NF EN ISO 7278-1
Liquid hydrocarbons. Dynamic measurement. Proving systems for volumetric meters. Part 1 : general principles.
The purpose of proving a meter is to determine its relative error or its meter factor as a function of flow rate and other parameters such as temperature, pressure and viscosity. The following types of proving systems are in use: tank prover systems; pipe provers, bidirectional and unidirectional; master meters. They can be used either connected (fixed or mobile) to the metering station or in a central proving station.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
