FAQ – Gas Ultrasonic Flow Meters

Q1: What is the main application of gas ultrasonic flow meters?
A1: They are primarily used for custody transfer and pipeline monitoring of natural gas, ensuring accurate measurement in high‑volume transmission systems.

Q2: How accurate are these meters?
A2: Accuracy ranges from ±0.2% (calibrated, custody transfer models like Rosemount 3418 or Elster Q.Sonic Plus) to ±0.3% (monitoring models like KROHNE ALTOSONIC V or SICK FLOWSIC600).

Q3: What is the difference between custody transfer and non‑custody transfer models?
A3: Custody transfer models (e.g., Rosemount 3418, Elster Q.Sonic Plus) are designed for commercial transactions where precision and compliance are critical. Non‑custody transfer models (e.g., Rosemount USM 3410/3412) are used for pipeline balance, storage, and internal monitoring.

Q4: How do path configurations affect performance?
A4: More paths (6–8) provide redundancy and higher accuracy for custody transfer. Fewer paths (2–4) are sufficient for monitoring and balance applications, offering cost efficiency.

Q5: What are the key advantages compared to traditional flow meters?
A5:

• No moving parts → lower maintenance
• High accuracy and repeatability
• Advanced diagnostics and self‑monitoring
• Compliance with international standards (ISO, AGA)

Q6: Which industries typically use these meters?
A6: Natural gas transmission, distribution companies, power plants, and industrial facilities requiring precise gas measurement.
