Volume Control of Bottled Drinks
Hi all,
Needing some help!! I am dealing with bottled drinks for the first time and wondering about volume control. I have found the weight volume control all a bit complicated to get my head around! I would have presumed I would be emptying the contents of a bottle into a jug for example to measure how much was actually in it but now I am reading about weighing the lot? Would greatly appreciate any advice or pointed in the right direction on where I can get it.
Thanks!
Before you start weighting anything, you will need to know what it's specific gravity is!
1 litre of product, isn't necessarily 1 kg (unless your water at 20C)
if your liquid has a specific gravity of 0.988, then 1 litre would weight 988g
this is your starting point!

Well...
It's hard to give direct explination to you without knowing where in the world you are located. For example in the United States you can weigh everything and allow a small amount of under packed product if you can prove the average of the lot was over though you can sill be in trouble due to severly underpacked items.
That's typically how I've seen weights performed at my last two locations. There was a minimum weight and a maximum weight and a checkweigher kicked anything off that was too low. With a checkweigher you can set the weight of the total product with packaging and it will reject anything that is too low. Meanwhile your operators would tare out the packaging on a scale and then weigh the product and with the packaging tore out of the total weight you will know how much is in your product.
For example. If you are shooting for a 500g (+10g - 7g) product you put the packaging on the scale and hit tare. Now let's suppose the scale says -80g once the packaging is removed. When you put a product sample from the line on it anything that is 493 - 510g would be acceptable.
However dependent on location there may be different laws on how much under you may be allowed if at all.
Ohh now I took the question to "how do I validate that I have the correct amount in the first instance", and not about the weights of the whole batch!
As Mr I says, need to know where you are, so that someone can quote you the correct legislation.

Yeah sorry it could have been interpreted as both really.........I am based in Ireland. Yeah I deal with the weighing of dry product T1/T2s etc at the minute but the volume side of things has thrown me a bit! :/ ............
Thanks!

Do you know the specific gravity of the product you are packing?
Hi Caz,
Apologies for the delay in response. The specific gravity is 1003
Thanks

Specific gravity is 1003 ??
or 1.003
What type of drink product is going into these bottles?? British Beer??
Yes 1.003. It is a fermented drink but no not a British Beer :)
