is disclosed. In some em-bodiments, the transformer board includes a base, a circuit board, a transformer having a first and second winding, a first and a second connector, a ribbon cable and a nonconductive fill material. The base has a recess within which the circuit board is positioned. The transformer is mechanically coupled to the cir-cuit board. The first connector is configured to electrically cou-ple to transducers within a pressure boundary of an ultrasonic flow meter and is electrically coupled to the second winding of the transformer. The ribbon cable is electrically coupled be-tween the first winding of the transformer and the second con-nector. The nonconductive fill material is contained by the re-cess and encases the circuit board, the transformer, the cou-pling of the first connector to the second winding of the trans-former, and the coupling of the ribbon cable to the first wind-ing of the transformer.
