Avoiding the need for direct connection via copper wire between an electricity meter’s KYZ pulse initiator and the energy management system or other telemetry equipment, the PRL-900 Pulse Radio Link system introduced by Solid State Instruments makes a reliable wireless connection to a receiver located up to 1000 feet (300 metres) away. This eliminates the need for trenching or stringing overhead wires.
The PRL-900 operates in the 900 MHz band, creating a pulse identical in width and frequency to that seen at input. Signals from the weather-resistant transmitter are redundant and verified before transmission, ensuring that both energy consumption and energy demand information are accurately transmitted. The system’s receiver additionally contains a software algorithm designed to ensure integrity of the data before output.
