The EG4xxx series meters are capable of monitoring up to 7 single-phase units (EG4015) or 15 single-phase units (EG4030) with a single meter. Single-phase units require 2 CTs each, one for each phase. Please visit Getting Started for an overview of the physic...

An EG4xxx Quick Start guide is included with each meter. A copy may be downloaded here.

 Visit the online store page eGauge Systems offers the 80mm AccuEnergy AcuCT-3135R revenue-grade CT in 1,000 A and 1,500 A ratings. For smaller sizes and amperage ratings, see our 20mm and 36mm High-Accuracy CT offerings which offer ANSI C12.20 0.5% accuracy ...

Custom CT size scale factor Calculation Always use caution when choosing to use unsupported CTs with the eGauge meter. Supported sensors are always preferred and will yield the most accurate results. eGauge Systems cannot guarantee accuracy or safety when usi...

This article describes using pulse sensors to read from energy meters, but any meter such as flow meters may be used. The only difference is to change the formula register from "Power [W]" to the particular measurement and using a "constant" that represents 1 ...

This article covers common physical reasons for unexpected sensor readings in the channel checker or register values including AC (RMS), DC (mean), and Frequency readings. This article applies to both CTs to measure amperage and Sensor Hub compatible sensors. ...
