Flow Lo; Log I; Log T; Thresh - Universal Flow Monitors FlowStream FD Series User Manual

FLOW LO: Low set point for flow alarm.
LOG I: Time interval between data samples logged to USB memory stick.
LOG T: Total datalogging time in minutes.
THRESH: Threshold percentage for filtering noisy flow readings.
value (in percent) determines which samples will be left out. Percentage is with respect
to the internal moving average. Range is 3-50%. For example, when Threshold is set to
20%, if the moving average is 100 SCFH and a single flow sample is either above 120
SCFH or below 80 SCFH (i.e. 20% of the average), it will be ignored and not added to
the moving average
then they will be counted in and the moving average is updated with the new values
(more than one sample signifies a real change in flow, not noise).

Range is 0 to FLOW HI – 2% FS. If set to 0, alarm is
disabled. Alarm hysteresis is 1% FS.
Use SET, UP, DOWN buttons as explained above to
change the set point.
Range is 0.1 to 999.9 seconds.
Use SET, UP, DOWN buttons as explained above to

Range is 1 to 9999 minutes. If set to 0, it records
data without any time limits (until memory is full).
