Monitoring Functions
Discharge:
System Stable permits continuous discharge of a preset (adjustable) amount of water.
If this amount is used in a single discharge, an alarm is issued and
the water supply is cut off.
The monitor employs two sets of limiting values for High and Low
consumption periods respectively.
Peak Flow:
System Stable permits peak flow up to a preset (adjustable) value.
If this value is exceeded for some (adjustable) time, an alarm
is issued and the water supply is cut off.
The monitor employs two sets of limiting values for High and Low
consumption periods respectively.
Mean Flow:
System Stable permits mean flow up to a preset (adjustable) value.
If this value is exceeded, an alarm is issued and the water supply is cut off.
The monitor employs two sets of limiting values for High and Low
consumption periods respectively.
Daily Consumption:
System Stable permits daily consumption of a preset amount of water. If consumption
exceeds this amount, an alarm is issued; if desired the water supply will be cut off.
Seepage:
System Stable checks that the water flow can drop below a preset (adjustable) value for a
preset (adjustable) amount of time, and issues a seepage alarm if this fails to occur
daily; if desired the water supply will be cut off.
Valve Test:
System Stable exercises the cut-off valve daily, at the same time checking tightness of the
closed valve. If this is insufficient, an alarm is issued; water supply is not cut off.

Water Supply Error:
System Stable accepts the flow meter standing still up to a preset (adjustable) amount of
time. If this is exceeded, an alarm is issued; water supply is not cut off.
Power Supply Error:
System Stable continuously monitors mains and all internal power supplies.
If any of these fails, an alarm is issued; water supply is not cut off.
Controls and Indicators:
Indicators for water consumption, valve status, alarm, warning and protection status;
2x20 LCD display for readout; buttons for manual valve control, alarm acknowledge, protection on/off;
menu-, navigation- and parameter setting keys; buzzer.
Inputs:
Digital input for switching protection on/off.
Outputs:
Alarm relay with selectable response for certain alarm types.
Signal relay for remote reading or external indication of Protection Status.
Valve relay for cut-off valve.
Digital optoisolated output for repetition of (direct or scaled) meter impulses to
other monitoring systems (e.g. FarmWatch).
Text Message Alarm:
By attachment to AERS, system Stable may
send text messages to one or more mobile phones on alarm.
