AGA-7 Turbine and Ultrasonic Meter Configuration on ABB Totalflow
Key Takeaway
How to configure AGA-7 flow measurement for turbine meters on ABB Totalflow — pulse input, K-factor, meter factor, pressure/temperature compensation.
Quick Answer
AGA-7 configuration on Totalflow involves creating an AGA-7 application, assigning the turbine meter pulse input, entering the K-factor and meter factor, and configuring pressure and temperature compensation inputs for standard volume calculation.
Configuration
- Create AGA-7 application in PCCU32
- Assign pulse input channel for turbine meter
- Enter K-factor (pulses per unit volume from manufacturer)
- Enter meter factor (from proving, default 1.0000)
- Assign static pressure and temperature inputs
- Configure gas composition and compressibility method
- Set base conditions and alarm limits
- Configure archive intervals
K-Factor
The K-factor converts pulse counts to volumetric flow. It is provided by the meter manufacturer and verified during proving.
Meter Factor
Applied as a multiplier to correct for meter accuracy deviation from the prover reference. Updated after each proving event.
Frequently Asked Questions
