Multi-Customer or Multi-Load Metering Made Easy!


The i-meter® 636 is a Multi-Customer Metering System. Capable of metering up to 16 single elements the compact design is great for applications where Tenant or Energy Cost allocation is important. The i-meter® 636 provides critical KwH as well as the ability to monitor Volts, Amps, KiloWatts, Power Factor, and Frequency (V, I, kW, kVA, PF, Hz).

  • Innovative Metering Solution
  • Approved by Measurement Canada and meets ANSI revenue standards
  • Multi-Customer Metering System can be integrated or embedded into any Distribution Panel
  • Optional data display can be mounted in a utility room or management office
  • Support Building Automation Systems in Modbus, BacNet, RF or TCP/IP
  • Compact design usually installs right next to the breakers can save valuable installation time.
  • The i-meter® 636 works as a 16 single-element, 8 2-elment or 5 3-element meter
  • Applications: Residential, Commercial, Industrial
