Perform A (Standard) D1 And D2 Density Calibration; Perform A D1 And D2 Density Calibration Using The Display - Emerson Micro Motion 5700 Configuration And Use Manual

12.5 Perform a (standard) D1 and D2 density
calibration
Density calibration establishes the relationship between the density of the calibration
fluids and the signal produced at the sensor. Density calibration includes the calibration of
the D1 (low-density) and D2 (high-density) calibration points.
Important
Micro Motion flowmeters are calibrated at the factory, and normally do not need to be calibrated in
the field. Calibrate the flowmeter only if you must do so to meet regulatory requirements. Contact
customer support before calibrating the flowmeter.
Tip
Use meter validation and meter factors, rather than calibration, to prove the meter against a
regulatory standard or to correct measurement error.

Configuration and Use Manual
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.
The calibrations must be performed without interruption, in the order shown. Make
sure that you are prepared to complete the process without interruption.
Before performing the calibration, record your current calibration parameters. You
can do this by saving the current configuration to a file on the PC. If the calibration
fails, restore the known values.
