Water flows through the meter's strainer and into the measuring Maintenance
chamber where it causes the disc to nutate. The disc, which moves Badger Meter Recordall Disc meters are designed and manufactured
freely, nutates on its own ball, guided by a thrust roller. A drive to provide long -term service with minimal maintenance. When
magnet transmits the motion of the disc to a follower magnet maintenance is required, it can be performed easily either at
