IM 01E30D01-01EN
[C41: Base Time Unit] Selection of time units for
the flow rate span
→ Refer to the description of parameter B22.
[C42: Flow Span] Setting of the flow rate span
→ Refer to the description of parameter B23.
[C43: Flow Decimal Pnt] Setting of the decimal
point position for the instantaneous flow rate
→ Refer to the description of parameter B24.
[C44: Velocity Check] Display of the flow rate span
velocity
This parameter displays the flow rate span for the
maximum range in m/s units.
[C45: Density Unit] Setting of the density units for
mass flow rate
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
for mass flow rate
This parameter is necessary in situations where
t, kg, g, klb or lb has been selected as the mass
unit in B21/C40: Base Flow Unit. If a mass unit is
selected in B21/C40: Base Flow Unit and 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
special flow rate units
This parameter selects whether or not special units
are used for instantaneous flow rate. Actual setting
of these units is carried out using C51: Flow User
Unit and C52: Flow User Span.
[C51: Flow User Unit] Setting of the special flow
rate units
This parameter is used to select the special units
(up to maximum 8 characters in length). These
units are displayed when instantaneous flow rate
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] Setting of the special flow
rate span
This parameter sets the special span to be
displayed for 100% output in the maximum range.
NOTE
Example : To set the special flow rate span to
100 dl/s
Since 100 dl (deci-liter)=10 l (liter),
“l (Liter)” is set for B21/C40: Base
Flow Unit,
“/s” is set for B22/C41: Base Time Unit,
“10” is set for B23/C42: Flow Span,
“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.
