Range of services provided:
- Verification of measuring system indications by the Management Centre of PERN S.A.
- Validation of measurement system indications as part of external metrological check carried out by local measurement administration units and notified bodies in cooperation with the Measurement Centre of PERN S.A.
Type of objects:
Validation of the indications provided by the measuring systems conducted by the Measurement Centre of PERN S.A.
- Measuring systems in pipelines for continuous and dynamic measurement of the amount of liquids other than water, excluding cryogenic liquids, with a volume stream of not more than 12 000 dm3/min.
- Measurement systems for filling and emptying ships, railway and road tankers with liquids, excluding liquefied propane-butane gas and cryogenic liquids, with a volume flow not more than 12 000 dm3/min.
Accuracy check reports on the measurement systems as a part of their calibration and to check the accuracy of measurement system indications as a part of external metrological control carried out by local measurement units and notified bodies in cooperation with the Measurement Centre of PERN S.A.
- Measuring systems in pipelines for continuous and dynamic measurement of the amount of liquids other than water, excluding cryogenic liquids, with a volume stream of not more than 6 000 dm3/min.
- Measurement systems for filling and emptying ships, railway and road tankers with liquids, excluding liquefied propane-butane gas and cryogenic liquids, with a volume flow not more than 6 000 dm3/min.
Products checked:
Systems for measuring the amount of crude oil, diesel, petrol, aviation fuel, heating oils and other products with the following properties may be checked:
- density: from 300 kg/m3 to 1300 kg/m3,
