The following equation is mathematically equivalent to the first equation. You may use whichever
MeterFactor
version you prefer.
3. Ensure that the calculated meter factor does not fall outside 0.98 and 1.02. If the meter factor is
outside these limits, contact customer service.
4. Configure the meter factor for volume flow in the transmitter.

14.6 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.
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.
If LD Optimization is enabled on your meter, disable it. To do this using the Field Communicator, choose
•
Configure > Manual Setup > Measurements > Optional Setup > LD Optimization. LD Optimization is
used only with large sensors in hydrocarbon applications. If you are not using the Field Communicator,
contact Micro Motion before continuing.
• 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.
