Well, for what I have known, no digital scale is truly accurate, at least to an extent. Look, there are many factors that determines what a tank will weigh. And for 50kg gas cylinders, it seems like the older version is even more heavier than the recent version. This is because, the scale weight of a gas cylinder doesn't actually mean that's what it can contain. That is where LPG worth (LW) comes to play. LPG worth means the actual liquid that should or can be filled in that particular gas cylinder. You can check out all these technical details on the bottom ring side of every 50kg gas cylinders.

Also, there is the net weight, gross weight or tare weight - this is the weight of an empty gas cylinder. This is can also be the total weight of the gas cylinder, including the handle top and the bottom ring. A 50kg gas cylinder is not actually 50kg.

So here is the thing, take away the handle top and the bottom ring, what you will have is the LPG worth (LW). This is why I always recommend the Calor 50kg gas cylinder, which can contain 100.2 litres of LPG. Convert that back to kg, then you will escape the cut-off valve. Every 50kg gas cylinder comes with cut-off valve, which helps prevent overfilling. I don't know how the technology was installed, but what I know is that the cut-off valve has a 88% percentage refill point. Once you are getting to that point, it will just cut-off the refill. You won't know, neither will the gas refilling operator. The remaining will become pressure or vapour, so to help for more space inside the gas cylinder. Yes, I know some 50kg can contain more than 50kg, even goes as containing 60kg

What you don't know is that, the conversion of liquid back to gasous state happens at the top of every gas cylinders.

What if overfilling causes cooking gas shortage?


So, just save your money. Instead of saying that you want to refill 50kg, tell the operator that, I would like to refill 45kg or 40kg.

Remember, knowledge is power.

Nice peace OP..
Does same apply to filling 12.5kg cylinders.....
Filling 11.5 or 12kg to beat the cut off value?

Not applicable. Although you can 100 percent trust these gasman. Mostly they underrefill. Anytime you refill, just ask to scale, so to confirm
