AGA10 Speed of Sound Calculations

Daniel Ultrasonic Flow Meters can save valuable time with real-time AGA10 SOS calculations. The Mark III Electronics, using live gas composition, pressure and temperature, calculates the speed of sound every 5 seconds. The AGA10-calculated and meter-measured SOS values are then averaged over an hour with the results reported in an hourly data log. This comparison can help identify possible process upsets and can validate the integrity of the flow meter, gas analysis and analog measurements.

The Daniel Customer Ultrasonic Interface (CUI) software automatically includes the AGA10-calculated SOS in the inspection reports. This valuable feature prevents manual gas composition data entry errors.
