Abstract
The present disclosure relates to systems and methods for monitoring the fill level of salt in a brine tank of a water softener system. Distance measurements may be taken by a wireless-enabled smart sensor device disposed at an interior surface of a brine tank cover. Calibration of the smart sensor device may include taking distance measurements corresponding to different fill levels of the brine tank, obtaining at least one corresponding user-defined fill ratio, and storing these as calibration data. Subsequent distance measurements may be used to determine a current fill ratio based on the calibration data. If the current fill ratio is below a threshold value, an alert may be sent to the user device indicating that salt should be added. If the current fill ratio is above a previous fill ratio, an alert may be sent to the user device requesting recalibration of the smart sensor device.
