Process Trace Moisture Analyzer for Hydrogen Metering and Gas Grid Infeed Plants
Hydrogen produced from renewable electricity is increasingly used to balance fluctuating energy supply from wind and solar sources. Electrolysis units convert water into hydrogen and oxygen through controlled electron exchange, typically arranged in stacks to achieve high throughput and purity. After production, hydrogen is conditioned, analyzed and metered before entering the natural gas grid or downstream processes. Moisture content is a critical parameter, especially when additional compression is required. Exceeding feed‑in limits - such as 50 mg/m³- can lead to condensation, corrosion, erosion, hydrate formation and operational safety risks. Reliable, stable and low‑maintenance moisture measurement is therefore essential, particularly for unmanned or offshore installations.
BARTEC presents the PMA‑5674 Process Trace Moisture Analyzer as a robust and industry‑proven solution for hydrogen production and natural‑gas grid infeed applications. Designed for demanding environments, the PMA‑5674 uses an optical thin‑film Fabry‑Pérot interferometer to deliver precise trace‑moisture readings independent of intensity fluctuations and over long fiber‑optic distances up to 800 meters. The system provides dew‑point temperature, water vapor pressure, ppmv, mg/m³ and additional parameters, with optional ISO‑compliant calculations. Its rugged sensor design withstands water slugs, ensures long‑term stability and enables easy maintenance through sensor‑retraction armatures. With thousands of installations worldwide, BARTEC’s PMA‑5674 offers proven reliability, flexible integration, and certified safety for hydrogen, LNG, petrochemical and specialty‑gas operations.
