Questions and Answers

How does it work?

The tank tender operates on air pressure. It pumps a small amount of air through tubing to the bottom of the tank. The excess air pressure bleeds off until the air pressure in the tube equals the liquid pressure in inches of depth, to be interpreted in gallons of fuel or water (water weighs 8.35 pounds to the gallon and diesel weighs 7.18 pounds to the gallon).

Is it easy to install?

Yes. Installation is simple and requires no special tools. The tank penetration fitting requires only one small hole (5/32") tapped to a 10 x 32 thread. Usually less than a five minute job.

What is the accuracy?

The Tank Tender is accurate +/- 1% at mid scale on a proper installation. This is 3 to 4 times the accuracy of conventional electric gauges.

Is it reliable?

Yes. Since the system operates on air pressure (pneumatic), its reliability far surpasses that of most conventional electric gauges.

Can I mix fluid readings on the same unit?

Yes. A typical installation reads both water and diesel tanks. Since the tubing from the tank contains only air and never removes any fluid from a tank, it is safe to mix the type tanks measured on a single system.

Can I monitor a holding tank?

Yes. We have recently added the OPTION of a "purge" valve toggle switch for holding tank applications. This allows the air to bypass the gauge to clear a holding tank TPF tube, if clogged, then a reading to be taken.

What can I do if it is difficult to reach the tank?

The Tank Tender system offers maximum flexibility for installations. The installation instructions include tips that can help on tough installations, or you may consult the manufacturer for additional assistance.

How far away can the tank be from the unit?

Up to 1,000 feet, further if necessary. Each system comes with 30' of nylon tubing per tank, in a continuous roll.
