  18. Testing Heavy BrinesAPI 13 J – ISO DIS 13503-3 Hydrometers & Density measurements Bernard Fraboulet, TOTAL Technology Specialists API Exploration & Production Standards Winter Meeting Fort Worth , January 26th, 2011

  19. Density & specific gravity measurements • Hydrometers • Density hydrometer • Concept : mass per unit of volume (ρ) • SI Graduations in g/ml - kg/m3 • USC Graduations in ppg • Reference temperatures • SI 20°C • USC : 70°C ( 21.1°C) • Relative density (specific gravity) hydrometer • Concept : ratio of ρ sample by ρ water at the same temperature • Graduation dimensionless • Reference temperature 15.56°C /60°F • Ratio of sample density to water density at 60°F : • 999,012 kg/m3 ≡ 0, 999 012 g/ml (8,337 ppg)

  20. Hydrometer and normative references • ISO 387: 1977 Principles of construction and adjustment • ISO 649:1981 Density hydrometer for general purposes • part 1 : Specifications • Part 2 : Test methods and use • for both part : no adoption by USA • ISO 650 :1977 Relative density 60/60°F hydrometers for general purposes • Not adoption by France and Germany and then by CEN

  21. Reference & Reporting temperature • ISO 387 Reference temperature • Clause 4.1 - density hydrometer : • 20 °C (68°F) • In special circumstances : substitution to 15°C (59°F) or 27°C (80.6°F) • 27°C i.e 80°F recommended • other reference temperatures ? USA : 70 °F ? • Clause 4.2 : relative density hydrometer • 60°F ( 15,56°C) for liquid and water • Density reporting temperature • For any measurement done at a temperature which is not the reference one, a correction is required. • General reporting : when density hydrometer is used why to report at a different temperature than the reference ’s one ? • Does it need to get a direct conversion between SI ref. temperature to USC’s (20°C – 68°F) or between USC ref. temperature to SI’s (70°F – 21°C) ? • Reporting temperature proposal : • SI report : 20°C USC report : 70°F Left to users

  22. Clause 6.2.1 Hydrometer description • More accurate description • As per ISO’s : class M100 hydrometer • 6.2.1.1 Density hydrometer • 6.2.2.1 Relative density hydrometer • Calibration : • at least quarterly

  23. Temperature Correction factor • Density hydrometer • Only a correction linked to hydrometer volumetric change is required : • Standard glass thermal volume expansion 20 x 10-6 • Table linked to readings and temperature • Minor difference lower than uncertainty if the same table is used for 20°C or 70°F as reference temperature • Two tables ( SI and USC) possible

  24. Temperature Correction factor • Relative density hydrometer • Reference temperature 60°F • Correction whatever the reporting temperature • Correction linked to • Glass volumetric change • Water temperature density variation • Correction factor : • Complex equation • tables of coefficient • variations as per author/references

  25. Proposed changes • Clause 6.4.1 Temperature correction for hydrometer • 6.4.1.1 Density hydrometer • Correction factor (unit kg/m3 or 10-3 g/ml) • 6.4.1.2 Relative density hydrometer • sub clause 6.4.1 • no changes • Add SI equations
