Why Sub-Metering Is the First Step to Energy Savings

Sub-Metering Is the First Step to Energy Savings

You can’t start reducing energy until you know where you’re wasting it. Do you know how much energy it takes to heat that furnace? How efficient is that transformer? Without accurate data, energy-saving initiatives are guesswork.

Why Sub-Metering Matters

Most industrial sites rely on a single main meter. That tells you your total consumption—but not where it’s happening. Sub-metering breaks down usage by process, machine, or area, giving you actionable insights:

• Identify energy-hungry equipment.
• Spot inefficiencies in heating, cooling, and compressed air systems.
• Benchmark performance and track improvements.

LoRaWAN Energy Meters: A Powerful Tool

LoRaWAN energy meters provide wireless, long-range monitoring without costly cabling. They’re ideal for large industrial sites because:

• Low power, long range: Sensors can transmit through steel structures and across wide areas.
• Easy retrofit: Clamp-on CTs or pulse readers mean no downtime.
• Real-time visibility: Data flows to dashboards for analysis and alerts.

But LoRaWAN Isn’t the Only Option

LoRaWAN is one tool in the toolbox. Many sites already have metering systems in place. That’s why our gateways support:

• Modbus: For integration with existing wired meters and PLCs.
• Pulse counting: To capture data from legacy meters.

This flexibility means you can combine LoRaWAN sensors with your current infrastructure, creating a unified energy monitoring system without starting from scratch.

What Can You Measure?

• Furnace energy use: Understand true heating costs.
• Transformer efficiency: Track load and losses.
• Compressed air systems: Calculate kWh per Nm³ and identify leaks.

The Payoff

Once you know where energy is going, you can:

• Optimize setpoints and schedules.
• Repair leaks and eliminate idle loads.
• Improve power factor and transformer loading.

Typical savings range from 10% to 40%, depending on the site.
