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.
