Monitor Electricity on Every Circuit with Precision and Accuracy

Better than a kWh Meter

The eGauge is a CT meter, which means it can measure the power of individual circuits in your electric panel using sensors called current transformers (CTs). The meter also displays your energy data on a webpage in real-time. Watch as your graph changes every second, revealing potential problems that you could never discover with a simple utility bill.

Mobile Energy Alerts

Carry on with your daily routine while eGauge watches for unexpected energy patterns. These text and email alerts work for you to find excess equipment usage, unexpected demand charges, loss of renewable energy production and other costly failures. Energy alerts are user-definable and can be set to trigger for virtually any threshold value.

Greater Efficiency Savings

Save more money with your energy efficiency projects with a metering system that has no subscription fees. We want you to take two steps forward and no steps back when it comes to your green investments.

The eGauge Hardware

Meter | Data Logger | Server

Each eGauge unit combines an energy meter, data logger, and a web server. This powerful combination lets you measure, store and retrieve data directly from the device or from a remote location. Not only does it calculate power (V, A, VAr, kWh, etc), but also data from optional sensors that assess flow rate, temperature, wind speed, and more. You can view historical and live data for up to 30 years with the unit’s convenient user interface (UI). The UI can be accessed on a local network or via the internet from a computer, tablet, or smartphone. Once connected, you have access to real-time values, long-term reports, an interactive graphical interface, and many other tools. The best part is that you pay nothing for the user interface because you retrieve data directly from your own eGauge hardware, not a cloud or 3rd party host.

User Interface

Data | Graphics | Alerts

The eGauge UI presents a powerful and straightforward graph to visualize energy data. The graphical view is highly customizable and can be set to display (or hide) any number of monitoring points. The monitoring points are shown with user defined time periods so it's easy to analyze data ranging from minutes to months, or even years. Users can create custom views which present data that is formatted for a particular need and removes irrelevant information. The graph is a staple of the UI because it can present highly granular data in an understandable way.

3 Tips For a Successful CT Meter Installation

A CT meter is a device that measures amperage in one or more conductors using sensors called current transformers (CTs). Current transformers come in many sizes and amperage ratings which allows a single meter to measure all kinds of electrical loads. In addition to amperage, these metering devices measure voltage so they can ultimately calculate power.

What is Power Factor?

Power factor is the ratio of real power (kW) to apparent power (KVA). This ratio can be a value from 0 to 1, and it indicates how efficiently an AC circuit is using electricity, with a value of 1 representing high efficiency. The third type of power, called reactive power (KVAr), causes electronics to be inefficient and draws the ratio closer to 0 by creating a difference between real power and apparent power.
