Hello,

I am attempting to temperature compensate a liquid propane flow using the AGA function block and have a few questions to see if I am doing this correctly. My setup is as follows:

• Turbine meter that I am reading via a PIN
• I have a temperature at the meter
• There is a chromatograph upstream that provides SG and component %'s

I have configured the block as follows:

• Meter_Type: Turbine
• Den_Base: 30.74 lbs/ft3 (converted from 4.11 lbs/gal)
• Den_Flw: 31.09 lbs/ft3 (converted from chromatographs SG)
• Configured Gas_Comp
  • Ethane: 6.26
  • Propane: 92.25
  • Iso-Butane: 1.46
  • N-Butane: 0.034
• Wired in the temperature transmitter (deg F) to Temp_In
• Wired in the flow to In, converted to ft3/hr
• AGA8_OPT: Manual

My questions are:

1. Should AGA8_OPT be set to Manual for liquid flow w/turbine meter?
2. Is this configuration correct?
3. Am I missing anything?

Thank you
