Moisture / Dew Point Analyzer — Biogas Plants
Continuous moisture and dew point monitoring to prevent condensation, corrosion, analyzer damage, and engine failures in biogas and CBG systems.
Technician rule:
Most moisture-related failures are caused by
poor drainage, wrong sample line slope, or missing coolers,
not sensor problems.
Why Moisture Measurement Is Critical
- Prevents corrosion of pipelines and engines
- Avoids liquid water carryover into compressors
- Protects analyzers and flow meters
- Improves reliability of upgrading membranes
What Is Measured
- Moisture concentration (ppm / g/m³)
- Dew point temperature (°C)
- Condensation risk in gas lines
Measurement Technologies
- Capacitive polymer sensors
- Chilled mirror (reference method)
- Aluminum oxide sensors
Typical Installation Locations
- After gas coolers and separators
- Before engines and compressors
- Before upgrading membranes
- Before cascade storage
