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. The remaining error is less than approx. ±1% across the full flow rate range. = approximate value, may vary due to manufacturing tolerances
2) approximate value, can deviate due to production tolerances
3) = volume of measuring chamber
4) Because of calibration factor with 2 decimals
5) Higher gas inlet pressure until gas inlet channel and micro capillary in the base plate are clear of packing liquid
6) 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.
