A feed value for the water property concentration is measured in a feed water stream entering the flow-through capacitor. An amperage of the flow-through capacitor and a flow rate through the flow-through capacitor is controlled to remove ions from the feed water stream to achieve the desired removal of the water property.

Conductivity sensor for an ion exchange water softener
A water treatment system includes a tank that contains a particle bed for removing minerals from water flowing through the tank. The regeneration of the particle bed is conducted in response to measuring its conductivity. A probe is provided for that measuring. That probe has a sleeve with a tubular portion for extending through and engaging a wall of the tank. A probe body is removably received within an aperture of the sleeve and includes a pair of electrodes that project inside the tank. A retainer that secures the probe body within the sleeve. Different mechanisms are provided for securing the sleeve to the tank depending upon the particular materials used to fabricate the tank.
