Energy Metering Essentials: The Data Logger

It’s time to refresh our knowledge about hardware in energy efficiency projects! What could be better than a free training on such an essential piece of the energy metering puzzle…

You got it, we’re talking about dataloggers! Read on for details about the live training and Q&A session.

What is a Data Logger?

Good question, because you might have heard of gateways instead of data loggers, which are also known as dataloggers or data recorders. So many names for the same piece of hardware!

Data loggers are the Internet experts of energy meters. It’s basically a cheap and smart piece that connects your meters with the world outside your building.

Most meters, such as a water fiscal meter for example, cannot send data to the Internet, or to other systems like BMS (learn more about these here).

A data logger is the “middleman” piece that is integrated into your building’s MODBUS network, gathering all readings from all meters in the facility and sending this aggregated data to the Internet.

Using a data logger means you can get your analysis with DEXMA Energy Intelligence Platform up and running in just a few hours. If you’re curious about how to set one up, check this article.

What is the value of a data logger?

This is one of the key questions we will answer in our upcoming training about hardware, but not the only one.

In short, these little devices:

  • Save a lot of setup time on facilities. Just picture it: one single piece speaks with all the other meters. One piece to install, and you’re connected.
  • Data loggers are money savers, especially if you choose an open data logger, which is more likely to be integrated with as many devices as possible.


What should I look for in a data logger?

In our webinar we will use DEXGate2, our flexible data logger, to give you examples of desired features you should check for when purchasing your next data logger.

Here are two that are pretty key:

  • First, an open approach. Look for a data logger that can integrate with as many energy meters and submeters as possible.
  • Second, price is an important decision making point when talking about data loggers. You’ll need a flexible and robust piece of hardware, yet it shouldn’t be super expensive, otherwise it will increase overall hardware costs instead of decreasing them.

As mentioned, we will review more interesting data logger features in our free online training on April 27th.
