Zero Verification & Restamping
ZERO VERIFICATION
METCORE is an independent company providing independent party field zero verification of mass flow meters and associated systems. We are appointed by Enterprise Singapore as an Authorised Verifier under the Weights & Measures Programme.
Over time, the observed zero offset can be affected by flow sensor condition, pipeline stress, internal coating build up, etc. The American Petroleum Institute (API) recommends periodic verification of the stored zero value. This is necessary to ensure that the observed zero offset value is within prescribed limit as defined by one or more of the following conditions:
-
Manufacturer’s recommendation.
-
Performance testing and monitoring.
-
Custody transfer agreements.
METCORE is accredited by Lloyd's Register (LR) to provide zero verification of mass flow metering systems onboard LR's bunker tankers.
Periodic Maintenance
RESTAMPING
Periodic Maintenance
As required by ESG, flowmeter used for custody transfer has to be verified by an AV for its accuracy, and thereafter stamped with the W&M verification seals and affixed with Accuracy Label under the W&M Programme. Accuracy Label has a validity of 12 months. The Accuracy Label will be renewed after the flowmeter has been re-verified for its accuracy to ESG’s prescribed maximum permissible error or MPE. With the AV status, Metcore is able to provide a one-stop solution to verify the MFMs and renew the Accuracy Label.
