How to Tell if a CO2 Tank is Empty

CO2 tanks are usually made of opaque materials. This makes it hard to determine the amount of gas left. A double gauge regulator is used in most tanks. A gauge measures the amount of CO2 left in your cylinder and provides results on a calibrated scale. Without a gauge, you will need to estimate the amount of gas left. This poses a risk of running out of gas during the game. It is recommended to observe the readings regularly to pin point the refill date. Another effective way of keeping track of your CO2 tank is weighing the tank at different instances. This discussion provides different ways of knowing when the CO2 tank is empty.

Pressure Gauge
The high-pressure gauge starts dropping when the level of CO2 drops. Some regulators come with dual gauges which help in giving an idea of how much is left in the tank. One of the gauge shows the air pressure and the other shows amount of air left in the tank. Some regulators have one pressure gauge. All the gauges will read zero when the tank is empty.

Weighing
Weigh your tank when its empty and note down the weight. After that, refill the tank and keep track of the amount of gas by weighing it at different instances. Develop a culture of noting down the weight after every game. This will make sure that you won’t run out of gas while in battle. This method also works best when you don’t swap tanks. Using one tank for refill will reduce the number of measurements.

Estimated Values
There are values provided by frequent players which might give you a rough figure. A 5-pound tank used 24 hours a day is expected to last for six months. Therefore, a 10-pound tank will last for a year. A tank being used 8 hours a day is expected to last four months and 15 days. This can be combined with the drop rate on the pressure gauge to monitor the amount of CO2 in your tank.

Estimate Tricks
There are some tricks which will give you a rough idea of the amount of gas in the cylinder. Open the valve slightly as you listen to the gushing air. Observe any white foam coming out. When a tank is empty, no white substances will be seen coming out. A tank with liquid produces a white foam with a gushing sound. When there is little foam or only air, the tank is getting depleted or empty. You can use a tack hammer to hit the tank (be very careful doing this). The sound produced will give you a rough estimate of the amount of gas left.

In conclusion, a pressure gauge is the best way of monitoring the level of CO2 in your tank. It is recommended to keep a spare just in case. Remember to account for in the lines during refills and air lost when bleeding the tank. A gauge is the best way to keep track of CO2 in your tank. You can opt to weigh your tank using a bathroom scale and keep records. This is more useful when using bulk tanks since they tend to have constant pressure even when gas is being used up. The estimated values and tricks like observing the foam and sound are also helpful.
