Alarms
As well as the regular calls to transfer data,
alarms
can be configured on the
Hydro-Logic
®
Flexi Logger 100 so that certain site conditions are detected and
trigger a data transfer to the telemetry server. Alarm information from site is then
forwarded from Timeview to individuals or groups.
Harvest software is used for configuring alarms. There is also some setup
required on Timeview.

returns to normal.
Hysteresis
This is used to prevent multiple alarms if the sensor value is near the set point.
