<p>A cell for remotely sensing conductivity of a fluid passing through it, said cell comprising fluid flow path means for defining a fluid flow path, said means having an inlet and an outlet and two fluid paths between the two, thereby defining a fluid loop, an excitation transformer comprising a first toroidal core having a hole through it and wire turns around it, said core encompassing a portion of said fluid flow path means and said fluid loop therein, and a sensing transformer comprising a second toroidal core having a hole through it and wire turns around it, said core encompassing a portion of said fluid flow path means and said fluid loop, said cores being coplanar to thereby reduce leakage between said transformers.</p> |
