Product Details

RITTER Drum-type (wet-test) Gas Meters are universally applicable for measuring the volume of flowing gases and are particularly effective when measurements demand the highest precision. Our Drum-type Gas Meters are specifically designed for use with corrosive gases. They are made out of a selection of 4 superior plastics (PVC, PP, PVDF and electrically-conductive PE). A gas meter can therefore be selected which is completely resistant to the corrosive gases being measured. Stainless steel is not completely resistant to corrosive gases and will be damaged by them over time.

Features

  • 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)

(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: 50 to 500 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.
