Flow meters and volume standards (tanks/containers) used for financial settlement must undergo conformity assessment. Typical meters include fuel dispensers, meters on tank lorries and filling stations for tank lorries, meters in the chemical industry such as large petroleum meters, milk meters, beer meters, etc. The Norwegian Metrology Service supervises these meters. During supervision, the Service will normally check the accuracy of the meters and assess this against the tolerances set out in the regulations.
To ensure that the meter functions satisfactorily under normal operation, it is tested when installed at the place of use and with the same medium as under normal operation. It is therefore important that provision is made for inspection of the meter during installation. The error limit at inspection is, for most meters, less than or equal to ± 0.5%. The repeatability requirement is less than or equal to 0.2%.
The Norwegian Metrology Service’s volume lorry inspects tank filling facilities efficiently and without inconvenience to the user.
A litre is a permitted unit and corresponds to 1 cubic decimetre. Volume is derived from length, but when it comes to liquid measurement, traceability is ensured by weighing the liquid and converting it to volume using temperature-corrected density.
The Norwegian Metrology Service offers on-request verification as one of our services. As a neutral third party, we can carry out verification and in-use inspections and issue documentation. We have the equipment and expertise to help your enterprise meet the requirements for measurements.
We verify that the measurement corresponds with the actual flow and that the meter is approved for its intended use.
