Explanation
82 2082 NOISE_RATIO — — Indicates the noise balance ratio. When the value of
NOISE_BALANCE_MODE is 1 (Auto), this value cannot
be modifi ed. When it is 2 (Manual), the desired value can
be set as a fi xed ratio.
83 2083 SIGNAL_LEVEL 1 O/S Sets the signal level. Setting range: 0.1 to 20.0
84 2084 FLOW_VELOCITY — — Indicates the current fl ow velocity in m/s (1061); updated
periodically.
85 2085 SPAN_VELOCITY — — Indicates the span fl ow velocity in m/s (1061); updated
periodically. (This parameter is set to the value calculated
based on the density under the normal operating
conditions and normal operating temperature specifi ed by
the customer.)
86 2086 VORTEX _
FREQUENCY
— — Indicates the current vortex generation frequency in Hz
(1077); updated periodically.
87 2087 SPAN_FREQ — — Indicates the vortex generation frequency at the span
fl ow in Hz (1077); updated periodically. (This parameter
is set to the value calculated based on the density under
the normal operating conditions and normal operating
temperature specifi ed by the customer.)
88 2088 FLUID_DENSITY — — Indicates the fl uid density calculated based on the
temperature data, in the unit determined by DENSITY_
UNIT; updated periodically.
89 2089 SENSOR _ERROR
_RECORD
0 O/S,
AUTO
Record of the following errors regarding the sensor. This
record will be automatically cleared when no error has
occurred for a month.
Recorded errors: Flow over output, Span set error, Pre-
amp fault, EEPROM fault, Sensor fault, Transient noise,
High vibration, Clogging, Fluctuating, Temp over output,
Over temp, Temp sensor fault, Temp convert fault.
Setting range: 0 only. Setting 0 clears the record.
90 2090 MODEL digitalYEWFLO O/S,
AUTO
Model of the fl owmeter converter
91 2091 ALARM_SUM 0 O/S,
AUTO Indicates the entire block’s alarm statuses; Disable can
only be set.
153 2153 VOLUME_FLOW — — Indicates the volumetric fl ow rate.
154 2154 VOLUME _FLOW_
UNIT
— — Indicates the unit of VOLUME_FLOW. It links the unit of
XD_SCALE of AI3.
Note 1: The value changes in line with a change to the SIZE_SELECT value or to the unit setting in XD_SCALE of the corresponding AI
block.
Note 2: An intended value which meets both of the following conditions can only be written: CAL_POINT_LO < the intended value, and
SENSOR_RANGE.EU100 > intended value.
Note 3: An intended value which meets both of the following conditions can only be written: CAL_POINT_HI < the intended value, and
SENSOR_RANGE.EU100 > intended value.
Note 4: The fl ow rate unit can only be written.
Note 5: These parameters are set in accordance with the specifi cations written in the registered sizing data if it is supplied.
In case of UNCALIBRATION order, they are set to the defaults when shipped.
