How to perform flow accumulation using S7300, as well as carry out compensation for steam flow, temperature, and pressure. . Who can tell me? Thank you
For cumulative flow volume, please refer to the mathematical principles behind points. Steam correction can be carried out using density lookup tables; detailed information and density table data are available online. Of course, it is also possible to use formula-based calculations, though these formulas are quite complex and there are different versions of them (two versions according to international standards). It is recommended to use the density lookup table method
In OB35, by default the scanning cycle is 100 ms, which means data is accumulated every 0.1 seconds; a reset function can also be set up. Thermal and pressure compensation reference formula.
