A bold value indicates that the maximum flow is limited by the maximum Reynolds number value of 1 200 which is reached
before the normal differential pressure range is reached. In that case, the second value gives the minimum flow for which
measurement uncertainty (accuracy) is equal to the nominal uncertainty specification. Divide the second value by 10 when
using molbox RFM microrange option.
Where there is no value in the field (–), this indicates that the maximum Reynolds number is reached before the differential
pressure reaches 5 kPa (1 kPa in the case of the 1E5 molbloc), therefore calibration with that gas is not useful.
1 Due to low vapor pressure, only downstream calibration type is available.
2 The operating pressure range is greater than the vapor pressure value for this gas.
