13. Verify the calibration by inspecting the graph on the right
hand of the window showing the generated polynomial curve
and where the measurement points fit on the curve. Check
that the points are on, or close to the line, to ensure a good
calibration.
4.4.2 Sand noise calibration: varying sand rate with fixed flow
velocity
In this part of the calibration, it is recommended that as a
minimum of three measurement points are used following the
recommendations stated below:
• Sand rate
A minimum of three different sand rates should be chosen which
would be representative of expected conditions during operation.
An example of what could be used is shown below:
— 0.1 g/s
— 1.0 g/s
— 2.0 g/s
• Flow velocity
Flow velocity should remain constant. It is recommended to use
the expected velocity which will be used during operation.
