Weight of empty 6kg Calor Propane cylinder?

[Spriddler]

Trying to establish how much gas is in my part used 6kg propane cylinder, (red colour, steel) by weighing it.
The Calor website says an empty cylinder can weigh between 7.3 and 10.9kg. Such a wide weight variation of 3.6kg seems peculiar and doesn't help much.

The empty weight should be on the bottle, I think?

 

[Spriddler]

No, all there is on the bottle is a tin disc below the valve which has 'Test 20' and '17 00'. Nothing else at all.

 

[icantremember]

The Tare weight is printed on the aluminum plate around the bottle neck.

 

[Gellyneck]

Between 4.1 - 5.0kgs

The aluminium disc on neck of bottle has the tare weight in pounds and ounzes.

Yes lbs and ozs

 

[Spriddler]

Well that's thoroughly confusing.
Calor website: 7.3 to 10.9kg
Gellyneck: 4.1 to 5kg
SandraL: Lbs and Ozs on neck disc. Mine says '17 00' which if it means lbs converts to 7.7kg

 

[Cheshirecat57]

There you go
7.7 kgs

 

[Spriddler]

Hmm, I'll have to check it when empty.
Odd that the (same shape/dims/design) cylinders should have widely differing tare weights.
So according to the Calor website a full 6kg cylinder can weigh anywhere between 7.3+6kg and 10.9+6kg. So according to the bottle disc the empty cylinder weighs 17lbs although mine, when full must weigh 17lbs + 6kg
Bit of a muddle, innit?

 

[Podney]

Yes,their website is useless.
Surely it wouldn’t be too difficult for Calor to put a guard on the bottles?!
Maybe someone with an empty one will answer for us?

Just weighed my empty 6kg which has 19 00 on the label & guess what, it weighs 19lbs. So yours must be 17lbs.

 

[Gellyneck]

Apologies! I gave you the Calor Lite numbers.
I was comparing that against SafeFill yesterday.
On my way to the back of the class!

 

[Cheshirecat57]

FYI
A “small” Safefill weighs 3.5 kgs empty and 8.5kg when full
Costs £5.50 to fill
Was a no brainer to me

 

[Spriddler]

The reason I'm endeavouring to discover their contents is because I have two spare 6kg Calor Propane which have been in my shed since I fitted a Gaslow refillable system 2 years ago. I've no idea how full/empty they are and I plan to give them to my son use them up in his caravan.

 

[Cheshirecat57]

Ah,I see
Weighing is the “weigh” forward then
All the best

Why not use some bathroom scales?

 

[Spriddler]

Dup. Deleted.

And possible SCAM as well

Variation could be due to the amount of crud in the bottom
that would screw up any weight calculations up totally

 

[Podney]

Has anybody asked the manufacturer?

 

[Encantado]

I weighed my empty calor 6kg last year ,it was 8.3kg

 

[TonyEmm]

Yes lbs and ozs

That’s Calor being their usual helpful selves! Why pounds and ounces when they are sold in kilos? Folk much younger than me probably can’t convert it anyway!

Calor Sell the gas in kilos but the cylinder weight on the aluminium collar is in pounds and ounces. It’s not helpful when they don’t state the units! Worse, they show it as (in my case) 17.14 but it isn’t a decimal point so doesn’t mean that, it means 17lbs 14ounces.. . Remember there are 16ounces to 1 pound...
1 pound = 0.45359237 kgs.
1kg= 2.20462262 lbs.

The bottles are old

If it has up to 3kg (7lbs) of crud in the bottom I'd be surprised.
Also that's 3kg less gas.

Shouldn’t be when I’ve only had them 2 weeks and their next test date is shown as 20 35!

Nah, that's the way Calor show the weight when full .......20lbs 35gms.

 

[Wagoneer]

I've got a couple of 6kg Calor propane stored in the house garage (after changing to refillables). I must have weighed them full as there is a note attached which says 10kg FULL.

Interestingly, the aluminium plate says 9 12 (which I assume is 9lb 12oz) on both bottles which converts to 4.42kg. So....I've been short-changed by 0.42kg of gas

Furthermore, the base ring shows info in metric, 14.5 litres gas and tare weight of 4.42kg (which comfirms the 9 12 marking).
