FH8400 inputs-outputs
As an option, 2x4-20mA analogue inputs are available for pressure
and temperature display.
1 or 2 selectable 4-20mA analogue outputs are available for either
flowrate, VOS, VOF or volume reading.
Data logger and Event logger
The FH8400 includes two loggers: Data and Event logger.
The Data logger records values in a non-volatile memory (756
available records), with a storage period which can be chosen
from 1 s to 24 h, such as the counting mode, the flow-rate value,
and the flow velocity (see the complete list of stored data).
Remark : The total recording duration depends on the selected period. The
table below gives the recording duration for several period values.
The event logger records in a non volatile memory (756 available
records) some events such as the FH8400 power on or off, the
change of state of the alarms, the changeover from a counting
mode to another (see page 88 for the complete list of recorded
events).
