Foreword

This revised standard adopts ISO 15169.2003 "Petroleum and liquid petroleum products using a hybrid tank measurement system vertical cylinder The volume of liquid in the tank shape, the method "density and quality. This standard is based on ISO 15169.2003 redrafted the standard clauses structure with international standards. In the use of ISO 15169.2003, the standard of the present situation of China the following technical corrections. --- In view of the tank wall temperature using GB/T 19779 algorithm, thus increasing the GB/T 19779 "Petroleum and liquid petroleum products, fuel gauge Operators static measurement "as normative references; --- Because the field component calibration using the inconvenience, so the inherent accuracy of the system table 3 automatic tank custody transfer measurement of volume-based thermometer Replaced by a system calibration inherent accuracy; --- For the 6.2 paragraph 4 "If HTMS is mainly used for mass or density measurements.", Removing "or density" The reason is to reduce the density measurement ALG accuracy will result greater impact; --- To avoid misunderstanding, "1) For zero adjustments, disconnect the transmitter to the atmosphere in the pressure port 8.5.2.1. "To" 1) For zero adjustments, disconnect the pressure transmitter is connected with the tank line and make it the impulse towards big mouth gas. "; --- Suitable for our habits, supplemented by oil meter standard-density (Dref) and volume correction factor in Table 5 (VCF) content; --- Table 6 formula Dobs = Dref/VCF there is an error, it should be replaced Dobs = Dref × VCF; --- Suitable for our habits, added in Table 6 to determine the volume correction factor (VCF) with oil content meter. This standard also made the following editorial changes. --- 5.2.1 Pressure Sensor will involve the naming convention Description Note into 5.3.1; --- Finally, the increase in the 6.3 "Note. The maximum error of the pressure sensor should contain additional temperature error."; --- The data in Appendix A metered volume of gross A.2 formula for calculating the amount of the adjustment of the floating roof (FRA) to discharge liquid floating roof Product (FRV), while additional calculations floating roof drainage volume formulas; --- Informative revised Table B.3 in Appendix B, Table B.4, B.5 and B.6 of the table part of the calculation data; --- Will B.2 Informative Appendix B in the B value formula "UP1-zero" to "UP3-zero".

1 Scope

This standard gives the hybrid tank measurement systems (HTMS) the selection, installation, commissioning, calibration and inspection guidelines, through the system can Liquid petroleum and petroleum products storage tank to measure the static quality, measurement volume and standard volume and density measurement and standard density, To meet the needs Custody transfer measurement. In the custody transfer measurement, the volume or mass number using the number of oil determined by the user, but are still included in this standard Analysis and examples related uncertainty, the purpose is to help you choose the right HTMS component configuration to achieve the desired measurable indicators. This standard applies to stationary vertical cylindrical tanks, which store oil Reid Vapor Pressure (RVP) of less than 103.42kPa. This standard does not apply to cabin pressure tank or for metering. Note 1. The term "quality" is used to indicate vacuum quality (true quality). In the oil industry, the apparent mass (air) commonly used in the business transfer. therefore, Standard calculation method is also provided on the air quality and the apparent quality (see Appendix A). Note 2. The standard calculation method can also be used for other shapes tanks, these tanks have been calibrated by national standard methods. Ball given in Appendix B Calculation example shaped horizontal cylindrical tanks and uncertainty analysis.
