M Bus module for remote water meter reading
The Apator Powogaz AT-MBUS-NA-2 M-Bus module connects compatible JS and JS130 Master+ and Master C+ water meters to a wired reading system. The add-on module reads the meter optically, detects flow direction and provides readings over M-Bus. It fits the corresponding cold and hot water meter versions. Manufacturer model: AT-MBUS-NA-2. Store SKU for this product listing: AT-MBUS-NA-02.
Benefits of installing the module
• M-Bus communication. Readings are available to compatible collection equipment using the PN-EN 13757-3 standard.
• Optical reading with flow direction detection. The module tracks the meter indicator and accounts for water moving in the reverse direction.
• Installation on an existing compatible meter. The module attaches to the register without altering the meter construction or verification seals.
• Event monitoring. The module records reverse flow, magnetic field exposure, removal, leakage, no flow and low battery voltage.
• Backup power. A lithium battery maintains internal counting when power from the M-Bus line is unavailable.
Water meter compatibility
Designed for Apator Powogaz JS and JS130 6.3 / 10 / 16 Master+ and Master C+ water meters in versions prepared for this optical add-on module. This covers the corresponding DN25–40 cold and hot water meter versions. Diameter or series name alone is not enough to establish compatibility: check the complete meter designation and register design before ordering.
System requirements
A wired M-Bus line, a compatible M-Bus master or concentrator, and collection software are required. After installation, a qualified specialist sets the meter type, initial reading, address and communication parameters.
Frequently asked questions
Is this a wired or wireless module? The AT-MBUS-NA-2 uses wired M-Bus. A cable connection to suitable collection equipment is required.
Does it send readings directly over the internet? An M-Bus master or concentrator reads the module. Suitable system equipment handles any onward connection to a server.
Are a water meter and concentrator included? This listing covers the communication add-on module with cable. The water meter and data collection equipment are selected separately.
