Wireless Meter Pulse Generator

WPG-1

The SSI WPG-1 Wireless Meter Pulse Generator is our wireless Pulse Link to the ITRON Gen5/Riva meter, integrating advanced AMI smart meter technology with legacy KYZ pulse metering. Using a Wi-Fi interface, the WPG-1 receives usage data from the meter, interprets power usage, and converts it into KYZ pulses — without requiring a physical KYZ output at the meter. This allows utilities to deploy the latest AMI meters while continuing to provide pulse outputs to customers who depend on them.

The WPG-1 incorporates a Wi-Fi radio module and two independent KYZ pulse outputs. Each output is individually configurable for pulse type (kWh, kVAh, or kVARh) and value, in either delivered or received quantities. All settings are managed through a USB programming port using the SSI Universal Programmer software.

Product Highlights

The WPG-1’s two independently configurable outputs offer flexibility for complex metering applications — one output can be set for delivered kWh while the other monitors kVARh received, for example — all from a single device. Output pulse values are selectable from 1 to 99,999 Wh, VAh, or VARh per pulse, with a meter multiplier of 1 to 99,999.

LED indicators provide immediate visual confirmation of both pulse output status and Wi-Fi communications health without the need for additional test equipment. A 30mS fixed minimum-off time delay ensures reliable, clean pulse output. For installations requiring weatherproof outdoor housing, the WPG-1E and WPG-1SC variants offer NEMA 4X enclosure options.

Features

The WPG-1 integrates AMI smart meter technology with legacy KYZ pulse metering.
  • Wi-Fi Interface Input — connects directly to ITRON Gen5/Riva meter's Wi-Fi interface; no hardwired KYZ output required.
  • Two Independent KYZ Outputs — dual Form A (2-Wire) or Form C (3-Wire) solid-state outputs, each independently set for type and value.
  • kWh, kVAh, and kVARh Support — each output configurable for energy, apparent, or reactive power pulses in delivered or received quantities.
  • USB Programmability — pulse type, value, multiplier, mode, and timing all set via the free SSI Universal Programmer software.
  • Selectable Output Modes — momentary mode with six pulse width options (25–1000mS) or toggle mode emulating classic KYZ output.
  • LED Status Indicators — four LEDs (two red, two green) display individual pulse output status plus communications health at a glance.
