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
• Zero calibration – see Section 10.5
• Density calibration – see Section 10.6
• Temperature calibration – see Section 10.7
Note: All ProLink II procedures provided in this chapter assume that you have established
communication between ProLink II and the Model 2400S DN transmitter and that you are complying
with all applicable safety requirements. See Chapter 4 for more information.
Note: If you are using Pocket ProLink, the interface is similar to the ProLink II interface described in
this chapter, with the exception that the additional meter verification functionality described in
Section 10.3.2 is not available.
Note: All DeviceNet tool procedures provided in this chapter assume that you have established
communication between the DeviceNet tool and the Model 2400S DN transmitter and that you are
complying with all applicable safety requirements. See Chapter 5 for more information.
10.2 Meter validation, meter verification, and calibration
The Model 2400S transmitter supports the following procedures for the evaluation and adjustment of
measurement performance:
• Meter verification – establishing confidence in the sensor’s performance by analyzing
secondary variables associated with flow and density
• 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
Meter validation and calibration are available on all Model 2400S DN transmitters. Meter verification
is available only if the meter verification option was ordered with the transmitter.
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.
