Abstract
A solid product level indicator (100) for determining the specific gravity of a use-solution (120) thereby indicating the concentration of the solid product (123) dissolved in the use-solution (120) includes a float assembly (125). The float assembly (125) includes a float (101) and a float stem (102). A guide member (104, 106 and 108) positions and guides the float (101). Magnets (114) contained inside the float (101) trigger a signal mechanism (112) inside the float stem (102) when the float (101) is displaced along the stem (102) due to the decrease in the specific gravity of the use-solution (120) when the concentration of the solid product (123) is low. The float assembly (125) can be positioned to provide early or late alert to allow replenishment of the solid product (123) before the supply of solid product (123) is critically low. The solid product level indicator (100) can be used in systems with constant liquid levels or variable liquid levels.
