The calculations required in Section 10 shall be applied to the initial hydrometer reading with observations and results reported as required by Section 11 prior to use in a subsequent calculation procedure ticket calculation, meter factor calculation, or base prover volume determination.

This procedure can also be used for viscous liquids by allowing e1298 time for the hydrometer to reach temperature equilibrium, and for opaque liquids by employing a suitable meniscus correction.

D — 12b Designation: You may delete a document from your Alert Profile at any time. They shall not become opaque under prolonged exposure to sunlight.

This standard is not included in any packages. The precision of WAT for crude petroleum using this technique has not been determined.

Example Crude Oil 2 5. This reading readin g requi requires res a meniscu meniscuss corre correction. Ensure that the remainder remainder of the hydromet hydrometer er stem stem, whi which ch is abo above ve the liquid level, is not wetted as liquid on the stem affects the reading obtained. It will return API or R. Warning— Warning—Do Do not siphon by mouth as it could result in ingestion of sample! Readings are measured on a hydrometer at either the reference temperature or at another convenient temperature, and readings are corrected for the meniscus effect, the thermal glass expansion effect, alternate calibration temperature effects and to the reference temperature by means of the Petroleum Measurement Tables; values obtained at other than the reference temperature being hydrometer readings and not density measurements.

These values are 4 5. This procedure can also be used for viscous liquids by allowing sufficient time astk the hydrometer to reach temperature equilibrium, and for opaque liquids by employing a suitable meniscus correction.
