Smart measurement of water and heat consumption

Smart measurement

of water and heat consumption

THIS TERM HAS RECENTLY BEEN USED VERY OFTEN, NOT ONLY IN CONNECTION WITH THE MEASUREMENT OF WATER AND HEAT. WHAT CAN WE CALL „SMART“ IN THE FIELD OF WATER AND HEAT MEASUREMENT NOWADAYS?

Probably not, because we can read the meters either visually or remotely. However, we can „smartly“ handle the read data and further process the data so that it has some meaning or benefi t and perhaps even overlap into other areas. In general, if we want to manage something, we must obtain real data for this activity correctly and on time. To this end, we have developed a comprehensive solution that ensures the timely and reliable delivery of data from meters where it is necessary to work with them.

: Gauges as basic building blocks

When measuring water and heat consumption in apartment buildings, the relevant water meters and heat meters are installed in the individual apartments. And these are the main „building blocks“ of the whole system. The sources of the measured values and their parameters and reliability directly determine whether we receive the correct data or not. In this regard, it is necessary to choose carefully and more than low cost to choose proven reliable meters. Subsequent steps implement the mere transfer of measured data for further processing.

: How the whole solution works

Central data collection from water meters and heat meters (netmetering) is realized through a fi xed network, which is installed in common areas of the building or in other suitable places. The fi xed network consists of electronic devices - so-called dataloggers and repeaters. A datalogger is basically a local computer that collects and stores data in its own memory. The installed datalogger is connected to the Internet and sends the received data to the selected FTP server. The sending takes place automatically at regular intervals. We recommend sending data once a day. Repeaters are devi-

ces that are installed between the datalogger and the read meters, they are so-called signal amplifi ers, which transmit data from the meters directly to the data logger. Repeaters and data loggers communicate with meters and with each other wirelessly. Data can be read from meters that transmit in the wireless MBus EN 13757 protocol. In terms of capacity - one datalogger can receive and store and send data from a maximum of 2,500 meters. The number of repeaters is determined by the construction and size of the building.

: How the read data is processed and displayed

To automatically process and display the readings, we have created the ACOMM application, which provides all this on a regular basis. It is a web application that allows several levels of access. Access will thus be given to both administrators, members of the Flat owners´ association Committee and end consumers. The aim of the application is to make data from individual meters available at any time of the day or night. The application shows the structure of the house with individual meters. In addition to the status of meters, there is also a history of consumption in the form of tables and graphs, year-on-year comparison of consumption, data of planned meter replacements, etc. Of course, data exports for billing and further processing. The export format is solved individually depending on the needs of a specifi c customer. The whole system is designed so that the application is installed on the server of the customer (management company), so the data always remains at the administrator.

: What gauges can be read

The whole system can read diff erent brands of meters, it is always necessary to test a specifi c brand and type of meter. We recommend Maddalena water meters and heat meters, especially based on long-term experience. It is an Italian manufacturer of water meters, whose history dates to 1919. Today, Maddalena manufactures more than 3 million water meters and heat meters per year and supplies them to 63 countries around the world. The exclusive representative for the Maddalena brand in the Czech Republic is the company Hannso s.r.o. based in Hradec Králové, which has a network of authorized partners throughout the Czech Republic.
