The Rotary Meter Series is designed to accurately and reliably meet the highest demands of gas flow measurement. Meters are MID approved and fully comply with ANSI B109.3 and OIML R137. The compact exchangeable aluminum cartridge allows local repair and on-site cleaning. The robust design of the casing and cartridge make the meter less sensitive to installation stresses caused by the connecting piping. The entire aluminum casing is designed for working pressures up to 290 psig with a safety factor of 4.

Meters are more resistant to overload and pressure shocks because of the improved
position of the main bearings and shafts and square impellers. The aluminum index and the protection of the standard installed, low frequency reed contact with the associated magnets, make the meter more resistant to tampering or manipulation.
