Elster Metering is the new group formed from the acquisition by Ruhrgas Industries of ABB`s global metering business. Elster Metering is a market leader in electricity and water metering. LINExpert - automated meter reading system power line carrier - offers a very pragmatic and cost-efficient approach of the automated meter reading for single phase and poly-phase meters. The electricity meter is installed in the low voltage grid and periodically transmits its kWh reading on the power line. The technique used has been initially h the military and is well known for its reliability and noise immunity. The data concentrator - EMgate is installed in the low voltage grid, collects the kWh readings from the ed meters, stores the hourly load profile data and sends it further towards the customer`s LAN through radio, GSM.GPRS or via direct serial link for analysis, billing or theft detection. The salient features of the system are works in the low voltage grid; one way kWh reading on power lines in the 50 kHz ? 8 kHz band; distances of up to 1,000metres on power line depending on the load; scheduled/manual data acquisition: arms/forecasting; hourly/daily load profile and energy consumption per customer/group of customers; line losses/ tariff analysis; primary data for existing billing systems; primary data for existing billing systems; and very low operating and maintenance cost.
