Beer flow monitoring equipment from Brulines does not require a Weights and Measures stamp.
That's the finding of Trading Standards and Local Government co-ordinator LACORS.
The two groups concluded that Brulines is not covered under section 11 of the Weights and Measures Act, which means it does not require official accreditation.
A Brulines statement said: "Following their recent investigation into Brulines, Trading Standards and LACORS have concluded that Brulines' equipment is not currently prescribed under section 11 of the Weights and Measures Act 1985 thus is not required to be passed as fit for use in trade.
"This confirmation of the status of Brulines' licensed premise flow monitoring equipment follows a comprehensive assessment by Trading Standards and LACORS of the equipment and methodologies employed by Brulines to help manage tie compliance, and effectively means that under the Weights and Measures Act of 1985 Brulines is not required to have any item of equipment used in this process 'stamped'."
Brulines said it was not taking any further questions on the matter.
