9.6.2 Perform a D3 or D3 and D4 density calibration using
ProLink III
Prerequisites
• During density calibration, the sensor must be completely filled with the calibration
fluid, and flow through the sensor must be at the lowest rate allowed by your
application. This is usually accomplished by closing the shutoff valve downstream
from the sensor, then filling the sensor with the appropriate fluid.
• For D3 density calibration, the D3 fluid must meet the following requirements:
- Minimum density of 0.6 g/cm
3
- Minimum difference of 0.1 g/cm
3
between the density of the D3 fluid and the
density of water. The density of the D3 fluid may be either greater or less than
the density of water.
• For D4 density calibration, the D4 fluid must meet the following requirements:
- Minimum density of 0.6 g/cm
