2.1. Weighing the Tank

Weighing your propane tank is one of the most accurate methods for determining the remaining propane. This method involves using a scale to measure the tank’s weight and comparing it to the tare weight (TW) stamped on the tank.

How to Do It:
1. Locate the Tare Weight: Find the tare weight (TW) stamped on the collar or handle of the propane tank. This is the weight of the tank when empty.
2. Weigh the Tank: Use a bathroom scale to weigh the tank.
3. Calculate Remaining Propane: Subtract the tare weight from the total weight. The difference is the weight of the propane remaining.
Example:
- Total Weight of Tank: 37 pounds
- Tare Weight (TW): 17 pounds
- Weight of Propane: 37 – 17 = 20 pounds
- Since a gallon of propane weighs approximately 4.2 pounds, you have about 4.76 gallons of propane left (20 / 4.2 ≈ 4.76).

This method provides a reliable estimate, allowing you to plan your refills accordingly.

2.2. The Hot Water Method

The hot water method is a simple and effective way to gauge the propane level without any special tools. It relies on the temperature difference between the propane and the empty space in the tank.

How to Do It:
1. Pour Hot Water: Pour hot water down the side of the tank.
2. Feel the Tank: Carefully feel the tank from top to bottom.
3. Identify the Level: The point where the tank feels cool to the touch indicates the propane level. The area above this point will feel warmer.
Explanation: Propane absorbs heat, so the metal will feel cooler where the propane is present. The temperature difference provides a clear indication of the propane level.

This method is quick and easy, making it a convenient option for regular checks.

2.3. Using Propane Tank Gauges

Propane tank gauges offer a convenient and direct way to monitor your propane levels. These gauges attach to the tank and provide a visual reading of the propane level.
