Abstract
A low water indicator (10) comprising an indicator module (12) comprising a control unit (18); a submersible housing (14) with a low water detector (20) connected to said control unit through a cable (16); wherein: a sloping top surface (30) of said submersible housing is formed as a truncated cone with a smaller top area (32), the cable extends from the top area (32), and the low water detector (20) comprises two terminals (20a, 20b) exposed on said sloping top surface (30) below the top area (32); and wherein the control unit (18) is configured to activate the indicator module (12) when the low water detector (20) detects absence of water between the terminals (20a, 20b).
Claims16
A low water indicator comprising:
- an indicator module comprising a control unit;
- a submersible housing with a low water detector connected to said control unit through a cable;
- wherein a sloping top surface of said submersible housing is formed as a truncated cone with a smaller top area, the cable extends from the top area, and the low water detector comprises two terminals exposed on said sloping top surface below the top area;
- and
- wherein the control unit is configured to activate the indicator module when the low water detector detects absence of water between the terminals.
A method of detecting and indicating absence of water by detecting existence and absence, respectively, of a current flow in water between two terminals and producing a flashing signal when the absence of current flow is detected, wherein said two terminals are arranged extending from a submersible housing.
