The Q AMR system

Data comes on demand, efficiency all by itself
Q AMR, the Automatic Meter Reading System from QUNDIS, is the leading system for radio technology on the market. All consumers normally found in households can be recorded with meter reading devices, and the values transmitted wirelessly to network nodes installed in the corresponding system. Each of these network nodes has all the consumption information - thanks to continual data exchange between the devices - which means all the data are always completely available and can be read out from any network node. This can take place via the interface at the node, by radio from a (stationary) vehicle or via a gateway by modem or IP interface from a remote location. Although the principle is highly versatile, its application is quite simple. From straightforward installation of metering devices and network nodes through to self-configuring radio technology.

How Q AMR works
The main benefit of Q AMR is that consumption readings can be taken centrally and directly from the billing office for systems of any size. Via a GSM phone network, GPRS or via computer or broadband cable networks – simple, quick and with an exceedingly high level of data security. Data collected in this way can also be used for services such as statistics for the housing industry or showing changes in consumption for tenants. Q AMR is compatible with the KNX European standard for home automation. Its standardised interfaces make it easy to connect this system to other "systems" (such as heating regulation and controlling of lights or blinds).

Network nodes and gateways
The network node is at the core of the Q AMR remote readout system, receives the consumption data from the meters and distributes them within the network. Each individual network node can provide all the values for reading out because of their ability to communicate with each other. Values are read out on-site at any network node via a cable connection or per radio from any point within the transmission radius. Gateways allow remote meter readout via various communication interfaces: GSM, GPRS or TCP/ IP.

Impulse adapters
The Q AMR networks are open for the integration of external meters with a contact output. Each impulse adapter has two independent inputs so that different meters can be connected to one impulse adapter for connection to the Q AMR remote meter reading system. For example a gas meter and an electricity meter.
