Calibration
3.1 Overview
This chapter describes the following procedures:
• Characterization (Section 3.3)
• Smart Meter Verification (Section 3.4)
• Meter validation and adjusting meter factors (Section 3.5)
• Zero calibration (Section 3.6)
• Density calibration (Section 3.7)
• Temperature calibration (Section 3.8)
Note: All procedures provided in this chapter assume that you have established communication with
the transmitter and that you are complying with all applicable safety requirements. See Appendix C or
the documentation for your PROFIBUS host or configuration tool.
3.2 Characterization, Smart Meter Verification, meter validation, and calibration
There are four procedures:
• Characterization – adjusts the transmitter to compensate for the unique traits of the sensor
with which it is paired
• Smart Meter Verification – establishing confidence in the sensor’s performance by analyzing
secondary variables that are highly correlated with flow and density calibration factors
• Meter validation – confirming performance by comparing the sensor’s measurements to a
primary standard
• Calibration – establishing the relationship between a process variable (flow, density, or
temperature) and the signal produced by the sensor, or establishing the transmitter’s response
to a zero-flow condition.
Meter validation, characterization, and calibration are available on all Model 2700 transmitters. Smart
Meter Verification is available only if the Smart Meter Verification option was ordered with the
transmitter.
These four procedures are discussed and compared in Sections 3.2.1 through 3.2.4. Before performing
any of these procedures, review these sections to ensure that you will be performing the appropriate
procedure for your purposes.
