Features
• Measures velocity, volumetric and mass flow
• Independent of gas composition
• Measures instantaneous average molecular weight
• High velocity range to 120 m/s (394 ft/s)
• Accurate low flow rate measurement
• 4000 to 1 turndown ratio
• One or two path configurations
• Allows cross flow immunity in large pipes
• Minimal maintenance due to no moving parts, no holes or
tubes, and tolerance to dirty or wet conditions
• No pressure drop
• Field-proven installation techniques
• Easy serviceability

Applications
The DigitalFlow XGF868i flowmeter is a complete
ultrasonic flow metering system for:
• Flare gas
• Track down or prevent losses from leakage with positive
material identification
• Measures Net Heating Value (NHV) of vent gas in BTU/SCF,
MJ/m3, or KJ/m3
• Account for total plant throughput of material
• Reduce cost of steam usage with proportional control
• Conserve energy by eliminating unnecessary flaring
• Comply with government regulations for pollution control
• Vent gas
• Hydrocarbon gases
• Biogases
• Digester gases
