The 9225 Lil’ Devil II™ is an enhanced version of our popular Lil’ Devil™ tank monitor, offering a low-cost solution for indoor, multi-tank monitoring of non-volatile fluids. Ideal for water or oil tanks, this system provides remote monitoring for up to 5 tanks via cellular communications with 4G/LTE Cat M1 technology.
Ideal for use with indoor, non-pressurized, vented bulk tanks containing various fluids, including motor oil, lubricants, water, antifreeze, concrete additives, and more. The Lil’ Devil II is a bubbler system that measures fluid levels by pumping a small amount of air through a tube, calculating pressure, and determining fluid depth. It installs quickly, is a low-cost option for monitoring up to 5 tanks, and is especially popular where instrument-clogging is common.
Note: It is not suitable for environments where slight water-condensate contamination may pose an issue. The Lil’ Devil II is designed for easy installation and is compatible with Level Devil® software for accurate fluid volume calculations.
