Measurement Performance
21.1 Overview
This chapter describes the following procedures:
• Meter verification – see Section 21.3
• Meter validation and adjusting meter factors – see Section 21.4
• Density calibration – see Section 21.5
• Temperature calibration – see Section 21.6
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 Series 3000 device and
communication tool, provided in the appendices to this manual.
Notes: All ProLink II or Communicator procedures provided in this section assume that your
computer is already connected to the Series 3000 device and you have established communication,
and that you are complying with all applicable safety requirements.
21.2 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
These three procedures are discussed and compared in Sections 21.2.1 through 21.2.4. Before
performing any of these procedures, review these sections to ensure that you will be performing the
appropriate procedure for your purposes.
