Here is the SIZEWELL online sizing tool for differential pressure flow elements.
It is an esay-to-use software: you fill in the data of your fluid and process, the software carries out preliminary calculations and directs you to the most suitable flow measurement elements. All that remains is to make your choice among all the available elements and consult the corresponding datasheets.
This tool also allows you to enter all the data necessary for the sizing of restriction orifices (pressure reduction & flow limitation devices). You validate your project and data is sent directly to our project managers; the calculations are carried out more quickly by our engineering office as well as the recommendations in terms of number of stages and orifices.
