Dwyer Series WMH Multi-Jet Hot Water Meter

The Dwyer Series WMH High Temperature Multi-Jet Water Meters are a series of mechanical, water totalizing meters that display the total water usage in gallons with m3 options. They are available in a range of body sizes and include NPT or BSPT optional couplings. The high-temperature resistant brass body is compatible in applications with high-temperature water no suitable with standard brass water meters and maintains its accuracy.
Product Applications

  • HVAC applications
  • Measuring total condenser water flow in residential, commercial and industrial applications
  • Remote hot water monitoring
  • High temperature threshold of 190°F (88°C) ideal for high temperature applications
  • Multi-jet design allows for simplicity and accuracy with wide flow ranges, even in low flow 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 that protects meter from particulate damage
  • Easy installation with included coupling adapters
  • Pulsed output proportional to flow allows for remote flow totalization
