GB/T 17289-2009Liquid hydrocarbons -- Volumetric measurement by turbine meter systems (English PDF)

Foreword

This standard is equivalent to using ISO 2715. 1981 "liquid hydrocarbon volumetric turbine meter systems." this standard is equivalent translation ISO 2715. 1981.

This standard of ISO 2715. 1981 made the following editorial changes.

--- Remove the ISO international standards foreword;

--- The "this International Standard" be replaced by "of this standard." this standard replacement GB/T 17289-1998 "liquid hydrocarbon volumetric turbine meter systems." this standard 17289-1998 major changes compared to GB/T as follows.

--- The full text of the ISO 6551. 1982 to GB/T 17746-1999;

--- The full text of the GB/T 17288-1998 amended as GB/T 17287-1998;

--- Introduction delete the discussion of positive displacement flowmeter.

Appendix A of this standard is a normative appendix, Appendix B is an informative annex.

The standard proposed by China National Petroleum Corporation.

This standard by the National Standardization Technical Committee of Oil and Gas.

Introduction

Turbine Flowmeter mainly by detecting passage of the fluid average velocity of the rotor constituted. The kinetic energy of the impact surface of the fluid with a radial guide Rotor angle side ribs and partially decomposed into a tangential kinetic energy of the rotor is rotated, the rotation of the rotor is proportional to the flow rate. By mechanical rotation of the rotor, ,, Magnetic or electronic means of optical detection, and recorded in the readout meter. This test must be recorded with a known volume Volume for comparison.

To guide the design of turbine flowmeter liquid hydrocarbons metering devices, installation, operation and maintenance, development of this standard. Appendix A gives the turbine flow Detailing and characteristics of meter components. Appendix B provides troubleshooting guide.

GB/T 17289-2009/ISO 2715. 1981 Liquid hydrocarbon volume measurement by turbine meter systems

1 Scope

This standard is based on the nature and characteristics of the measured liquid turbine flowmeter, turbine flowmeter selection provides system design, installation, operation Maintenance and general rules.

This standard applies to the petroleum industry, in different contexts, using a variety of turbine flow meters for different types of liquid hydrocarbon flow measurement.

This standard does not apply to the measurement of two-phase fluid.
