Performance Data

• ⁽¹⁾ Because of the physical measurement principle, the measurement error is dependent on the flow rate. The data acquisition software »RIGAMO« (accessory) provides an algorithm, which automatically recalculates the actual measurement data to the real values at the respective actual flow rate on the basis of the calibration curve. Thus, the remaining error can be reduced significantly or the flow rate range can be extended at the constant measurement error of ±3%. The remaining error is better than approx. ±1% across the full flow rate range.
• ⁽²⁾ = Nominal value; exact value will be determined by individual calibration
• ⁽³⁾ = Volume of measuring chamber
• ⁽⁴⁾ For complete MGC unit applies: With temperatures > room temperature (e.g. if placed in heating furnace) a foam formation of the packing liquid was monitored in particular cases.
• ⁽⁵⁾ The minimum gas inlet may be increased if the measurement starts with a high flow rate. In this case a higher pressure is needed until the micro capillary in the base plate is clear of packing liquid.
• ⁽⁶⁾ Because of calibration factor with 2 decimals
