Signal Output --> Analog Output allows you
to specify the mapping of flow rate to the
current value at the 4 to 20 mA analog
output signal. The mapping is specified by
two points on a straight line.
Signal Output --> Pulse Output allows you
to specify the mapping of flow rate to the
frequency of pulses at the digital output
signal. The mapping is specified by two
points on a straight line.
Data Logging --> Log Interval allows you to
specify a regular periodic interval in
seconds, at which flow rate and flow total
will be recorded in a log entry. The factory
default setting is 180 seconds. (see section
7.6 below for more on data logging).
Data Logging --> Log Rate Setpoint allows
you to specify upper and lower flow rates
which, when crossed, will result in log
entries being generated.
Data Logging --> Log Total Setpoint allows
you to specify five total flow values at which
log entries will be generated.
SOS Alarm --> Percent Error Window
allows you to define the percentage of fluid
sound speed change that is acceptable before
an error alarm is triggered. The default
value is 10%. See the index at the back of
this manual for fluid sound speed data.
SOS Alarm --> Error Type allows you to
define the type of error that will result when
the measured fluid sound speed has
exceeded the limit window. When Warning
is selected, the meter will log and display a
warning and flow measurement will
continue. When Fault is selected, the meter
will log and display a fault condition, flow
measurement will cease, and the meter will
enter the faulted state. See section 4.8 for
information on faults and warnings.
