Chapter 9
Measurement support
Topics covered in this chapter:
♦ Options for measurement support
♦ Validate the meter
♦ Perform a (standard) D1 and D2 density calibration
♦ Perform a D3 and D4 density calibration (T-Series sensors only)
♦ Perform temperature calibration
9.1
Options for measurement support
Micro Motion provides several measurement support procedures to help you evaluate and maintain
your flowmeter's accuracy.
The following methods are available:
• Meter validation compares flowmeter measurements reported by the transmitter to an external
measurement standard. Meter validation requires one data point.
• Calibration establishes the relationship between a process variable and the signal produced at
the sensor. You can calibrate the flowmeter for zero, density, and temperature. Density and
temperature calibration require two data points (low and high) and an external measurement for
each.
Tip
Micro Motion recommends using meter validation and meter factors, rather than calibration, to prove the
meter against a regulatory standard or to correct measurement error.
9.2
Validate the meter
Meter validation compares flowmeter measurements reported by the transmitter to an external
measurement standard. If the transmitter mass flow, volume flow, or density measurement is significantly
different from the external measurement standard, you may want to adjust the corresponding meter
factor. The flowmeter’s actual measurement is multiplied by the meter factor, and the resulting value is
reported and used in further processing.
