Zug, Switzerland, September 30, 2010 — Energy management solution firm Landis+Gyr, has delivered its 10,000th SyM2 meter.
The development comes as conversion of meter parks to the new industry standard for industrial and commercial customers is continuing to gather pace.
Landis+Gyr developed the SyM2 standard in close coordination with the German utilities RWE, EnBW and E.ON Energie, and was first to bring an SyM2-compliant meter to the German market at the end of 2009 with the E750 product family.
“The SyM2 concept has been very well received by energy providers”, confirms Peter Heuell, CEO of Landis+Gyr Germany. “As our sales figures show — and not to mention the number of incoming orders — the conversion of meter parks is already well underway. From the initial concept sketch to the project’s completion, the SyM2 standard and our E750 product family have focused on the practical requirements of industrial and commercial customers.”
The aim of SyM2 is to standardize meter parks for special contract customers. The heterogeneity of industrial meters has seen operating costs for energy providers soar in recent years. Currently, meter parks have a large number of different models, installed, operated, connected and read differently.
This pushes costs up as technicians must be trained to use each individual meter type and several different installation processes, and a significant number of device drivers need to be integrated. Enormous process synergies will be achieved in future — from calibration to installation, reading and maintenance — thanks to standardization.
The project to develop an open and interoperable industrial standard for special contract customers was launched jointly with RWE, EnBW and E.ON. As one of the global meter manufacturers, Landis+Gyr was charged with the task of translating the idea into reality.
In close cooperation with energy suppliers, two years of development led to the birth of the SyM2 concept. The Landis+Gyr E750 — the first SyM2-compliant meter — was finally put into batch production at the end of 2009.
Modular assembly of the new industrial meters was key, in addition to interoperability. This means that the only components used are those which are actually required — unnecessary costs and needless potential sources of error are avoided.
The required modules cannot only be assembled flexibly, but can also be replaced at any time, or new modules can be added.
Rapidly evolving components such as communication units can be replaced in a matter of minutes during ongoing use. Even counters and modules from different manufacturers can be combined thanks to open specifications.
Using communication technology, reading time will fall significantly in the future; the E750 meter transmits measurements directly to the specified server over GPRS or a LAN/DSL modem. This shift from “Pull” to “Push” operation will optimize the reading process.
The new standard scores highly for systematic cost efficiency in calibration as well as in installation. Using spring-type terminals instead of screws, SyM2-compliant meters such as the E750 can be installed easily, safely and with considerably lower risk of electrocution. Furthermore, the time expenditure for calibration can be reduced by up to 60 percent (from seven to two-and-a-half hours).
