p = 1 bar; means atmospheric pressure

MR = Measuring range = Q
max
/ Q
min
[3]
MR: 1:20; for
p ≥ 3 bar(g)
To get the Q
min
, the high pressure value for defined values of the operating pres-
sure and for other gas types you can calculate it using the formula in chapter 1.8.1
Extension of the measuring range or you can contact the RMG service.
