Automatic Meter Readers (AMR): Spot Faults and Keep Them Working for You

In today’s energy landscape, accurate data is key to managing costs and consumption. That’s why Automated Meter Reading (AMR) devices are such a valuable tool for businesses. They streamline the process of collecting energy usage data, reduce manual effort, and help ensure your invoices reflect actual consumption. However, like any technology, they can occasionally stop functioning correctly, which can result in expensive consequences for your energy bills if not caught and addressed promptly. Here, we will look at how these devices function, some of the common failure modes, and what you can do to avoid unexpected energy expenses for your business.  

How Do AMR Devices Work?

AMR devices connect to your electricity or gas meter and they use various technologies such as radio frequency, cellular networks, or wired connections, to automatically collect and transmit consumption data to your energy supplier at regular intervals. This automation helps to avoid estimated billing, which can be inaccurate. It is important to note that the communication only works in one direction - so your supplier cannot request a reading from your device remotely.

What Can Go Wrong? Common AMR Faults:

While AMR devices are generally reliable, faults can occur. The most common error modes include:

• Flatlining: The device stops updating readings and reports the same value repeatedly, often due to a communication failure or internal fault.
• Data Dropouts: Intermittent gaps in readings normally caused by poor signal strength or hardware issues.
• Out-of-sync Data: The device can fall out of sync with the meter consumption leading to errors in the data, this might result in the AMR under recording or over recording.
• Battery Failure: In battery-powered AMRs, low battery can cause the device to stop transmitting data.

These issues can result in inaccurate billing or missed usage data, which will then show up as inconsistent with the records kept by the energy supplier on their end.

Why You Should Check Your Readings and Invoices:

Even with automated systems, it’s important to regularly check your meter readings and invoices. If your usage data seems inconsistent, and particularly if your bills are unusually low, it could be a sign that your AMR device isn’t working properly.

Remember: if energy is being consumed but not recorded or billed due to a fault, this does not prevent you from still being liable for such consumption. That’s why proactive monitoring is essential.

There are a few things that you can do to keep on top of your energy consumption and avoid any surprises:

Compare Usage:

• Does the billed consumption match your expectations based on operational activity?
• Are there sudden spikes or drops in usage that don't align with known changes?
• Do the readings reflect known shutdowns, maintenance periods, or seasonal changes?

Look for Flatlining:

• Are the readings the same across multiple periods despite gas being in use? This could indicate a fault.

Estimated vs. Actual Readings:

• Is your bill based on actual readings or estimates? Frequent estimates may signal a communication issue.

Flag Anything Unusual:

• If something doesn't look right, don't ignore it; reach out to your supplier.
