Web Enabled Energy Meter for Submetering and Tracking, kWh Meter, Power Measurement, Energy Management, Load Profile, Billing

Web Enabled kWh Electric Meter:

Our Web Enabled Electric kWh Meter (WEM-MX) is revenue grade compliant to ANSI C12.1 / C12.20 (0.2% accuracy). It is Internet enabled, broadband ready smart electric meter for commercial and industrial applications. It can be deployed as a primary meter, submeter or used for other electric metering applications such as energy usage tracking, demand reduction, power factor correction, etc. Besides tracking peak demand (kW) and energy consumption (kWh), this advanced meter integrates many important features and provides enhanced functionality such as automatic outbound reporting using 100% open protocols.

Its open system design facilitates world-wide deployment to populate applications with real time data based on accurate measurements. This electric meter is designed to meet requirements for data on demand from multiple users. Traditional meters focus only on single user applications at fixed time intervals.

It is the right solution in today’s complex energy markets combining low cost, high accuracy, minimum cost of communications with real time data access and reporting.

This sophisticated web enabled meter combines elements of simplicity, is highly functional and reduces overall ownership costs. Since most facilities already have an existing network, the cost of communication is virtually nil.

It has an embedded web server that can be accessed via MS IE web browser. Please review WEM-MX Screen Shots & ET Analytics.

Load Profile And Peak Demand Capability:

This advanced kWh meter provides peak demand (kW) with a date and time stamp informing you as to when the peak demand occurred. It also has the capability to periodically record and store interval data usage (load profile) based on a user defined interval of 1 minutes to 60 minutes or more. This functionality helps identify where, when and how much energy was consumed say, every 15 minutes. It can also store energy consumption by time-of-use (TOU). This allows end users to identify how much energy was consumed during different periods of the day. Configuration settings are done via its on board web server.

This smart kWh meter can be used as a demand meter, time-of-use (TOU) meter or load profile meter - providing the right functionality for sub-metering, energy management and other metering applications such as demand reduction. Also, it boasts a wide variety of features like XML data encapsulation and broadband connectivity enabling it to transmit data via email, ftp, ModBus or Web Service client. Reports can also be accessed via its web server.

The optional supporting software applications include Enterprise Energy Tracking Analytics (ETA); a web portal cloud-based hosted solution that allows end users immediate and long term access to energy usage information and ET Real Time Mobile Application (ET-RTM) enabling an end-to-end solution from measurement to acquisition to energy management.

SubMetering Applications:

Typical applications are: Sub meter building energy usage 24X7, renewable energy sources such as solar or wind, measurement and verification projects, tenant space, production / manufacturing energy usage.


This advanced electric meter is able to send data over the Internet using file transfer protocol (ftp), email, Web Service client, MODBUS or can be accessed via its web server. Lower your metering costs by using the existing Internet connection or local area network, avoiding PSTN based networks, maintenance of telephone lines and eliminate costs for dedicated phone lines.

Load Curtailment Projects:

This smart meter is an ideal and proven product for Demand Response / Emergency Demand Reduction Programs.

Remote Meter Reading:

Automate and get fast accurate data over the Internet. The data is sent via ftp, email, web services or accessed directly from the meter's web server.
  • Better management of total energy usage.

  • Get details about the amount and timing of your energy use, so you can adjust accordingly and save money.

  • Load profile data provides 24X7 energy usage patterns.

  • Identify and implement operational strategies to control load factor, peak load requirements and reduce energy waste.

  • Understand and improve consumption patterns.

  • Measure and verify anticipated energy savings from energy efficiency modifications.

  • Highlight anomalies in electric / energy consumption. For example, a large night time increase may indicate that equipment is running unnecessarily.

  • Identify and assess on a real time basis the fiscal impact of the energy consumption.

  • Advanced notification via email of a higher peak demand being set.

  • Instantaneous real time access to measurement and metered data via the Internet or local network.

Data can be used to:

  1. Track in real time energy usage, load, power factor and when your peak demand occurs.
  2. Identify and manage peak demand to avoid high utility bills.
  3. Create benchmarks and baselines to compare variation in energy usage over time.
  4. Correlate energy usage to costs.
  5. Reduce and limit the energy costs for your business.
  6. Validate the utility bill.
  7. Perform extremely accurate forecasting for budgeting purposes.
  8. Optimize energy usage and increase dollars to the bottom line.

Real Time Data Measurement And Reporting:

Nowadays, majority of buildings have a network already present. Our meter’s connection to a network is identical to that of a PC or laptop. There are 4 ways energy usage data can be accessed.

1. Connecting to the meter’s Web Server provides immediate access to data using MS IE Web Browser.

2. Meter can be set up to send reports periodically via email.

3. Meter can be set up to send reports periodically via ftp.

4. Meter can be set up to send reports periodically via web service.

5. Meter data can be accessed via MODBUS TCP.

Acquiring data in real time from a network enabled meter has many advantages and provides significant benefits. Real-time data provides a greater understanding of the dynamic response characteristics of energy usage. Acquiring real-time data enables proactive management as after-the-fact does not help.

The most important is its ability to send frequent reports has no impact on communication costs, unlike the telephone-modem based meters. For example, load profile data can be dispatched every 1 minute.

Certain applications such as tenant billing only require once a month reporting which can also be setup in the meter, but knowing that you can generate or provide more frequent reporting has value in the sense that such reporting can prevent end of month ‘shock’ should energy usage go unexpectedly high. The meter can be setup to report to (cc:) tenants that would benefit from this.

If the meter sends an email warning of a peak demand threshold being crossed, you can take immediate action to avert this.

It is by far simpler and faster to use an Ethernet network than using a telephone dial up modem. Many corporations have an IT department and use their own software. The ability to easily interface with our meter over a network and capture data in XML or view data using a standard web browser such as MS IE provides additional value.

Energy Usage Analysis:

Using the interval logging capabilities of our meter, you can identify where, when and how much energy is used over time. You can chart and print energy consumption by months, weeks, days, hours or sub intervals.

You can identify when the highest peak demand occurred and the time at which it occurred.

You can compare energy consumption on various days to identify anomalies and review changes in operation. You can also perform kWh v/s kVARh, kW v/s kWh analysis or compare energy usage of multiple sites.
Billing Analysis:

Our ET Analytics application has a tariff module which allows you to enter energy and demand costs for weekdays, weekend and holidays. You can then generate and print a bill based on the tariff.
