Matematica/Example_1
Simplified calculation systems for standardized dp-flowmeters (orifice…) often calculates flow=k*sqrt(dp).
This can generate an error of>10%.

How can this be realized?
In 3 steps;
1. The knowledge/math is ”on the shelf”.
2. Computers like PC/control system are also ”on the shelf”.
3. The knowledge/math are moved from the bookshelf to the computers without compromises.

Ex; With Processline You can:
1.Identify flow calculation errors.
2.Eliminate the errors with better code.
3.Automatic generate the code with a click on Procesline Kodfabriken/Bigblock Tag
4.Build a ”blindtarm” (dead end) that works side by side with the old code (if any).
5.Put the new code to work when it’s proven stable.
Point 1-5 can reduce calculation errors from sometimes >10 to < 0.01%.
