ALARMS DETAILS

Leak detection
Low battery
Meter stopped or blocked
Meter sizing :
under calibrated
Meter sizing :
over calibrated
Radio disconnected
Backflow
Alarm reset: alarms are reset automatically after a programmable period. This period must be
compatible with the frequency of reading.
Any radio module delivered already clipped on a meter has a predefined profile. Any
modification may affect the operation of the product. Diehl Metering shall not be held
liable for any malfunctioning of the product following a modification of configuration.
Alarm triggered:
- if there is a continuous consumption over a programmable period
of time, usually several days.
The alarm is set when the remaining lifetime of the battery is lower
than 1 year. The typical lifetime is up to 15 years when the
temperatures are distributed evenly within the ranges given below:
Temperature range
-15°C to +5°C
+5°C to +30°C
+30°C to +55°C
NB: an extended use at high temperatures will cause a loss of
battery autonomy. If, for example, the module is permanently at
+55 °C, the life expectancy of the radio will be reduced to 10 years.
Alarm triggered:
- if no consumption has been recorded over a programmable period
of time, usually several weeks.
Detection of undersized meter compared to the need, leading to a
meter overflow.
Alarm triggered:
- if a Q1 programmable flowrate is exceeded during a D1
programmable duration.
Detection of oversized meter compared to the need, leading to a
meter underflow.
Alarm triggered:
- if a Q2 programmable flowrate is never reached during a D2
programmable period.
Alarm triggered:
- if the radio is disconnected from its meter.
Alarm triggered :
- if a backflow is greater than a programmable value, usually a few
tens of litres.
