Continental Control Systems has announced a new line of electric power meters, the WattNode Revenue. These meters are designed for use in applications requiring revenue-grade accuracy. The WattNode Revenue meters meet the accuracy requirements of ANSI C12.1 and C12.20 Class 0.5, and support Modbus, BACnet, or LonTalk communications protocol or a pulse output.
We are excited to offer our customers meters that meet and exceed the ANSI C12.20 Class 0.5 accuracy requirements. Achieving this goal required a significant engineering effort to improve our meters, current transformers, and calibration systems. Nathaniel Crutcher, Director of Engineering, Continental Control Systems
The WattNode Revenue marks a new level of performance for the WattNode brand of electric power meters. WattNode meters are used in building automation and energy management systems world-wide and offer a compact, cost-effective, networkable solution for electric power metering. The new WattNode Revenue now brings these same advantages to revenue-grade applications.
The WattNode Revenue electric power meters are optimized for tenant submetering in residential and commercial spaces, PV energy generation metering, UMCS metering on military bases, and more. The ANSI C12.1 and C12.20 standards require CTs which meet IEEE C57.13 accuracy, such as the Accu-CT® line of current transformers. The WattNode Revenue meters are designed for 120/208/240 Vac and 277/480 Vac applications.
Each meter is calibrated using NIST-traceable equipment following the procedures specified by ANSI C12 metering standards, and is supplied with a certificate of calibration. In addition to revenue-grade, bidirectional energy (kWh) metering, the networkable WattNode Revenue meters provide dozens of additional measurements: bidirectional power, demand, peak demand, reactive power, voltage, current, power factor and line frequency.
The WattNode Revenue Logger for LonWorks can store 12 weeks of five-minute readings. The WattNode Revenue meters will make their debut at WEEC 2012 in Atlanta, and will also be on display at the 2012 Greenbuild International Expo in San Francisco.
