WebMeter48™ E-Series

The WebMeter48E™ is the next generation of affordable intelligent metering for your energy network. The fully enclosed meter is designed to accept voltage and amperage data from single, poly or three phase circuits. Pulse data from third party meters e.g. water, gas, steam, BTU, can be connected using the CircuitMeter JPulse-4™.

The WebMeter48E™ accommodates any combination of up to 48 current transformers or pulse inputs to capture granular electrical and non-electrical information. Sampling rates up to 200,000 samples/second, the WebMeter48E™ delivers accuracy at the circuit-level and reports the information every 2 seconds to the CircuitMonitoring™ system providing a full spectrum of real time data.

The WebMeter48E™ is a complete energy management metering solution allowing for widespread granular metering for industrial, commercial, institutional and multi-residential installations. At a dramatically lower cost per circuit with easy installation, the WebMeter48E™ is designed for economic deployment across a portfolio of facilities while metering at the individual circuit and equipment level.
