11) BI_dIrECTION

(relative Index 68)
Enables the RotaMaSS to measure the
flow in bi- or uni-direction mode. the sign
of the calculated flow rate values depends
on the flow direction.

Setting range: Bi-Direction; uni-Direction

Default: Bi-Direction

Parameters for local display

12) dISP_SELECT_1

(relative Index 50)
Selects the data to be displayed on the
first line of the LCD indicator, as follows
(Default : Massflow) :

1 = aI1 out = Massflow:

actual mass flow rate

2 = aI2 out = Volumeflow:

actual volume flow rate

3 = aI3 out = Density:

actual density value

4 = aI4 out = temperature:
actual temperature value

5 = aI5 out = Conc Meas:

actual calculated concentration value

6 = aI6 out = netflow:

actual net flow rate

7 = It1 out = It1: Integrator 1 totalized
value

8 = It2 out = It2: Integrator 2 totalized
value

9 = VELoCItY: actual medium´s velocity

6) VOLUME_FLOW_LOWCUT

(relative Index 32)
Sets the low cutoff volume flow rate level.

Setting range: Minimum flow rate 0 to 10%
of VoLuME_FLoW_VaLuE_RanGE.
Eu_100. the default value is 0 %.

unit: as selected in aI2.XD_SCaLE.
unItS_InDEX

Parameters for Tertiary Variable

7) dENSITy_VALUE_FTIME

(relative Index 35)
Defines the damping time constant for the
density to be input to the density calculation.

Setting range: 0.1 to 200 (seconds)

Default: 3 (seconds)

8) dENSITy_LOWCUT

(relative Index 36)
Sets the low cutoff density level.

Setting range: Minimum value 0 to 10%
of DEnSItY_VaLuE_RanGE.Eu_100.
the default value is 0 %.

unit: as selected in aI3.XD_SCaLE.
unItS_InDEX

Parameters for Quaternary Variable

9) TEMPErATUr_VALUE_FTIME

(relative Index 39)
Defines the damping time constant for the
temperature to be input to the temperature
calculation.

4) MASS_FLOW_LOWCUT

(relative Index 28)
Sets the low cutoff mass flow rate level.

Setting range: Minimum flow rate 0 to
10% of MaSS_FLoW_VaLuE_RanGE.
Eu_100. the default value is 0 %.

unit: as selected in aI1.XD_SCaLE.
unItS_InDEX

Parameters for Secondary Variable

5) VOLUME_FLOW_VALUE_FTIME

(relative Index 31)
Defines the damping time constant for the
volume flow rate to be input to the flow
rate calculation.

Setting range: 0.1 to 200 (seconds)

Default: 3 (seconds)

Setting range: 0.1 to 200 (seconds)

Default: 3 (seconds)

Parameters for flow direction

10) FLOW_dIrECTION

(relative Index 67)
Defines the direction of the flow and deter-
mines the sign of the calculated flow rate
values.

Setting range: Forward; Reverse

Default: Forward
