For in-situ verification of flow meters in the field, Energoflow AG offers a range of transferable standards sets. These sets comprise of pre-calibrated flow meters, flow conditioners, and straight runs in an easily transportable case. They can be used for proving flow meters by comparison method in the field without de-mounting.
Transferable Flow Metering Standards Set or Portable standard (standard of comparison, the transported standards) is a secondary standard designed for comparisons of standards and verification of measuring instruments.
Portable standard (PS)- high precision measuring instruments (MI) is used to transmit units of physical quantities on the primary standards to MI being certified (under test), with the capability to transport them directly to the place of installation of MI for verification (certification).
The table below shows the main characteristics of the standard meter of the Hygienic Master FEH521, used in the Portable standard unit of liquid flow.
