readout device. The user receives the radio key by downloading it from a secure platform. The link to the platform will be sent to the authorised
user by email.
Caution!
The radio key must be assigned to the radio address of the meter and stored in a secure place. The loss of the radio key or incorrect
assignment leads to the loss of readability.
12. Last meter reading
Cordonel is equipped with an NFC interface, which stores and can transmit the last meter reading before failure in the case of a meter without
display and radio communication.
NFC means Near Field Communication and is a function integrated in modern mobile phones and supported by Android operating systems.
The NFC aerial of the Cordonel is arranged in a loop around the display.
For correct readout, the readout device with the NFC sensor (usually on the back of mobile phones) must be placed on the display of the Cordonel
and the app started. Sensus recommends the app NFC ST 25.
Readable values are:
• Meter number
• Last saved meter reading
• Volume unit
• Time that data was last saved
