21.2.2 Meter validation and meter factors
Meter validation can be used with all Series 3000 systems (both transmitters and controllers). There
are no special requirements.
Meter validation compares a measurement value reported by the Series 3000 device with an external
measurement standard. Meter validation requires one data point.
Note: For meter validation to be useful, the external measurement standard must be more accurate
than the sensor. See the sensor’s product data sheet for its accuracy specification.
If the Series 3000 device’s mass flow, volume flow, or density measurement is significantly different
from the external measurement standard, you may want to adjust the corresponding meter factor. A
meter factor is the value by which the Series 3000 device multiplies the process variable value. The
default meter factors are
1.0, resulting in no difference between the data retrieved from the sensor and
the data reported externally.
Meter factors are typically used for proving the flowmeter against a weights and measures standard.
You may need to calculate and adjust meter factors periodically to comply with regulations.
21.2.3 Calibration
Calibration applies only to the Model 3500 and Model 3700 transmitters. There are no special
requirements.
