Langhorne, PA, U.S.A. --- (METERING.COM) --- December 2, 2011 -  Four new smart meter class devices, offering built-in communications, advanced energy information — including 38 metering parameters — and expanded communications functions, have been introduced by electric submetering manufacturer E-Mon.

In addition to recently completing requirements for UL/CUL listing, the meters also have been certified as meeting ANSI C12.20.

Three of the meters — the Class 3400, 5000 and Green Class Net Meter — offer simultaneous dual protocol communications for integration with multiple building automation systems, billing packages or M&V reporting.

“This capability enables one meter to talk to two systems at the same time over industry-standard protocols,” said Don Millstein, president and CEO. “This greatly enhances the value of any meter investment by allowing the user to obtain granular meter data from a single device acting as a separate billing meter and also as an independent building automation system (BAS) meter.”

To further facilitate cost effective operation, the meters offer reduced-cost BAS protocol options.

The individual features of each new meter include:

  • Class 3200 — available in a multiple meter unit (MMU) version, the Class 3200 offers a 4-line LCD showing kWh, demand with peak date and time, power factor per phase, real time load in kW, Amps per phase and more. Meters include built-in RS-485 communications and come standard with EZ7 protocol for use with E-Mon Energy software. The meters are optionally available with Modbus RTU and BACnet MS/TP protocols.
  • Class 5000 — offers all features of the Class 3200 does, including dual protocol functionality, Ethernet and more in a standalone, non-MMU configuration. The dual-protocol output allows operation for RS-485 and Ethernet communications simultaneously, along with independent communication with E-Mon’s automated meter reading (AMR) systems and the BAS or other front-end monitoring system. Communication media choices include Modbus RTU, Modbus TCP/IP, BACnet MS/TP, BACnet IP or Lon-Works (TP).
  • Class 3400 — offers all features of the Class 5000, but comes in a larger 6” x 8” enclosure equipped with a larger 4-line LCD display and is available with an optional expanded feature package that includes built-in functions for load control and two pulse outputs (one kWh and one kVARh).
  • Green Class Net Meter — designed for applications requiring collection of net data, this meter provides the same feature set as the Class 5000 but adds kWh delivered, received and net kWh. It also includes dual protocol functionality, Ethernet, pulse inputs and phase loss alarming in a standalone, non-MMU configuration.
