1. A device for detecting an electrical current flowing through a fluid line, the device comprising:
a magnetically conductive core with a centrally located support member configured to receive a length of coiled conductor, and
at least two electrically conducting coils located at positions that are spaced from the centrally located support member on opposite sides thereof, wherein
the magnetically conductive core comprises a magnetically conductive central branch on which the centrally located support member is disposed in surrounding relationship and a pair of magnetically conductive outer branches with at least one of the electrically conducting coils disposed in surrounding relationship to each of the outer branches, and
the centrally located support member comprises a spool which surrounds the magnetically conductive central branch.
