How To Read Your Propane Gauge.

Reading your propane gas gauge is very simple to do. The gauge is located under the dome at the top of the tank.

The numbers on the gauge represent a percentage. The pointer in the middle of the gauge points to one of those numbers. Your propane tank is considered to be full at 80%, this allows for the expansion of the propane vapor.
Here is an easy formula to figure out how many gallons of propane you have left in your tank:
Tank Size X Percentage (gauge reading) = Gallons
Example: A 120-gallon tank that the gauge reads 60% would be 120 X .60 = 72 gallons.

GAUGE READING	REMAINING GALLONS
	120-Gallon Tank	250-Gallon Tank	500-Gallon Tank	1000-Gallon Tank
80%	96	200	400	800
70%	84	175	350	700
60%	72	150	300	600
50%	60	125	250	500
40%	48	100	200	400
*30%	36	75	150	300
*20%	24	50	100	200
*10%	12	25	50	100

*--Holtzman Propane recommends that you call them when your gauge reads 30% so that there is ample amount of fuel for you to use before they arrive
