Radio-system RFis an advanced Walk-by/Drive-by or a fixed wireless radio system for wireless remote reading via license-free radio frequency 868 MHz. With radio system RF, measured values can be read from meters with radio system RF or wM bus. With this radio communication system there is the possibility of measurement management for further process and analysis as well as the ability to create data that is transferred to the billing-system.
Suitable applications are for reading limited-access gauges, for example, in a water-filled well. Can also be used for individual measurement in terraced areas or areas with large geographical spread.
The system is flexible and can easily be expanded and supplemented with more transmitters/gauges.
Using Android based mobile application DIAVAZO, route planning, addressing of gauges, transfers to existing billing system, etc. are performed.
The advantages of radio-based remote reading:
Improves the readout/reading:
- Unbroken data chain from meter to debit system
- Reduces the risk of error debts
- Easier to read more often which increases consumption / leakage
- With wireless reading, limited access meters can be read easily and easily (eg well meters) - do not need to drain the meter well and do not climb it to read the meter.
- Wireless reading meter where only authorized personnel have access, pharmaceutical companies etc. - Saves portkeepers, codes, courses etc.
- Sit in the car and read
- Read multiple meters from a reading point
- Transfer and configure measurement values digitally via the software to the debit system, which provides increased data security
- Complete easily with more meters or transmitters - no wiring or conjugation changes.
Improves the working environment:
- Avoid workplace accidents
- Release climbing into the well
The system consists of the following components:
Meter's that are used in the RF radio system shall be equipped with an integrated electronic register or alternatively equipped with an HRI-trick or open-collector pulse output or radio-transmitter reed.
Examples of meters with integrated electronic register are AT 7450, AT 7440.
AT 7275RF, AT 7275HRI-RF and 7275MEI-RF are transmitters that enable HRI-triggers or alternate open-collector or reed pulse outputs to be integrated and communicated with RF radio system. These can be used in both mobile and fixed radio networks.
The transmitters can be configured with the radio modem AT 7087SIRT together with DIAVASO (mobile application).
Radio-system RFoffers two communication routes, single and bi-directional communication. The one-way communication is called BUP (Bubble UP meter Reading Packet Format).

DIAVASO is a mobile application with several underlying applications for remote reading of metrics via Android-based mobile or tablet. The DIAVASO application consists of various individual applications, RF Finder, Collection Station, Collection Mobile Configuration & Service and Data Logger. These can be used individually or in combination, depending on your system requirements for remote reading (AMR) or for small scale fixed networks (AMI).
Mobile applications are compatible with most Android-based smartphones and tablet and communicate with the SIRT radio modem. DIAVASO is compatible with all meter and repaters communicating via RF radio system.
The applications are designed to be used for installation of measurement points, remote reading, maintenance and configuration of gauge and repeaters, and handling of reading routes. The Collection Mobile application can also communicate with web server to handle workflow for metering, reporting and data exchange with billing systems.

In a system consisting of many meter where all or part of the them are geographically collected. Meters are read with integrated electronic register or transmitted with RF radio communication to the SIRT radio modem. The software defines which meters are included in each reading point. You can build the system in any way.
- Radio modem that can easily be mounted in the car holder. With the help of an external roof rack, the range increases and the meter can be read from a long distance and can be left in the car while reading.
- The radio modem is connected to an existing laptop that is included in the car or via bluetooth connectivity to Android based mobile application.
In a system consisting of a maximum of 1000 meters, all meters are automatically read to a collection device, a so-called gateway. The gateway then sends the signal via the GPRS network and an existing FTP server to your network server. The system is built with radio repeaters AT 7087REP-RF, which receives the measurement values from the meters and relayes to the AT 7087GW-RF collection unit or another radio amplifier. Using an Excel-based program, the measured values are automatically recorded with a preset time interval. The server is automatically notified when alarms, such as cable breaks and low battery levels.
