6. PARAMETER DESCRIPTION
[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 Density.
[C46: Mass 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.
[C47: 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 C48: Flow User Unit and
C49: Flow User Span.
[C48: Flow User Unit] Setting of the special flow
rate units
This parameter is used to select the special units (up to
maximum of 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.
[C49: Flow User Span] Setting of the special flow
rate span
This parameter sets the special flow rate 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 C47: User Span
Select,
“dl/s” is set for C48: Flow User
Unit,
“100” is set for C49: Flow User
Span.
“100 dl/s” is indicated for 100%
output in the Display Mode.
(3) Menu D: Total Setting items
Menu D contains parameters that are relevant to
totalization function settings.
[D10: Total Unit] Setting of units for totalization
scale
→ Refer to the description of parameter B30.
[D11: Total Scale] Setting of the totalization scale
→ Refer to the description of parameter B31.
[D12: Total Decimal Pnt] Setting of the decimal
point position for the totalization display
This parameter sets the position of the decimal point
for totalization display in terms of the number of digits.
Except in cases where 0 is selected, the totalized units
are not displayed.
Example: When totalized value is 12345678 m

[D13: Total Low Cut] Setting of the totalization stop
range
This parameter allows the settings to be made that
prevent totalization when the flow rate is at or below
the low-cut setting value. In cases where there are
multiple ranges or forward/reverse ranges, low cut is
carried out at the setting value for the smallest span
(i.e., an integer between 0 and 10%).
Example: When the first range = 10 m
3
/h, the second
range = 100 m
3
/h, and the Total Low Cut =
3%, no totalization is carried out at flow
rates of 0.3 m
