The Series WMT2 Multi-Jet Water Meter with Pulsed Output is a series of mechanical, water totalizing meters that display the total water usage in gallons or

and provide a reed switch output proportional to ow rate. They are available in a

range of body sizes and include NPT or BSPT couplings.

FEATURES/BENEFITS

• Multi-jet design allows for simplicity and accuracy with wide 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, even under harsh conditions

• Integral strainer that protects meter from particulate damage

• Easy installation with included coupling adapters

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

APPLICATIONS

• Irrigation

• Cooling systems

• Filtration systems

• Water monitoring
