(2) Explanations of Parameters
1) PRIMARY_VALUE_TYPE (Relative Index 13)
Indicates the type of the measured item
represented by PRIMARY_VALUE. For the
digitalYEWFLO, the value of PRIMARY_
VALUE_TYPE is 100 and 101 as follows:
100 = Mass fl ow
101 = Volumetric fl ow
65535 = Other
Default: 101 (Volumetric fl ow)
2) PRIMARY_VALUE_FTIME (Relative Index 30)
Defi nes the damping time constant for
the fl ow rate to be input to the fl ow rate
calculation.
Setting range: 0 to 99 (seconds)
Default: 4 (seconds)
3) THERMOMETER_FUNCTION (Relative Index 48)
Determines the use of the temperature
monitoring function for a model with the MV
option.
