The M-bus System: Instantaneous control, flexible reaction

- The most modern electronics for a proven system

The istameter® mbus is a mechanical water meter whose modular structure forms the basis for integration into the symphonic mbus system.
Both cold and warm water meters can be upgraded with a radio module at any time without great efforts. The istameter® mbus is a multi-jet impeller wheel meter with magnetic coupling and a roller-type counter. The multi-jet principle ensures an even load on the bearing.
All istameter® mbus have a sensor disk in the shape of a reflecting segment located on the calculator of the water meter. The electronic recording method of the sensor disk (optical or capacitive) ensures undelayed and exact measuring in the long run.

Performance features

The istameter® mbus is available for a nominal flow of 1.5 m3/h as warm or cold water meter. The M-bus records the following values:

• Current measuring value
• 18 end of month values
• 2 billing date values

Transmission from the meter to the M-bus module takes place electronically and reactionless together with backflow detection.

Interfaces

Programming and readout is also possible via the integrated optical interface with the M-bus module besides data transmission via M-bus.

Your benefits

• Trend-setting technology through modular structure
• Long service life ensured by an especially powerful battery
• Safe protection against dust and water jets due to high density.
• Compatible with all accessory parts listed so far
• Effortless exchange thanks to the istameter® principle
• Manipulation safety by sealing the meter and the module with a seal ring
• Manufacturer certification acc. to ISO 9001
• The CE label secures electronic compatibility
  in the domestic and the industry sector

sensonic is a heat meter tailor-made for measuring heat consumption in dwellings.The sensonic calculator can be combined with contact water meters for use with larger flow rates.  The compact device is available for flow rates of 0.6/1.5 and 2.5 m?/h

Since it is equipped with an M-Bus interface, the pulsonic II mbus permits the integration of conventional equipment with contact outputs. In addition to the possibility of combining it with M-Bus, it has a much wider range of application. 
The pulsonic II mbus is simply connected to a meter with a contact output; it stores the measured values and transfers the data to the level converter. The connection can be via an SO interface to DIN 43864. So it is also possible to integrate equipment which has already been installed in the M-Bus system. Such equipment can be conventional ista meters but also equipment of other companies, such as gas, oil and electricity meters.

The system pulses have to be converted into corresponding data so that all the devices integrated in the M-bus network can be read conveniently and clearly by a PC or laptop. This is where the level converter LC 250 comes in.

The clearly structured software M-bus VIEW is used for reading and data management of M-bus systems on a PC or laptop.
All properties and device-specific values can be managed without any problems. All consumption data can be presented on html pages suitable for the Internet. The M-bus VIEW software can be operated in various languages.

The bus switcher permits the reading of up to 2000 meters via a level converter, as well as remote meter-reading via a modem. A maximum of 250 meters can be integrated in a conventional M-Bus system.
Installation in larger properties, e.g. commercial premises, with more than 250 meters generally involves the installation of several level converters or several modems for remote meter-reading.

The connect box can be used as an alternative to the level converter LC 250 for mobile reading. The combination of an earthed socket outlet and the three-pole, in-line connect box is for supplying power and connecting a mobile level converter to the existing M-Bus network in the building. Thus the advantages of central meter-reading via M-Bus can be used without installing a level converter.
