1. A water conductivity sensor and indicating system comprising in combination:
- a water faucet having a base;
indicating means carried by said base and responsive to electrical signals for indicating whether the conductivity of water being delivered to said faucet is less than a preselected water conductivity;
sensing means responsive to the electrical conductance of water for generating electrical signals indicative of water conductivity; and
power consumption limiting means for limiting power consumption by said display means comprising at least one of a liquid crystal display incorporated in said indicating means and a water flow responsive switch.

Abstract
A water conductivity sensing and indicating system arranged for association with a water faucet and maintainable water processing apparatus includes apparatus for indicating whether the water conductivity exceeds or is less than some predetermined conductivity level. It also includes apparatus in the form of one or both of a flow actuated switch and a liquid crystal display for limiting battery power consumption to the end that minimum sized batteries need not be replaced oftener than the processing unit need be maintained.

11. A water conductivity sensor and indicating system for use in an installation in which supply water is delivered to a water processing unit and from the water processing unit to a faucet, the system comprising in combination:
-
indicating means responsive to electrical signals for indicating when the conductivity of water being delivered to said faucet is less than a preselected water conductivity or is less than a selected amount greater than the conductivity of said supply water; sensing means responsive to the electrical conductance of water for generating first electrical signals indicative of the conductivity of water being delivered to said faucet; Sensing means responsive to a selected one of a predetermined conductance and of the supply water for generating second electrical signals indicative of the conductivity of the selected one of said supply water and said predetermined conductance; and means for applying said first and second electrical signal to said indicating means. - View Dependent Claims (12)
