Measuring range for gases
Measuring ranges valid only for Promass H with tantalum 2.5W.
The full scale value depends on the density and the sound velocity of the gas used and can
be calculated with the formula below:
 = minimum (
max(G) max(F)
 Maximum full scale value for gas [kg/h]
max(G)
 Maximum full scale value for liquid [kg/h]
