FAQ
Q1: What detection technology does it use, and which gases can it measure?
A1: It uses imported NDIR or TDLAS technology. Standard configuration measures CH₄ and CₙHₘ and calculates HHV/LHV. Optional modules support CO₂, CO, O₂, H₂S, and H₂O-fully customizable to your application.
Q2: Is the accuracy and speed sufficient for real-time pipeline monitoring?
A2: Absolutely. With ±1% F.S. accuracy, 0.01% resolution, and ≤10-second response time, it provides fast, reliable data for dynamic gas quality control and custody transfer.
Q3: What are the installation and sample gas requirements?
A3: Operating environment: –5°C to 50°C, 0–90% RH. Sample gas must be at 0.1–0.5 MPa pressure, 500 mL/min flow, and –5°C to 50°C. A pre-filter and pressure regulator are recommended for long-term stability.
Q4: Is operation simple? Can I view historical data?
A4: Yes! The intuitive touchscreen interface allows one-touch access to real-time values, historical trends, and alarm logs. Data can be queried by time, exported, and averaged-ideal for reporting and troubleshooting.
Q5: How is data output handled? Does it need special power?
A5: Standard outputs include 4–20 mA and RS-485; USB is optional. Power is standard 220 V AC-no special wiring or transformers required.
