Hi
We are having GE Frame 6B Gas turbines in our plants. For Fuel Gas Flow Measurement, they employ two differential pressure transmitters, one for high dp and one for low dp. Furthemore, they also employ one pressure transmitter and one temperature transmitter for so called pressure and temperature compensation.
I'm interested in knowing the formula which they use to calculate the compensated Fuel Gas Flow. I had a chance to see in the Mark VI control system, where these inputs are feeded to the block called GASFLWC1 which finally outputs the Mass Flowrate QM. The block has the following inputs:
Pressure
Temperature
High DP
Low DP
FQKGDB (0.25 inH2O)
FQKGSG (0.634502) Specific Gravity
GQKGG (2.047 n/d) Gas Constant
Can anybody tell me what formula they have employed with the above mentioned inputs to calculate the compensated mass flow rate QM?
Regards
