What is ISO 7278-1 - Proving systems for volumetric meters about?
ISO 7278-1 provides general principles for proving systems for meters used in dynamic measurement of liquid hydrocarbons.
The following types of proving systems are in use:
Tank prover systems
Pipe provers, bidirectional and unidirectional. Pipe provers with precision tubes as described in 6.7 are available for special applications
Master meters. Indirect procedure of volume comparison which causes additional uncertainties can be used for all liquids and flow rates, provided that the master meter is proved against acceptable proving systems under conditions which simulate those under which it will operate.
