Custody Transfer Systems
Examples for custody transfer installations:
Maintenance work on a Crude oil transfer installation in the South China Sea:
2 duty meters and one master meter on crude oil after the separator. The duty meter get periodically calibrated by the master meter. The master meter gets recalibrated yearly on a onshore calibration rig. The key issue for a reliable operation here is consideration of the saline environment - the istruments are installed on a platform and there in the open only a few meter above the open sea level.
Custody transfer of Diesel fuel at a refinery in Pakistan: 2 duty meters which are frequently calibrated by a mobile piston prover skid
