Liquid fuel measuring systems
When you use a measuring system designed for the distribution of liquid fuel to determine the price, the system must meet the requirements set for its structure and performance. These requirements apply to the whole measuring system.
After commissioning, the reliability of the liquid fuel measuring system is monitored by verifying the liquid fuel meters periodically. A measuring system comprises the meter itself and all devices required to ensure correct measurement or facilitate the measuring operations.
A fuel dispenser is a measuring system intended for the refuelling of motor vehicles, small boats and small aircrafts.
A self-service arrangement allows customers to use a measuring system to obtain liquid fuel for their own use.
A self-service device is a specific device that is part of a self-service arrangement and allows the measuring system to operate in the self-service arrangement in question.
A declaration of conformity is a written statement by the manufacturer declaring that the measuring instrument is compliant with the requirements set out in the Measuring Instruments Directive.
Verification of a measuring instrument means assessing the conformity of the measuring instrument in a verifiable manner. After commissioning, verification must be carried out every 2 years on liquid fuel measuring instruments that are in use. This ensures that the measuring instrument functions reliably during operation.
Other definitions on the subject can be found in the legislation.
In addition to the Measuring Instruments Act 707/2011, requirements on the manufacturing, placing on the market and commissioning of liquid fuel measuring systems can be found in the decree 1432/2016, whose requirements comply with the requirements of the Measuring Instruments Directive 2014/32/EU. The essential requirements on liquid fuel measuring systems have been set out in Annex MI-005 and other essential requirements in Annex I.
