Milk collection wrong !!

[JFK’s brain]

100% sure lorries are incorrectly reading milk when collecting from bulk tank by a certain danish company

Anyone else noticed this happening ?

 

[Kiss]

Hate it when milk recording doesn’t tally with the tanker

Is it under or over reading? There does seem to be a variation ( relatively small) between tankers, but we did have issues with tankers/ certain drivers picking milk up here, as first collection after CIP’ing and still having water in pipes. We would get 60-70ltrs per collection but FPD’s would be all out.

Mostly under reading but very occasionally one that over reads. Was a good 2 inches more in a 3000 litre bulk tank yet was only up 4 litres from previous day.
Not really sure how to approach this. Noticed it happening a year ago and when confronting them they just said that all lorries are weighed on return and they would look into it. Never heard anymore
Also when one lorry was reading so low (approximately 600 l) had to ring them up about it otherwise not sure would have got paid if we hadn’t called them

Should say it does just seem to be a certain couple of lorries reading low but does seem to be a bit of variation lorry to lorry. Obviously doesn’t matter a few litres either way but appears more to me

Could an in-line flo-meter be installed. ??

 

[serf]

As above it needs some meter 'in your face ' that's calibrated and signed off by trading standards or some form of authority and see where things go from there , or could weight bars go under the legs of bulk tank
.

Don't know how it works there but the meters have to be checked and calibrated here. I'd ask your buyer to show proof of calibration (it should be on the tanker) If I remember correctly the meter has to be calibrated with milk not water.
Are you sure the driver is doing everything properly and not chucking the last bit down the drain?

Years ago we had a square tank with ice jacket on, on the side imprint into the stainless steal there was a measuring gride( like looking at side of measuring jug) it's was amazing how much different tankers varied, great little tank, never any bother, had to manually wash out after collection.

Sounds like we’ve got your tank Martyn. Exactly that, can see if the milks up or down and often doesn’t seem to correlate with the tankers. They do seem varied as you say

Pretty sure it’s not the drivers can’t see how it could be mate

and of course the first place to go is 5 messages on a public forum… 2 inch

Just checking that they are sucking the tank completely and not pulling the hose off and letting some down the drain? Are you there when they pick up?
I'd get on to your buyer and ask about how they calibrate the meters, perhaps mention you'll check with the authorities.

Not the company I supply now but I once went out to work one morning to see milk all over the yard. We checked everything and couldn’t work out where it came from, so decided it was the tanker. The tank actually split and the driver and the guys on intake didn’t notice. They had to check the weigh tickets to be sure the problem was theirs

We regularly fill the tank to over flowing and the variance can be up to 250 litres. Should be 10600 full goes down from there.

2.3% error max which is within range the meters are probably plated for.

Some dairies have a weighbridge and that is the only way to be 100% sure.

 

[Milkcow365]

I have a weight bridge might put a few loads over it would help calibrate my meters as there in kg to

Had a milk tanker that didn’t have a flow meter but it had weigh cells,my yard is on a slope so I regular got a false reading,one day the tanker was full and it was pumping milk straight out the overflow down the yard,this meant the weight was being measured like it would with a flow meter.
It turns out the tanker was a one off and they kept swapping it around the different runs,I can’t blame Arla because it was an outside haulier.
My parlour totals every milking so I know daily what the measurements should be,same tanker virtually every day here so not far off.
A local large herd runs the artic over the weigh bridge rather than a flow meter purely for speed and ease.

Wouldn't bet on it- the tankers probably pick up 50 kg of dirt on their round. The amount of crap that can be washed off a truck that goes on farms has to be seen to be believed.

The more I read on here about your milk collection, the more I think its cowboy central. All the hoops they make farmers jump through and they can't even run a decent collection service.
