10.To verify the accuracy of the temperature calibration factor, repeat
steps 5 through 8. The measured temperature of the process fluid
should equal the temperature indicated in the Process Variables
window.
11.Recalibrate the flowmeter:
a. Perform the flow calibration procedure described in
Section 8.2
,
page 73.
b. Perform the density calibration procedure described in
Section 14.4
, page 138.
c. Perform the viscosity calibration procedure described in
Section 14.5
, page 148.
Example:
Given:
• The measured temperature of the low-temperature process fluid is
20.0°C (T
1
= 20).
• The Process Variables window indicates a temperature of 20.1°C
when the flow tubes contain the low-temperature process fluid
(T
2
=20.1).
• The measured temperature of the high-temperature process fluid is
80.0°C (T
3
= 80).
• The Process Variables window indicates a temperature of 80.3°C
when the flow tubes contain the high-temperature process fluid
(T
4
=80.3).
Problem:
Determine the temperature calibration factor. Follow these
steps:
Solve for A:
A = (T
3
– T
1
) / (T
4
– T
2
)
= (80 – 20) / (80.3 – 20.1)
= 0.99668
Solve for B:
B = T
1
– A(T
2
) = T
3
– A(T
4
)
= 20 – 0.99668(20.1) ≅ 80 – 0.99668(80.3)
= –0.0333
The temperature calibration factor is:
K = 0.99668T–0.0333
