Radio segment for the single-jet water meter AQUARIUS S. Usable for optimum reading with difficult access.
The IZAR RADIO SEGMENT consists of an eletronic unit, which receives and saves meter information in the form of pulses. The radio module sends the meter number, meter reading and various items of operating information every 128 sec. The data can be received by a mobile or static receiver.
Mobile: The IZAR MOBILE tablet collects the data in walk-by or walk-in mode in conjunction with the DIEHL BLUETOOTH RECEIVER. The data for the reading route is sent directly to the central PC.
Static: DIEHL RECEIVER (M-Bus, LAN, WLAN, GPRS) collects and saves the data and transfers it cyclically to a control centre (e.g. IZAR CENTER, web server).
