Wired M-Bus – Precision Data for Complex Installations

‍

Overview

Wired M-Bus follows the EN 13757-2/3 standards and uses a simple two-wire bus for reliable and long-distance communication between meters and central data systems. It is ideal for multi- unit buildings and fixed installations where signal reliability and security are essential.

‍

‍Key Features

➢ Universal Meter Compatibility – Supports electricity, water, gas, and thermal meters.

➢ Frequent Data Collection – Enables high-resolution readings at short intervals.

➢ Validated Billing Data – Ensures secure, tamper-proof consumption records for

invoicing.

➢ Live Data Transmission – Sends real-time data to central systems via a stable wired

connection.

➢ Advanced Energy Monitoring – Visualizes consumption patterns for insights and

optimizations.

➢ EED-Compliant – Supports informative billing in line with the EU Energy Efficiency

Directive.

‍

Benefits

✓ Highly stable and immune to electromagnetic interference.

✓ Suitable for environments with dense infrastructure or restricted wireless access.

✓ Long cable lengths (up to 2 km) without signal repeaters.

‍

Wireless M-Bus – Secure, Flexible, and On-the-Move

‍

Overview

Wireless M-Bus (EN 13757-4) is designed for remote, low-power meter reading using wireless radio frequencies (typically 868 MHz). It enables utilities to collect meter data using walk-by, drive-by, or fixed network methods without requiring direct physical access.

‍

Key Features

➢ Mobile Data Collection – Enables reading via handhelds or mobile units.

➢ No In-Person Access Required – Perfect for hard-to-reach or secured locations.

➢ AES-128 Encrypted Communication – Ensures secure data transmission.

➢ Ideal for Water, Heating, and Cooling Meters – Especially effective for thermal

energy networks.

➢ Battery-Friendly – Designed for ultra-low energy consumption and long operational life.

‍

Benefits

✓ Reduces operational costs by eliminating the need for site visits.

✓ Quick and cost-effective deployment in both new and retrofit projects.

✓ Compatible with OMS (Open Metering System) for multi-vendor interoperability.
