NWM PPD is Positive Displacement (Volumetric), Rotating Piston design water meter with Super Dry Type Register from size 5/8X1/2” to 2” designed by NWM and meets to AWWA C700.

OPERATION:
Water flows through the meter’s strainer and into the measuring chamber where it drives the piston. The hydro dynamically balanced piston rotates guided by a division plate. A driving magnet transmits the movement of the piston to a driven magnet located within the hermetically sealed register. The magnet is connected to  a  gear  train  which  translates  the  piston  rotates  into  volume  totalizators
displayed on the register dial face.
