Built to survive wet, corrosive, aggressive environments, TANK ALARM comes with 10 ft long piggyback cord and mounts directly on tank with 2 in. NPT thread. Liquid level is maintained automatically between high and low float switch, which cycles pump on and off. If level gets too high, third float switch triggers high-visibility flashing beacon light and audio buzzer. Adjustment of working depths for high/low level control points is done instantly and without any tools using thumbscrews.
