One Thermal Flow Meter Manages In-the-Field Changes in Flare Gas Composition Without Factory Re-Cal
QuadraTherm 640i
- Achieve high accuracy +/- 0.75% of reading
- Handles low flows to high flows during upset conditions
- Use qMix™ software to easily change gas composition in the field and retain accuracy
- Use qMix-RealTime™ software to connect, read, and automatically update new gas compositions from a gas chromatograph — real time
- Measures very low pressure vapors with no pressure loss
- Validate in the field for easy in-situ calibration

QuadraTherm 780i
- Achieve the highest accuracy +/- 0.5% of reading
- Handles low flows to high flows during upset conditions
- Use qMix software to easily change gas composition in the field and retain accuracy
- Use qMix-RealTime™ software to connect, read, and automatically update new gas compositions from a gas chromatograph — real time
- Reduce straight-run requirements with built-in flow conditioning
- Validate in the field for easy in-situ calibration

qMix App
- Select gas, customize gas composition percentages, and create new gas mixture in-the-field
- Upload new gas composition to the meter in the field — only takes 3 seconds
- Retain accuracy without sending the meter back to the factory for recalibration
- Use qMix-RealTime™ software to connect, read, and automatically update new gas compositions from a gas chromatograph — real time
- Gain access to all AGA compliant gas properties needed to make the algorithmic gas mass flow rate calculations
