Example 1: Calculating the Span
Assume that the flowmeter generates 20mA at a flowrate of 2,481.3
Liters/minute, the selected unit is "Liters" and time unit "minute". The span
is 2481.3
Enter for SETUP 24: "248130" and for SETUP 25 - decimals span "2".
Example 2: Calculating the Span
Assume that the flowmeter generates 20mA at a rate of 652.31 USGAL
per hour, the selected unit is USG and the time unit is minute. The span is
652.31 / 60 minutes is 10.87183 (GPM).
Enter for SETUP 24: "108718" and for SETUP 25 "4".
DECS SPAN
25
This setting is used to set the amount of digits behind the decimal point for the
span.

EXPLANATION OF SETUP MENU 3 - ALARM
These settings determine how the flow rate is monitored and how the F113-A will process the alarm
conditions. For the setup of the configurable outputs, refer to setup menu: Relays.
FLOWZERO
31
When the flow rate is zero, then it is possible to ignore or disable the flow
rate monitoring. The following settings can be selected:
DEFAULT: in case of a low-flow rate alarm and zero flow, it will switch
the alarm output and indicate the alarm on the display.
NO RELAY: in case of a low-flow rate alarm and zero flow, it won't switch
the alarm output but will indicate the alarm on the display
only.
IGNORE: in case of a low-flow rate alarm and zero flow, it won't switch
the alarm output and nothing will be indicated on the display.
ALARM LL
32
This setting is used to activate the related alarm condition and to set the
threshold value for a this flow alarm. The setting 0.0 disables this alarm.
ALARM LO
33
This submenu is used to activate the related alarm condition and to set
the threshold value for a this flow alarm. The setting 0.0 disables this
alarm.
ALARM HI
34
This setting is used to activate the related alarm condition and to set the
threshold value for a this flow alarm. The setting 0.0 disables this alarm.
ALARM HH
35
This setting is used to activate the related alarm condition and to set the
threshold value for a this flow alarm. The setting 0.0 disables this alarm.
DELAY LL
36
This setting is used to set a delay time for the related alarm. When the
alarm condition is still valid after the delay time, an alarm is given.
DELAY LO
37
This setting is used to set a delay time for the related alarm. When the
alarm condition is still valid after the delay time, an alarm is given.
DELAY HI
38
This setting is used to set a delay time for the related alarm. When the
alarm condition is still valid after the delay time, an alarm is given.
DELAY HH
39
This setting is used to set a delay time for the related alarm. When the
alarm condition is still valid after the delay time, an alarm is given.
3.1.5.
EXPLANATION OF SETUP MENU 4 - DISPLAY
FUNCTION
41
This setting can be set to display total or rate.
•
When 'total' is selected, simultaneously, total is shown with the large
digits and flow rate with the smaller digits. When SELECT is pressed,
the accumulated total is shown temporarily.
•
When 'rate' is selected, only flow rate will be shown with the large
digits together with its measuring unit. When SELECT is pressed, the
total and the accumulated total are shown temporarily.
ALARM SET
42
This setting is used to determine in which menu you can change the
alarm settings. When programmed for setup menu only, the alarm
settings in the operator menu are read-only.
LIGHT
43
The backlight brightness can be adjusted from 0% (off) to 100% (full
brightness) in steps of 20%.
When the F113-A is only loop powered, the backlight is disabled. An
external power supply is required to supply the backlight.
BL ALARM
44
This setting is used to set the behavior of the backlight (bl) during an alarm
condition.
