Methane analyzer GA220

carbon dioxidemonitoringprocess

Overview The Gas Analyzer 220 - Biomethan is a stationary online gas analyzer optimized for precise, long-term stable measurement of high methane concentrations (biomethane). Designed for demanding process environments, it provides drift-free results, fast response and straightforward integration into industrial control systems.

Application The Gas Analyzer 220 - Biomethan is developed for continuous online monitoring of methane in biomethane production and upgrading. Measurement range: 0.1–100 Vol.-% CH₄. Robust measurement control and automated zero-point correction ensure reliable data under variable process conditions.

Features

• High long-term stability: patented automatic zero-point correction minimizes drift.
• Built-in sampling: integrated membrane pump for autonomous sample supply at ~4 l/min.
• Extensive interfaces: RS232 (standard); optional Profibus DP, Ethernet Modbus TCP, Profinet; up to 8 analogue outputs (4–20 mA).
• User interface: 128 × 64 pixel monochrome touch display for intuitive operation and quick parameter changes.
• Compact industrial housing: 19" rack-mount (400 mm depth), protection class IP20.

Use cases

• Biomethane plants: continuous CH₄ monitoring for process control and product quality assurance.
