Fuel Gas Mass Flow Measurement
Reading difference between Totalizator on HMI of 96FM-1 Gas fuel mass flow transmitter and per second (LBS/S) of gas flow Signal (fqguv_TH) reading taken from software.

Hello,

I am working on GE 9HA.01 class gas turbine as I&C Engr. During observation regarding 96FM-1 Gas fuel mass flow transmitter, we observed that there is difference between Totalizator that showing on HMI of 96FM-1 Gas fuel mass flow transmitter and per second (LBS/S) of gas flow Signal(fqguv_TH) reading taken from software (normally generated in excel sheet).

Reading showing on Totalizator window of HMI is 5988 Kg/5mint (After got difference between two 5 mint interval),

Gas flow Signal(fqguv_TH) reading taken from software/Excel sheet is 4843.826871 (After added 300 Seconds)

Now the difference between above two reading is: 1144.173129 Kg/5mint.

Can anyone help me why these two reading difference is coming while the gas flow signal is same?

Regards,

You'll need to ask GE Belfort.
