Explanation
79 2079 REFEREnCE_DEnSItY 1.0 kg/l o/S this parameter indicates a reference density
value.
When the value of DEnSItY_FIX_VaL is
“Inhibit” users can not change this value and
this function does not perform. When the
value is “Enabled” users can change this
value and this parameter is used as reference
density for calculation of volume flow.
80 2080 DEnSItY_oFFSEt 0 g/l o/S this parameter indicates a density offset
value.
81 2081 tEMP_FIX_VaL_SELECt Inhibit o/S this parameter enables the function of
tEMP_FIXED_VaLuE.
When the value is “Inhibit”, the function of
tEMP_FIXED_VaLuE does not perform.
When the value is “Enable”, the function of
tEMP_FIXED_VaLuE performs.
82 2082 tEMP_FIXED_VaLuE 30°C o/S this parameter indicates a fix temperature
value.
When the value of tEMP_FIX_VaL is
“Inhibit” users can not change this value and
this function does not perform. When the
value of tEMP_FIX_VaL is “Enable” users
can change this value and this parameter is
set to the temperature value.
83 2083 tEMP_GaIn 1.00 o/S this parameter defines the value of tem-
perature gain. the function allows correction
of the temperature measurement for better
accuracy in mass flow and density for very
high and low temperatures.
84 2084 SEnSoR_MoDEL *) this parameter defines the sensor model.
When a user changes the value the follow-
ing parameters return to default automati-
cally:
SEnSoR_RanGE,
MaSS_FLoW_VaLuE_RanGE,
VoLuME_FLoW_VaLuE_RanGE,
nEt_FLoW_VaLuE_RanGE,
SK20, SKt, RV, QnoM,
KD, FL20, FtC1, FtCK,
SKP, FPC, SKtK, SKPt,
FPtC, FQC1, FQC2,
autoZERo_RanGE,
FLuCtuatIon_RanGE
85 2085 SK20 *) o/S Defines the sensor constant at 20°C.
the valid range and the default value de-
pend on the selected sensor model.
86 2086 SKt *) o/S Defines a linear temperature coefficient of
the sensor constant SK20.
the valid range and the default value de-
pend on the selected sensor model.
87 2087 RV *) o/S Defines a density correction factor.
the valid range and the default value de-
pend on the selected sensor model.
88 2088 QnoM *) o/S Defines the water flow rate of about
1 bar pressure drop.
the valid range and the default value de-
pend on the selected sensor model.
89 2089 KD *) o/S Defines a density calibration constant.
the valid range and the default value de-
pend on the selected sensor model.
90 2090 FL20 *) o/S Defines a response frequency of the tubes
filled with air at 20°C.
the valid range and the default value de-
pend on the selected sensor model.
*) Depends on detector size. For RCCF31 not combined with detector, data for RCCS36 are stored.
