I have doubts about flow calculations of Foundation Fieldbus Flow Transmitter, field range is 0~30 mbar and DCS system side range is 0~38240 Kg/hr.
How can I write in loop folder(25 %, 50 %, 75%) 25% how much mbar can I apply in Field.and what reading in show dcs in the same time.
Because in loop folder have 2 colum one is input applied (EU) and 2nd is ICSS Reading (EU) .
Anyone tell me calculation with example
Thanks

I do not fully understand the question, but it seems you have a orrife plate what is used as a delta pressure flow meter.
When the delta pressure reads:
- 0 mbar, then DCS will give 0 kg/hr [0%];
- 30 mbar, then DCS will give 38240 kg/hr [100%].
So, for 25% it will be:
- 7.5 mbar, then DCS will give 9560 kg/hr;
For 50% it will be:
- 15 mbar, then DCS will give 19120 kg/hr;
For 75% it will be:
- 22.5 mbar, then DCS will give 28680 kg/hr.
