by Shane Henson — July 2, 2012—E-Mon, an electric submetering market company and manufacturer of the E-Mon D-Mon product line, has announced the availability of a new interval data recorder (IDR) for collecting kilowatt-hour and demand data from up to 8 or 16 connected meters at user-selectable 15, 30 or 60-minute intervals.
The IDR provides a host of benefits at an affordable price, notes the company. A new four-line liquid crystal display (LCD) shows real-time data, while onboard memory stores up to 72 days of 15-minute interval data accessible via modem, Ethernet, Modbus, BACnet, LonWorks TP or MV-90 for automatic meter reading, energy management integration, billing and more.
Available in two basic models, the eight-meter (IDR-8) and the 16-meter (IDR-16) both offer simultaneous dual-protocol communications for integration with multiple building automation systems (BAS), billing packages or measurement and verification (M&V) reporting.
“This capability enables one IDR to talk to two systems at the same time over industry-standard protocols,” explains Don Millstein, E-Mon president and CEO.
In addition to dual-protocol capability, the IDRs offer an optional screw terminal feature that allows users to gather and store data from third-party pulse-output devices such as electric, gas, water, BTU or steam meters. Now all energy data can be read, reported and analyzed through one point, the company says.
Unlike submeters, which continuously read energy usage as it occurs, IDRs collect and store meter information at specified time periods, storing the data for later download to E-Mon Energy or other software for load profiling and more detailed comparative analysis or billing. E-Mon says the highly flexible IDR provides a number of communication media options, including Modbus RTU or TCP/IP, BACnet MS/TP or TCP/IP, or LonWorks TP.
