We want to calculate the gas flow rate in the GE turbines without installation flow meter. please help me how we can measure the flow by the FSR value? our turbine are ge frame 5
It would be very expensive to install the instrumentation necessary to equate Gas Control Valve position to fuel flow-rate with any degree of accuracy and repeatability.
And, the accuracy of LVDT calibration would be very critical as well.
You would also need to know the Cv of the Gas Control Valve, and that's not easy to obtain from GE, and it can, and quite often does, change when valves are refurbished (because non-GE internal components are used, or because incorrect internal components are installed for any number of various and sundry reasons).
This would not be a good method of measuring gas fuel flow-rate.
If you have a run of pipe that is of sufficient length-versus-diameter, there are various methods of "sonic" or other methods of measurement.
And, then the purpose of this measurement would be a very important part of the determining factor of the type of measurement method to be used (in other words, does it need to be revenue quality, or lesser, and if lesser, then how much lesser is acceptable).
Best to start from the need/application and work from there. And, while it's technically feasible to calculate gas fuel flow-rate from LVDT feedback, it likely would not be very accurate for very long given how quick people are to "calibrate" LVDT feedback at the drop of a hat, er, ..., uh, ..., for any slight reason or just maybe because there is a second full moon in this calendar month (also known as a "blue moon"). And, we all know that LVDT calibrations are notoriously inaccurate and usually performed without any verification of actual physical position versus LVDT feedback. Just, wham, bam, thank you, ma'am is the usual process (sometimes without even the thank you!).
Not recommended.
