Why Tank Monitors?

In the old days, the game was simpler. Now winters swing from record cold one year to record warm the next. 15% of fuel customers have secondary heat sources. The K-factors just can’t keep up and that doesn’t even take into consideration propane accounts that are not on a heat curve.

As gallons per customer shrink, and good drivers are harder to find, your deliveries need to be as streamlined and flexible as possible. Industry experts agree that each delivery costs between $50 and $75 per stop. Filling tanks at truly optimum levels, reducing deliveries, and eliminating runouts, is a mission critical for today’s propane and oil companies.


Make your customers feel 100% confident.

Only 39% of propane and oil customers believe their company will never let them run out of fuel.* With Gremlins, customers will know you aren’t just guessing. They will have a smartphone app that shows them how much fuel is in their tank and when they will get their next delivery.
