Publication number: 20140013839Abstract: An apparatus for detecting salt level within a water treatment system is provided and includes a biasing member, a paddle operatively connected to the biasing member, and an actuator operatively connected to the biasing member. The biasing member biases the paddle in a first position when the salt level is below the bottom of the paddle. The paddle is configured such that when the salt level is above the bottom of the paddle sufficient force from the salt is applied to one of the sides of the paddle to overcome the biasing force of the biasing member and move the paddle to a second position. The actuator is configured to cause a signal to be outputted that indicates that the salt level needs to be replenished in response to the paddle being in the first position.Type: ApplicationFiled: September 12, 2013Publication date: January 16, 2014Applicant: Chandler Systems, Inc.Inventor: William D.
