WM2
The Series WM2 Multi-Jet Water Meter is a series of mechanical, water totalizing
meters that display the total water usage in gallons or m3. They are available in a
range of body sizes and include NPT or BSPT couplings. 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 m3 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.
BENEFITS/FEATURES
• 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
APPLICATIONS
• Irrigation
• Cooling systems
• Filtration systems
• Water monitoring
