The WattNode® Pulse meter is a true RMS AC watt-hour transducer with pulse output (solid state relay closure) proportional to kWh consumed or produced. The WattNode Pulse meter provides 0.5% accurate kWh measurements at low cost to meet your needs for sub-metering, net-metering, energy management, and performance contracting applications. The WattNode pulse family measures 1, 2, or 3 phases in 2, 3, or 4 wire configurations. With voltage ratings from 120 to 600 Vac and current transformer (CT) ratings from 5 to 6000 amps, there is a meter and CT combination to measure all types of electrical services.

Measurements

  • Net Real Energy: kilowatt-hours - kWh (Phase A, B, C, sum of all phases)
  • Positive Real Energy: kilowatt-hours (sum of all phases)
  • Bidirectional Real Power: Watts (Phase A, B, C, and sum of all phases)
  • Reactive Power: VARs (Phase A, B, C, and sum of all phases)
  • Power Factor: PF (Phase A, B, C, all phases)
  • Reactive Energy: kVAR-hours (All Phases)
  • AC Frequency
  • RMS Voltage: (Phase A, B, C)
