![]() ![]() ![]() This is also inaccurate for extremely low flow, or elevated pressure.Ĭonversion factors should not be used for variable are flow meters with ball floats.Ĭonsult Applications Engineering for your specific condition. To aid with this we have highlighted the range of 34ppt-36ppt in green. You can also work out what your specific gravity should be at a certain temperature if you are keeping your water at around 35ppt. Please note: this correction factor is only accurate within ☑0%. Using the chart below you can work out what the actual salinity of water is based on your specific gravity and temperature. Calculator description Calculator use following equations for conversion between API and Baume degrees. The left and right margins of the table are annotated with the temperature. To convert an API gravity reading to 60☏, we usually use ASTM Table 5B. This will equal an approximation of the flowrate of the gas being used. Conversion in Baume degrees is for liquids with specific gravity higher or lower than 1, which means for liquids heavier or lighter than water. 1) Usually, your API gravity reading will be at a temperature other than 60☏. Note that relative specific gravity (sg) and conductivity (mS/cm) measurements are inheritly temperature-dependent and that this calculator follows the prevailing standard of assuming a temperature of 25C/77F. We know from high school science that water weighs 8.34 (8.3369) pounds per US gallon. Multiply the flowrate indicated on the meter by the correction factor. This calculator converts between various units of salinity. Specific Gravity, on the other hand, is defined as the weight of a sample, at a given temperature, divided by the weight of the same volume of water. Water has a specific gravity of 1.000 at 68F (room temperature). To determine corrected flowrate: find the gas for which the meter is calibrated in the left column, move to the right to the gas that is being used.
