For as little as $150 per tank, this low-cost solution has a powerhouse of features, including:

Remote tank-level information at your PC,
for up to 5 tanks, via cellular* telecommunications.

Live data on the digital display panel for local readings.

Alerts (set to your specification) when a fluid level gets too low, or too high — for better product management.

Alert e-mails sent to you when fluids need to be filled or emptied.

HOW IT WORKS:

The Lil’ Devil II tank monitor is designed to be installed quickly and easily — for use with non-pressurized bulk tanks containing motor oil, lubes, water, antifreeze and many other fluids.

Bubbler system includes pump and sensor above tank, and tube to bottom of tank.
Especially popular as a water or oil tank monitor, Lil’Devil II™ actually measures many different fluids in vented tanks.

Lil’ Devil II is a “bubbler” system:

When prompted, the monitoring unit pumps a tiny amount of air through a tube to the tank, and measures the pressure required to force air bubbles out through the open end of the tube, at the bottom of the tank.  The amount of air pressure needed to pump the bubbles varies with the weight (and volume) of the fluid.

The pressure information is used to automatically calculate the vertical height (depth) of the fluid in the tank.  Then, using the tank size and geometry information stored in the system’s database, Level Devil® software calculates the actual gallons remaining in the tank and provides a digital read of the level — either on the tank monitor local display, or in a secure, password-protected online web page (accessible from your computer, tablet or smartphone).
