DRUM-TYPE GAS METERS

RITTER drum gas meters can be used universally for measuring the volume of flowing gases, especially for small and medium flow rates, e.g. in laboratories, where the highest level of precision is required. Highest measuring accuracy of ±0.5% over the entire measuring range.

The possibility of selecting the gas meter material from among 5 different excellent materials: Polyvinyl Chloride (PVC), Polypropylene (PP), Polyvinylide Fluoride (PVDF), PE-el (polyethylene electrically conductive) or refined stainless steel 1.4571 (316 Ti) enables the user individually to meet measurement requirements even in case of highly aggressive gases.

User Benefits

  •  Highest accuracy: ±0,5% across full flow rate range
  •  Calibration traceable to the German National Primary Standard (PTB)
  •  Measurement of all gases and gas mixtures with equal accuracy
  •  Use with extremely corrosive and inert gases.
  •  Lowest measurable flow rates
  •  Largest selection of measuring ranges
  •  Real time data acquisition option for PC (requires option »Pulse Generator«)
  •  Most durable construction – available, both chemically (from high-quality thermoplastics) and mechanically (stainless steel)
  •  Maintenance-free (just checking of packing liquid level required)

Standard Equipment

  • Multi-Chamber Measuring Drum
  • Magnetic coupling between measuring drum and counter (for an absolutely liquid-tight casing)
  • 8 or 9-digit Totalizing Roller Counter
  • Large One-needle Dial
  • Supports for Thermometer and Manometer
  • Viton sealing
  • Level and Levelling Feet
  • Bubble level for levelling

(1) The calibration is performed at standard flow and 20 °C (68 °F)
(2) Minimum dial division

The maximum gas inlet overpressure is dependent on the gas meter type and casing material:

  • With plastic casings TG05 – TG5: Standard version 50 mbar
  • With plastic casings TG10 – TG50: 50 mbar
  • With stainless steel casings: 0.5 to 40 bar

Measuring accuracy: ± 0.2% at standard flow rate (exact value is stated in individual Calibration Certificate) and approx. ± 0.5% across the entire measuring range.
