UKTN TNflow v3.10
TNflow is addressing the needs of engineers dealing with fluid flow measurement by means of pressure differential devices. TNflow may be used to calculate:
primary device diameter (bore diameter) for declared full scale flowrate and related value of differential pressure;
differential pressure for declared bore diameter and flowrate;
flowrate for declared bore diameter and differential pressure.
Any of the above calculations is supplemanted by:
diameters corrections for thermal expansion;
bounds of measurement range calculations;
upper limit of upstream pipe roughness calculations;
upper limit of sharp edge radius calculations;
required upstream and downstream straight lengths calculations;
uncertainty analysis of flowrate measurement at a single point and in the entire measurement range;
