- 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 mbar and 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.
