Energy Meters And Measurement Sensor

What does an energy meter do?

An energy meter measures the amount of electricity consumed in a building. Since they have become digital thanks to technological advances, they are even more accurate than before (when they were simply electromechanical). The smart energy meter makes it possible to identify peaks in consumption and gain a better understanding of energy habits.

Thanks to your meter, you can :

• understand your consumption habits
• identify the equipment that consumes the most energy
• and soreduce your costs and your energy footprint.

This product was originally designed to bill users for their consumption, but it has evolved into a genuine diagnostic tool, useful in all areas, from residential to industrial and tertiary.

How do you read and interpret your energy meter?

Reading an electricity meter may seem technical, but it's a simple operation given the right indications.

• On the main screen, the consumption index is displayed in kilowatt-hours (kWh).
• Use the button to navigate between the data: total consumption, peak and off-peak consumption, if applicable.

You should also be aware that there are connected smart meters (such as ref A9MEM3250). Their advantage is that you can easily access your data via an online application or portal. This allows you to monitor consumption in real time and optimise your usage.

How do you choose your energy meter?

Choosing the right energy meter is essential to optimising the management of your electricity consumption. Here are the criteria to consider:

• Number of feeders: For a single circuit or several (multi-tariff).
• Type of network: Single-phase (P+N) or three-phase (3P+N).
• Connection: Direct, with integrated CT, or via an external transformer.
• Rating: e.g. up to 125 A (iEM3000) or 3200 A with transformers.
• Communication: Protocols such as Modbus, M-Bus, or BACnet for advanced supervision.
• Compliance: IEC or MID certified models for chargeback.

Our key Schneider Electric meter references

Reference Schneider A9MEM2455

This single-phase meter accurately measures active and reactive energy up to 100 A (class 1). Modbus RTU compatible, it is ideal for residential or tertiary installations requiring simple and reliable monitoring and is perfectly suited to sub-billing and cost allocation applications.

Reference Schneider A9MEM3110

Suitable for three-phase installations up to 63 A, this meter offers great flexibility thanks to its multiple protocols (Modbus, BACnet, M-Bus). It is perfect for commercial or industrial environments.

Reference Schneider A9MEM3250 - connected

Designed for large infrastructures, this model measures up to 3200 A using external transformers. With its 0.5S accuracy class, it is perfect for large industries or renewable energy installations requiring maximum reliability.

Energy meter applications

Schneider energy meters are suitable for a wide range of applications. For sub-metering, they can be used to distribute consumption in the tertiary and industrial sectors, while guaranteeing accurate readings.

They are also a key tool for RE2020 energy management, making it easier to manage consumption by use (heating, lighting, etc.). For environments requiring MID-certified rebilling, such as shopping centres or shared spaces, these meters are an ideal solution.

Our radio-frequency measurement sensors

Powertag sensors are advanced solutions for measuring energy consumption in real time, connected to an Ethernet interface. Designed primarily for the tertiary and industrial sectors, these sensors enable precise, optimised management of energy consumption.

Why choose a Powertag sensor?

Powertag sensors have a number of advantages:

• Simple installation: Easy to fit to different types of circuit breaker, such as NSX, iC60, iDT40.
• Radio-frequency transmission: Data is sent to PowerTag Link concentrators via radio-frequency, guaranteeing reliable wireless connectivity.
• Accurate and cost-saving: They provide accurate measurements for more efficient energy management and substantial cost savings.
• Wide range: A choice of models to suit a variety of installations, from 16A circuits to complex installations up to 2000A.
