Smart metering: What it is and why it matters

In today’s digital world, the way we monitor and manage energy consumption is evolving fast. Smart metering provides real-time insights into electricity, gas, and water usage, helping both consumers and service providers optimize energy management. But what exactly is smart metering? How does it work? And how can converters (also known as transmitters) transform your existing meters into smart devices – without the need for costly replacements?

How smart metering works

A smart metering system relies on a few key components. A meter, for measuring electricity, gas, or water usage, wireless communication network, using LoRaWAN or NB-IoT technologies to transmit data securely, data management system for collection, storage, and analysis of consumption data. And a converter (transmitter) for reading data from one or multiple meters and sending it to the central system.

The three steps of smart metering

Data collection

Meters continuously record usage, and a converter captures this data at regular intervals (e.g., every 15 minutes), offering a detailed overview of consumption.

Data transmission

The converter sends the collected data through a wireless network. This can happen in almost real-time or on a preset schedule using:

  • LoRaWAN – Long-range, low-power data transmission.
  • NB-IoT – Cellular-based transmission via a SIM card for remote monitoring.
Data management & analysis

Once received, the data is securely stored and analyzed, enabling:

  • Instant access to almost real-time consumption insights.
  • Accurate billing based on actual usage.
  • Better grid optimization by balancing supply and demand.
  • Early detection of irregular consumption or system issues.

Benefits of smart metering

Smart metering provides huge advantages for both consumers and utility providers. Smart metering enhances electricity distribution by helping utility companies optimize energy flow, incorporate renewable sources, and manage peak demand. For gas, it provides precise consumption tracking and includes advanced safety features like leak detection. In water management, it allows early leak detection, preventing unnecessary waste.

Benefits for consumers
  • No more estimated bills – Pay only for what you actually use.
  • Real-time consumption tracking – Helps you manage and reduce energy costs.
  • Automated alerts – Detects issues like water leaks or gas leaks early.
  • Faster customer support – Problems can be identified and resolved remotely.
  • Convenience – No need for manual meter readings.
Benefits for utility providers
  • Lower operational costs – Automated readings reduce labor costs and human errors.
  • Improved grid management – Real-time data helps balance supply and demand.
  • Fraud prevention – Unauthorized energy use is detected quickly.
  • Regulatory compliance – Helps meet sustainability and environmental requirements (EED, ESG).

Retrofit your existing meters with converters

Not all meters are smart, but that doesn’t mean you need to replace them. Converters (transmitters) retrofit traditional meters, enabling remote monitoring and smart capabilities.

Features of converters:
  • Works with multiple meter types – Compatible with electricity, gas, and water meters supporting M-Bus or wireless M-Bus.
  • Wireless data transmission – Uses NB-IoT and LoRaWAN for real-time updates.
  • Fast data reporting – Readings as often as every 15 minutes.
  • Quick and easy installation – No major downtime or replacements needed.

Smart metering is transforming the way we manage energy, giving consumers more control while allowing utility providers to streamline operations and improve efficiency.
