Perform a D1 and D2 density calibration using the
Field Communicator
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.
• D1 and D2 density calibration require a D1 (low-density) fluid and a D2 (high-
density) fluid. You may use air and water.
