Principle of operation
The IZAR RADIO COMPACT ACM consists of an electronic unit, which receives and saves meter information in the form of real data. The radio module sends the meter number, meter reading and various items of operating information in a defined sending scheme. The data can be received by a mobile or static receiver.
Mobile: The IZAR@MOBILE 2 TABLET collects the data in walk-by or drive-by mode in conjunction with the IZAR RECEIVER BT. The data for the reading route is sent directly to the central PC.
Static: An IZAR RADIO DATA CONCENTRATOR (IZAR RDC) collects and saves the data and transfers it cyclically to a control centre. -
