Is there any work done on estimating installed orifice plate for turn down operation. Many time after we selected a plate for a classical 3:1 turn down assuming known accuracy, we would face a question from the field on how much we can stretch the accuracy statement we assumed in design.
On the other hand, we run orifice calculations to select a plate good for 10:1 turn down typically focus on design case and allowable pressure loss, not on the extreme turn down case. How do we estimate the uncertainty in turn down cases?
