Neptune Type S Meter with Magnetic Drive

  •  The 1-1/2" and 2" Type S Magnetic Drive flowmeters with double case construction utilize the nutating disc positive displacement technology.
  • This design results in an accurate meter, which is insensitive to small changes in viscosity and flow profile disturbances.
  • The magnetic drive feature eliminates the use of a drive shaft stuffing box eliminating a leak path. This enables measurement of difficult fluids such as salt brine and sugar, which tend to crystallize.
  • The Type S Magnetic Drive is an ideal selection for continuous operation because they substantially reduce leaks and measuring element clogging. Further, the external gear train and register may be serviced without flow interruption.
