Below, fine outline four methods the will help you examine your propane tank level. 

How to inspect the level that a propane tank

1. The warm water, cool hand method

This is the quickest and also easiest method to gain a feel for the propane level in your tank. Merely pour heat water over her tank, and then operation your hand follow me the side of the tank.

As you reach the level that propane in her tank, the temperature will rotate cool to the touch. This method relies ~ above a physics reaction in between the warm water top top the tank surface and the propane inside your tank - developing a temperature difference you have the right to feel. Together the hot water heats the tank’s exterior, the propane reacts, creating a cool spot at the fill level. This method won’t offer you a specific reading, however it will allow you to estimate just how close you are to needing a tank exchange. 

2. Using a gauge

This simple solution gives users one instant-read on measure up the level of their portable liquid propane gas tanks. Many portable LPG cylinders equipped v gauges refer the volume that propane in state of portion of complete - showing 100 percent as soon as the tank is complete with 20 pounds the propane, climate dropping during use. 

Such gauges work from push inside the tank, and also make a determination of continuing to be levels. This style of pressure reading gauge have the right to be uncovered in house repair and also retail outlets transparent the country. They space inexpensive, basic to install, and easy to read. Once yours is in place, you’ll just remove it once the tank is depleted and also install it on your following one. 

3. For an ext Precision: Tipping the scale Method

This an approach offers a much more precise measurement, however it calls for some effort to disconnect your propane tank indigenous the grill. You’ll additionally need a family scale and also the patience to carry out a few simple calculations. 

Propane tanks typically are stamped with an north or “tare” weight - usually in between 17 and 19 pounds. A typical sized propane tank when filled hold 20 pounds that propane. Location the tank top top your scale to obtain the total weight, and then subtract “tare” load to determine how many pounds of propane is left in her tank. 

Pounds that propane staying = - <“tare” weight: 17-19 lbs> 

The formula can be carried out additional to recognize the variety of gallons, and beyond, to calculation the lot of cooking time left in her tank. Take her net weight divided by 4.2 to convert the analysis to gallons.

Gallons the propane = tank weight in lbs. / 4.2 

A gallon the propane contains approximately 92,000 BTUs, and also a reading of her grills BTU every hour rating deserve to offer a stormy estimate of cooking time left in her tank. 


4. The Mathematician Method: exactly how Much cooking Time carry out You have Left

Get the end your calculator, since this facility method of determining just how much propane is in your tank needs several actions through the world of math formulas. Yet it is just one of the most accurate viewpoints to estimating your propane levels - and also can be provided in a predictive manner together you deplete your tank. 

Remember this figures: A full tank consists of 20 pounds the propane, the weight of propane divided by 4.2 counter the units into gallons, and a gallon of propane produces around 92,000 BTUs the energy. To complete the formula you’ll require to know the BTU every hour rating of her grill, and you’ll need to variable in the heat setup you setup to use while grilling. 

For example, to recognize the minimum lot of cooking time you can expect you’ll be able to cook with a complete tank, you have the right to use the formula: 


cooking Time = _______________________

Max BTU per hour of grill 

In this case, your propane tank has 4.76 gallons that propane capable of delivering about 438,000 BTUs. If her grill is rated for 30,000 BTU every hour on the high setting (438,000/30,000) you deserve to expect in between 14 and also 15 hrs of food preparation time ~ above the highest possible setting. 

How to adjust for different cooking temperatures

To do adjustments for cooking temperature, you’ll have to incorporate something known as the “K” factor, i beg your pardon assigns a numerical value to food preparation temperature. Because that instance, just using 3 burners top top a 4 burner unit, top top a tool setting, is assigned a K element of .56. Alter the previous formula to account for the K aspect would appear as this: 


food preparation Time = _______________________

(.56 x 30,000) 

This way at the lower usage, you might expect about 26 hours of food preparation time. 

While rather complicated, this formula have the right to be a funny exercise, and also with part tweaking could help you predict no just exactly how much cooking time you’ll have, but how much propane you’ve used with each outing. 


How carry out you recognize if her propane tank is expired?
