Chapter 10
Measurement Performance
10.1
Overview
This chapter describes the following procedures:
•
Meter verification – see Section 10.3
•
Meter validation and adjusting meter factors – see Section 10.4
•
Density calibration – see Section 10.5
•
Temperature calibration – see Section 10.6
This chapter provides basic information and procedural flowcharts for each step. For more details
about how to perform each procedure, see the flowcharts for your transmitter and communication
tool, provided in the appendices to this manual.
Notes: All ProLink II procedures provided in this section assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Chapter 3 for more
information.
All Communicator key sequences in this section assume that you are starting from the "Online"
menu. See Chapter 4 for more information.
10.2
Meter verification, meter validation, and calibration
There are three procedures:
•
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
All Series 1000/2000 transmitters can be validated and calibrated. If the transmitter is connected to an
enhanced core processor, meter verification may be supported depending on whether the transmitter
was ordered with this option.
These three procedures are discussed and compared in Sections 10.2.1 through 10.2.4. Before
performing any of these procedures, review these sections to ensure that you will be performing the
appropriate procedure for your purposes.
