Internet Enabled Energy Meter Specifications
Our Web Enabled Meter is a revenue grade meter (class 0.2) that integrates a highly accurate electric metering and measurement IC and a sophisticated network module which enables an Internet based advanced metering solution. Our IP enabled electric meter uses the latest technology to deliver unrivaled benefits. Our meters are calibrated using the RFL 5800 which is certified to NIST standards and is calibrated periodically to ensure the highest accuracy of our meters. Our web enabled meter is also UL Listed for both USA and Canada.

Internet Features
This smart electric meter has been designed to work over any Internet, LAN or WAN connection. Using any Internet browser, users have instant access to the advanced features of this IP electric meter through its built-in web server.

Any ethernet connection will work with the electric meter. Network firewall restrictions that too often limit Internet devices are easily overcome using the email / ftp client built into the electric meter's software. Sometimes providing a dedicated external IP address is not possible. This may prevent access to its web server from outside the local network. In such a case, the IP electric meter can be setup to periodically send email reports and/or update load profile data to any ftp server. Communicating with multiple IP electric meters is as simple as connecting them to a tcp/ip network.

ANSI Compliant		Open Protocols
Revenue grade energy meter is accurate to within 0.2%		Our goal at Energy Tracking is to facilitate open access to meter data without the need for proprietary protocols.
ANSI C 12.20		Ready for Future Enhancements
		The advanced electric meter's firmware can be upgraded to implement new features via ftp.
Measurement Features
This advanced electric meter incorporates all of the power measurements one would expect in an advanced solid state energy meter.
This versatile four quadrant electric meter measures phase voltage, amps, frequency, true power, reactive power, apparent power and power factor. In addition, peak demand and summation data supports typical time-of-use tariff. This meter accepts external CT's with a 5 Amp secondary. Note: Voltage ratings are line-to-line.
