1) The instantaneous flow rate is the mean value of the logger period
2) The peak flow rate is the mean value over 2 seconds

14. Temperature measurement
The Cordonel measures the water temperature. The measurement is performed directly by the ultrasonic signal. The measured temperature is
shown on the display in line 2 and can be transmitted by radio via the SEMI data protocol of SensusRF.
15. Optional pulse output
The Cordonel is equipped with a slot for a pulse adapter.
If the Cordonel is delivered without a pulse module, the slot is fitted with a dummy to protect it against contamination.
The dummy must be removed before installing the pulse module. When doing so, make sure dirt does not enter the slot. If the slot is dirty, it must
be cleaned carefully by rinsing and wiping it with a soft cloth. Avoid scratching the surface.
If the pulse module has been installed, the cable must be routed directly from the Cordonel meter towards the bottom of the meter.
Never wind the cable around the head of the meter.
16. Time stamp
The Cordonel has a real time clock (RTC) from which time and calendar are derived. By default, the time is set to UTC.
Most reading systems display the meter results in local time because they take into account the offset to UTC. It is therefore generally not neces-
sary to change the time in the Cordonel.
17. Maintenance and cleaning
Under normal operating conditions, the meter is maintenance free. The meters can be cleaned however, if necessary. Do not use chemicals,
high-pressure cleaners or sharp-edged tools when cleaning (please observe section 8.2).
18. Transportation
• The meters should be transported dry, as frost-free as possible and under hygienically harmless conditions.
• If possible, the meters should always be transported in the individual packaging supplied in order to avoid damage and soiling.
• Transportation temperature:
Standard conditions: -10 °C ... 40 °C
for one week: -40 °C ... 60 °C
19. Storage
• The meters should be stored in a dry, dust-free place and under hygienically harmless conditions.
• If possible, the meters should always be stored in the individual packaging supplied in order to avoid damage and contamination.
• Storage temperature:
Standard conditions: -10 °C ... 40 °C
For one week: -40 °C ... 60 °C
20. Disposal
The Cordonel meter contains lithium batteries and must therefore not be disposed of with household waste.
