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, alternative 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.

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

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.

Density, relative density, or API gravity is a factor governing the quality and pricing of crude petroleum. However, this property of petroleum is an uncertain indication of its 1b2 unless correlated with other properties.

It is up to the user to determine whether this test method provides results of sufficient accuracy for the intended purpose. When used in connection with bulk oil measurements, volume correction errors are minimized by observing the hydrometer reading at a temperature close to that of the bulk oil temperature.

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.

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, alternative calibration temperature effects and to the d12988 temperature by means of the Petroleum Measurement Tables; values obtained at other than the reference temperature being hydrometer readings and not density measurements.

If a stable temperature cannot aetm obtained, place the hydrometer cylinder in a constant temperature bath and repeat the procedure from 9.

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.

This effect becomes more important as temperatures diverge from the reference temperature.
