How to Configure an AGA-7 Turbine Meter on the Emerson ROC800
Key Takeaway
Step-by-step AGA-7 turbine meter configuration on the ROC800 — pulse input, K-factor, meter factor, pressure/temperature compensation, and proving records.
Quick Answer
An AGA-7 meter run on the ROC800 calculates gas volume from turbine meter pulse inputs using the K-factor, meter factor, and gas composition corrections. Configure in ROCLINK 800 under Meter Runs with pulse input assignment, K-factor from the meter nameplate, and pressure/temperature compensation inputs.
How Do You Create an AGA-7 Meter Run?
- Navigate to Meter Runs in ROCLINK 800
- Set Meter Type to AGA-7 Turbine
- Assign pulse input channel
- Enter K-factor (pulses per unit volume)
- Enter meter factor (1.0000 from proving)
- Assign static pressure and temperature inputs
- Configure gas composition and compressibility
- Set base conditions and alarm limits
- Write and verify calculated volumes
What Is the K-Factor?
The number of pulses per unit volume from the meter manufacturer. Used to convert pulse counts to volumetric flow.
What Is the Meter Factor?
A correction multiplier from meter proving that accounts for accuracy deviation. Updated after each proving event. Default 1.0000.
For comparison, see AGA-7 on ABB Totalflow and ROC pulse input configuration.
