MilliGascounters Low Flow Volumetric Gas Flowmeter

• Minimum flow rate 1 ml/h
• Maximum flow rate 1 ltr/h
• Resolution 3 ml
• Accuracy ± 3 % of reading across full flow rate range; in combination with »RIGAMO« software better than ±1 %
• Use with inert and medium corrosive gases (biogas) as well as highly aggressive gases
• Materials: Plexiglas (PMMA), PVDF, PVC (red)
• Digital counter with programmed calibration factor
• Battery operated; battery life-time 3-4 years
• Low-maintenance

• Individual volumetric calibration of each MilliGascounter traceable to the German National Primary Standard (PTB)
• Total gas production measured (instead of Methane only)
• Head space volume of fermentation bottle at measurement start (= air) not erroneously measured as pure methane volume

RITTER MilliGascounters ⁽¹⁾ (MGC) are designed for the volumetric measurement of the smallest amounts of gas with ultra-low flow rates. They are suitable for measurement of all inert, slightly corrosive gases such as biogas (PMMA model) and aggressive gases (PVDF model). Furthermore, MilliGascounters can be used for volumetric leak detection. ⁽¹⁾ Developed at the University of Applied Sciences Hamburg, Prof. Dr. Paul A. Scherer
