How do I read my Propane Tank Gauge?

Here's a simple "how-to" guide for the next time you check your tank gauge. Knowing how to read your propane tank gauge will help accurately relay the information to one of our Customer Care Representatives on the other end when you call us for a delivery.

You may have heard before that the gauge shows the total amount of gallons in the tank. Incorrect! It actually displays the propane level as a percentage of the capacity of your tank. So what do you need to know about checking your propane tank levels?

Not every propane tank has the same gauge. But they all have the same purpose, to show you how much propane is in your tank. Most tank gauges are “float gauges” (much like a fuel gauge in a vehicle – think antique trucks!), which reads the level of liquid propane in the tank by the floating arm. This does so by a float assembly that is within the tank and controls the arm gauge. While the level drops, the float gauge will also. Below are some example gauges you may come across.

Propane tank gauges vary in style. So how do I check my propane tank levels?

Using example B as our spotlight propane tank gauge, notice how the floating arm is at 40%. Using that 40%, we can determine how much propane is left in your tank based on your tank size and propane tank gauge reading we’ve just done.

To make life simpler and spare you from doing the math, we’ve put together a handy chart that is a great quick glance at how many gallons you have left in your propane tank.
