●
Event hysteresis
If the instantaneous flow rate switch is selected as the event type, a hysteresis
(operation gap) can be set. Setting range is 0 to 10 % FS at 1% interval.
●
Event on delay
If the instantaneous flow rate switch is selected as the event type, a delay before the
event turns ON can be set. Setting range is 0 to 60 seconds at 1 second interval.
●
Event standby
If the instantaneous flow rate lower limit event is selected as the event type, the
event output can be temporarily disabled until the flow rate has exceeded the lower
limit once after the power is turned on.
■
Selection of pressure correction for pipe direction
By means of the operating pressure setting, the
MCF
can cancel the effects of pres-
sure characteristics by adjusting the output.
■
Reference temperature selection
The reference temperature can be set at 1 °C intervals between 0 to 35 °C. The fac-
tory setting is 0 °C.
■
Low flow cutoff
The low flow cut can be set at 1 % intervals from 1 to 50 % of the full-scale flow
rate. The factory setting is 1 %.
As an example of how the low flow cutoff operates, if it is set at 1 %, the display
shows “0” for flow rates from 0 to 1 % of the full-scale flow rate. This setting
affects the instantaneous flow rate, integrated flow, and analog output.
■
Self-diagnosis function
If there is an abnormal output from the sensor, or a memory error, the
MCF
’s self-
diagnosis function turns on an alarm. For details on alarms, see Alarm codes and
remedies in chapter 6, Maintenance and Troubleshooting.
