Introduction

This specification is based on JJG1038 "Coriolis mass flowmeter verification procedures", GB/T 31130 "Coriolis Flow meter "for the technical basis, combined with China's Coriolis mass flow meter industry status, the JJG1038- 2008 Revision Appendix A "Type Evaluation Outline" for revision, applicable to the Coriolis Mass Flow Meter Type evaluation work. This specification is prepared according to JJF 1016-2014 "Guidelines for the preparation of the Outline of Measuring Instruments". This specification compares with the JJG1038-2008 Appendix A "Type Evaluation Outline", the main technical changes are as follows. --- in accordance with the JJF 1016 format for the preparation; --- increase the flow meter to modify the parameters of the protection function; - increased electrical safety test; --- clear flow meter in the absence of packaging conditions for transport storage test; --- increase the flow meter after the transport and storage test metering performance requirements; --- The determination of the result of the type evaluation has been modified. The previous version of this specification is released as follows. JJG1038-2008 "Coriolis Mass Flowmeter" Appendix A "Type Evaluation Outline". Coriolis mass flowmeter type evaluation outline
