RITTER TG Drum-Type Gas Meters
Primary-standard volumetric gas measurement – accurate, reproducible, independent
Direct volumetric measurement you can rely on
RITTER TG drum-type gas meters operate on a true volumetric displacement principle. Gas volume is measured directly by a rotating drum immersed in a sealing liquid — not inferred from heat capacity, gas flow rate, temperature, pressure, or gas composition.
As a result, TG meters deliver highly reproducible and traceable results, independent of gas type, humidity, temperature fluctuations, or contaminants.
Technical Highlights
- High measurement accuracy
±0.2 % at nominal flow rate; approx. ±0.5 % across the entire measuring range - Wide flow range
Models covering 1 L/h up to 18,000 L/h, enabling precise measurement from low lab flow rates to industrial flow rates - Gas-independent performance
Suitable for pure gases, gas mixtures, humid gases, aggressive or corrosive media - Material flexibility
Drum and housing available in PVC, PP, PVDF, electrically conductive PE-el or stainless steel — optimized for chemical resistance and long-term stability - Exceptional durability
Welded drum construction using identical materials ensures long service life even in demanding laboratory and industrial environments - Optional digital integration
Pulse generator, electronic display and PC connection via RIGAMO software for automated data acquisition and long-term monitoring
Typical Scientific Applications
- Calibration of flow meters and gas sensors
