1. A flow-through conductivity sensor, the sensor comprising:

  • a flow conduit;

    first and second electrodes disposed relative to the flow conduit to contact process fluid proximate the conduit and convey an electrical current between the first and second electrodes through the process fluid;

    a current return conductor coupled to the first and second electrodes; and

    at least one toroid arranged to interact with the current return conductor to measure current flowing between the first and second electrodes through the process fluid provide an indication of process fluid conductance.
