• Unrestricted Mounting: Allows for horizontal, vertical or inverted installation and does not require straight plumbing on inlet or outlet.
  • Superior Exterior Design: Weather-tight for use outdoors and/or on systems where wash-downs are required.
  • Rugged and Reliable: These meters are constructed with all metal pressure vessels that allow safe and permanent installation.
  • Multiple Ports Available: Standard selection of NPT, SAE and BSPP ports reduces the amount of adapters required for installation.
