ABSTRACT:
A salt level monitoring device for water softeners including a weight for placement upon the salt mass; a drop line connected to the weight at one end and a sensor at the opposing, upper end; and a support member for supporting the sensor and drop line over the salt mass. Once the salt mass drops to a selected level, tension is placed upon the drop line and hence the sensor causing actuation thereof to send forth either an aural or visual signal. The weight has a mass less than the mass of the salt but greater than the mass of brine to prevent the weight from becoming embedded in the salt mass and to prevent false signals. A clip attaches the drop line to the weight for convenient adjustment of the drop line depth so that the salt level may be monitored at selected heights within the softener.
