SERIES WPTN | MULTI-JET NSF CERTIFIED PLASTIC WATER METER

FEATURES/BENEFITS

• Plastic, NSF certied body is ideal for potable water applications

• Multi-jet design allows for accuracy in various ow ranges, even in low ow applications

• Magnetically driven, hermetically sealed register does not leak or fog and is completely separated from the water

• Designed for long service life and maintenance-free operation

• Integral strainer protects meter from particulate damage

• Included coupling adapters simplify installation

• Pulsed output proportional to ow allows for remote ow totalization

APPLICATIONS

• Potable water

• Commercial water usage

• Chiller water usage

• Low cost residential water measurement

• Agriculture (fertilizers, pesticides, and herbicides)

• Irrigation

• Remote water monitoring

DESCRIPTION

The Series WPTN Multi-Jet NSF Certied Plastic Water Meter is a

series of plastic mechanical water totalizing meters with NSF certication. The meters display the total water usage in gallons. They are available in a range of body sizes and include NPT optional couplings. The plastic body water meters can be used where standard brass is not compatible, in potable water applications, some corrosive environments, or where an economical water totalizer is desired.
