[C41: Base Time Unit] Selection of time units for
theowratespan
→ Read the description of parameter B22.
[C42: Flow Span]Settingoftheowratespan
→ Read the description of parameter B23.
[C43: Flow Decimal Pnt] Setting of the decimal
pointpositionfortheinstantaneousowrate
→ Read the description of parameter B24.
[C44: Velocity Check] Displayoftheowratespan

maximum range in m/s units.
[C45: Density Unit] Setting of the density units for
massowrate
This parameter selects the units for density as
required when making settings using C46: Mass
Flow Density.
[C46: Mass Flow Density] Setting of the density
formassowrate
This parameter is necessary in situations where
t, kg, g, klb or lb has been selected as the mass
unit in B21/C40:BaseFlowUnit. If a mass unit is
selected in B21/C40:BaseFlowUnitand a value
of 0 is set for this parameter, the setting alarm “57:
Dens Set Err” will be displayed. In such a case,
ensure that the density is set correctly.
NOTE
Example : Since the water density is about
1000kg/m
3
, set the parameter below.
“kg/m
3
” is set for C45: Density Unit,
“1000” is set for C46: Mass Flow
Density.
Set the suitable value under the actual
use because the density changes by
temperature.
[C50: User Span Select] Selection of the use of
specialowrateunits
This parameter selects whether or not special units
areusedforinstantaneousowrate.Actualsetting
of these units is carried out using C51: Flow User
Unit and C52: Flow User Span.
[C51: Flow User Unit]Settingofthespecialow
rate units
This parameter is used to select the special units
(up to maximum 8 characters in length). These
unitsaredisplayedwheninstantaneousowrate
is selected in the Display Mode, and they are
displayed for A20: FLOW RATE when BRAIN
communication is being carried out.
[C52: Flow User Span]Settingofthespecialow
rate span
This parameter sets the special span to be
displayed for 100% output in the maximum range.
NOTE
Example:Tosetthespecialowratespanto
100 dl/s
Since100dl(deci-liter)=10l(liter),
“l (Liter)” is set for
B21/C40:Base
Flow Unit,
“/s” is set for
B22/C41:BaseTimeUnit,
“10” is set for B23/C42:FlowSpan,
“Yes” is set for
C50: User Span Select,
“dl/s” is set for
C51: Flow User Unit,
“100” is set for
C52: Flow User Span.
“100 dl/s” is indicated for 100% output
in the Display Mode.
