GB/Z 33875-2017Guidelines for the use of GB/T 2624-2006 (English PDF)

1 Scope

This Guidance Document gives guidance on the use of GB/T 2624-2006 (all parts). GB/T 2624-2006 is a circle

The pressure drop caused by the contraction in the shape pipe is based on the national standard for measuring the flow (see 5.1 of GB/T 2624.1-2006). It is based on traffic measurement

The amount of theory and experimental work carried out a series of rules and requirements.

The details of the range see GB/T 2624.1-2006 Chapter 1. This document applies to the definition and symbols see GB/T 2624.1-

2006 Chapter 3, Chapter 4.

GB/T 2624.1-2006 and this document do not discuss the theoretical background details, the content can refer to other related to the fluid flow of teaching

Book.

According to the provisions and requirements of GB/T 2624.1-2006, the uncertainty of the flow measurement can be achieved to about 1% of the calculated value of the flow.

Before selecting the most suitable type of differential pressure device for a particular application, consider each of the types given in GB/T 2624-2006 (Parts 2 to 4)

Limit the use of a device. Parts 2 to 4 also serve as a basis for preliminary design of the metrology system.

GB/T 2624-2006 (parts 2 to 4) gives the detailed design, manufacture and final inspection necessary information.

GB/T 2624.1-2006 does not include secondary devices, but Chapter 6 of this document made a normative reference to ISO 2186.
