Low-Cost, Indoor, Multi-Tank, Local-and-Remote Tank Monitor
The 9225 Lil’ Devil II™ is the greatly-improved new version of our popular Lil’ Devil™ tank monitor (long a popular industry leader in low-cost tank monitoring).
The Lil’ Devil II™ measures and monitors many different non-volatile fluids in vented tanks, and is especially popular as a water or oil tank monitor.
With our original cellular communications remote-monitoring and alerting features, this new system adds a digital display on the unit, and serves more tanks, plus other improvements.
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.
NEW: The Lil’ Devil II now uses 4G/LTE Cat M1 cellular communications — which covers the United States, and most of the cellular telecom world — extending its useful life well into the next decade!
● 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.
Use with indoor, non-pressurized, vented bulk tanks, containing:
- Motor Oil & other Lubricants
- Concrete Additives
- Paper recycling pulp mix
- & many other fluids.
- Ideal for many fluids where instrument-clogging is a common problem.
- Not for use where slight water-condensate contamination causes a problem. (some condensate may be induced by instrument, especially during high humidity)
- Installs quickly and easily
- Low-cost option for monitoring up to 5 tanks
(for more tanks, just add additional units)
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. 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.
