GridMax Meters are single and poly phase electronic watt hour meters that are designed to offer high quality, reading, performance and two way communications at an affordable price.

GridMax Meters send power quality data such as voltage, current, averages, peaks, sags and other information that is needed for TOU, CPP and RTP pricing to GridMax backhaul or other data collection systems.

To insure system security and confidentiality of data GridMax Meters use strong PKI (Public Key Infrastructure) based security for identification and encryption of data that is sent over the network.

Two-way, near real time communications network to support
Advanced Metering Infrastructure (AMI), Demand Response (DR) and Distribution
Automation (DA)
Supports residential (single phase)
Self-initiating and self-healing network
Highly secure network (PKI) to safeguard against cyber attacks and physical tampering
Security features built into key points within the network including end devices, communications system, gatekeepers and network server

GridMax meters provide the accuracy and reliability needed in different deployment environments. They are available in different form factors from the standard ANSI certified meters to custom indoor/outdoor meters.

GridMax Meters are built for the Smart Grid and feature communication protocol technology that can be configured to utility customer requirements. This includes RF, ZigBee, GPRS, Wifi, RS485 and PLC.

GridMax Meters provide network level security using state of the art encryption and latest digital certificate technology to ensure data communicated is both secure and tamper proof.

PERI ANSI electric meters with optional disconnect relays
PERI's ANSI meters are secure, accurate, robust and reliable energy meters solution for advanced metering infrastructure solutions (AMI). PERI's highly secure wireless communication establishes a two way communication with the meter and the meters form a mesh topology. The meters can be accessed and controlled remotely. The mesh network formed by the gateway and meters are self-healing and discovery for network stability.

FEATURES
Wireless Communication
Every meter comes with built-in PERI's ZigBee communication module which offers high security communication. Using digital certificates and industry standard encryption, each meter securely connects to the utility network by forming a self healing ZigBee mesh network.
