Specifications for the Approval, Installation, Use, and Verification of Flow Conditioners used in Gas Measurement Systems (S-G-04)
This information bulletin is intended to advise natural gas sector stakeholders that Measurement Canada (MC) has now issued Specification S-G-04. This specification has been developed to communicate, within one single document, generic requirements for the approval, installation and inspection of any approved make or model of flow conditioner used in gas measurement systems.
Historically, provisional specifications had been developed and published for each individual make or model series of flow conditioner. The review of these documents, performed under the Government of Canada's paper burden reduction initiative, resulted in a decision to consolidate the applicable requirements into one common specification in order to eliminate duplication and prevent confusion by providing a uniform set of requirements applicable to all flow conditioners. As such, provisional specifications PS-G-01, PS-G-05, PS-G-10, PS-G-11 and PS-G-12 have now been revoked.
MC is in the process of creating new notices of approval for the models of flow conditioners previously covered under these former provisional specifications. New requirements identified in S-G-04 — Specifications for Approval, Installation, Use and Verification of Flow Conditioners Used in Gas Measurement Systems which were not specified in these former provisional specifications, do not apply to flow conditioners manufactured prior to the issuance of the applicable notices of approval.
