Imagine a building where several hundred meters of all kinds – water meters, heat meters, cooling meters, gas and electricity meters – have been installed. Now imagine that all of these meters could be selected from a central computer within minutes.
In practice, such situations use cable bus systems. M-bus (meter-bus) and our specially developed ZR-bus (ZENNER-bus) are intelligent system solutions for smart remote reading of water, energy, electricity and gas meters.
Bus systems are used in properties where structural or infrastructure conditions mean that it is not possible or economical to use a radio system. These include larger commercial properties, industrial facilities, hospitals and airports.
ZENNER offers such properties a comprehensive product range containing all the components needed to connect meters to a smart, cable remote readout system using transfers in accordance with the M-bus standard (DIN EN 1434). In addition to meters with an integrated bus interface, you can also integrate meters with pulse output into the bus system via pulse counters.
The main components of our bus systems are electronic communication interfaces in the energy calculators of our heat meters and pulse counters. We use bus converters (level converters) to supply power to the bus segments and as interfaces to the PC or transmission equipment (e.g. CommunicationMaster with Ethernet or GSM interface).
For the remote reading and transmission of data in energy monitoring or energy management systems, we offer our customers modular software packages perfectly adapted to all of their individual needs.
