Before Tank Tender, you had to rely on, an old-fashioned dip stick, site glass or electric float gauge to check the level of your boat's fuel, water or holding tank. Not anymore.
Tank Tender provides extremely accurate readings for up to ten tanks. Without electricity. Without leaving the bridge. Without a doubt.
Tank Tender operates on air pressure. Select the tank, then pump a small amount of air through tubing to the bottom of the tank. When the air pressure in the tube equals the liquid pressure at the bottom of the tank, the gauge displays this pressure in inches of liquid.

It's convenient. Monitor the levels in all tanks with just one instrument.
It's easy to use. You can select a tank to measure and get an accurate measurement from the bridge in two or three seconds.
It's simple to install. The average 4-tank system takes about an hour. And there's nothing to wire.
It's surprisingly inexpensive. Tank Tender costs much less than other industrial systems offering similar accuracy and reliability, and only slightly more than conventional electric gauges.


4 Tank Instrument	10 Tank Instrument

This is the back of the 10 tank instrument. Looks simple? It is. That's because the Tank Tender was designed for maximum reliability, accuracy and zero maintenance.

Tank Tender's components have proven reliability in medical and dental applications. Only precision valves, pumps and easy-to-install push-in connections are used.

Tank Tender gauges are available in scales of 30" or 60" and are calibrated for inches of water and inches of diesel fuel (other scales are available by special order).

As you can see by the photo, installation is a simple procedure.

All you do is drill a small hole (5/32" ) in the top of the tank. Then tap with a 10x32 thread and screw the "O" ring sealed / "banjo" fitting onto the tank top. The 1/8" nylon tubing is specially extruded to extend straight to the bottom of the tank.

A typical 4-tank installation may read the contents of one fuel, one holding and two water tanks. There is no chance what so ever of contamination because the tubing in the tanks carries only air, fluid is never removed from any tank.
