• Monitors the level (in inches of liquid, ± 1") of up to eight tanks from one central location
• Ideal for fuel, potable water, and waste water tanks - no cross contamination
• Entirely self contained - takes only 4" x 6" panel space
• Simple pneumatic operation, with no electrical connections and no risk of sparks
• Corrosion resistant for use in any boating environment
• Closed system - no fumes or odors

How It Works
Once a tank is selected by pressing the appropiate push-button valve, a very small hand pump mounted on the control panel pumps air through a dip tube into the tank. The back pressure developed by the liquid level is read on a sensitive gauge.
