min
depending on p
min
)
Connections in compliance with DIN or ANSI are available
Special designs for aggressive gases are available
Available for low temperatures (< - 20°C)
All gas meters can be operated in any position up to the nominal diameter of
DN 200.
Notice
The meters with nominal diameters from DN 50 to DN 200 are approved
for custody transfer metering (up to G 1600).
The nominal diameters from DN 250 are special versions without MID
approval for which RMG does not guarantee the availability (only on
request).
