IZAR RADIO EXTERN PULSE
IZAR RE PULSE radio module is designed for remote meter reading in mobile or fixed network mode. IZAR RE PULSE can easily be connected to meters equipped with pulse emitters, open collector interfaces NPN or dry contact.
IZAR RE PULSE transmits the meter index and alarms every 8 seconds via a unidirectional radio link enabling an efficient drive-by reading at 50 km/h and an accurate fixed network.
IZAR RE PULSE offers multiple functions (historical index value, remaining battery lifetime...) and alarms (leaks detection, meter stopped, backflow...).
- Easy installation
- For all types of meters with dry contact or open collector interface
- Available in 868 MHz and 434 MHz
- IP 68
- Battery powered with a lifetime of up to 15 years
- Leak detection and transmission of alarm
Principle of operation
IZAR RE PULSE collects information coming from a pulse emitter or a meter equipped with a pulse output and transmits in real time the index and other operating information every 8 seconds in R3 mode.
Mobile reading in Walk-by / Drive-by / Passive Drive-by :
The data sent by IZAR RE PULSE is collected using either a Diehl Metering handheld computer or a tablet equipped with an IZAR RECEIVER BT for Walk-by/Drive-by or an IZAR RDC VEHICLE for passive Drive-by. Data is then transferred directly to a centralized monitoring system.
A fixed receiver IZAR RDC STANDARD/IZAR RDC BATTERY (fixed network R3) installed in buildings will collect the data and send it at predefined intervals via GPRS or LAN to a centralized server. Reading through M-Bus application with an IZAR CENTER associated to an IZAR RECEIVER M-BUS and IZAR@NET 2 software is also possible.
