[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 forB21/C40: Base Flow Unit,

“/s” is set forB22/C41: Base Time Unit,

“10” is set forB23/C42: Flow Span,

“Yes” is set forC47: User Span Select,

“dl/s” is set forC48: Flow User

Unit,

“100” is set forC49: Flow User

6. PARAMETER DESCRIPTION

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 m3

Item	Totalization display
0	12345678 m3
1	1234567.8
2	123456.78
3	12345.678
4	1234.5678
5	123.45678
6	12.345678
7	1.2345678

[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 m3/h, the second range = 100 m3/h, and the Total Low Cut = 3%, no totalization is carried out at flow rates of 0.3 m3/h or lower.
