**) The peak flow rate is a value averaged over 2 seconds.
The recording intervals of the first data logger are programmable between 1 minute and 1440 minutes (1 day). The data loggers can be program-
med and read out via SensusRF radio.
11. Radio
11.1. General
The Cordonel is equipped with a radio interface in the license-free 433 MHz or 868 MHz band. To use the radio data, the user must have appro-
priate receivers of the same frequency, e.g. Sensus SIRT. The radio is switched off upon delivery. It can be switched on either by radio command
or automatically by watering the pipe. The radio data are secured by a 128 bit key.
11.2. SensusRF
SensusRF is a licence-free radio system with a combination of uni-directional and bi-directional radio. The meter sends a short data telegram (BUP)
every 15 seconds. After every fourth BUP, the meter listens for a short period (LAT) as to whether further information is requested. If a radio com-
mand (PAM) is received during this period, the meter sends the corresponding information (SEMI). The meter can also be configured via the PAM.

11.3. wM-Bus (OMS)
The Cordonel transmits a wM-Bus data protocol according to EN13757-4:2013.
The Cordonel supports T-mode and C-mode. Standard setting is T-mode and a transmission interval of 1 hour. The settings are changeable with
the Diavaso Config app in the range of 15 to 240 minutes.
11.4. Radio data security
The data telegrams of the Cordonel are encrypted via 128 bit. The data key is assigned to the radio address of the meter and must be stored in the
Cordonel
