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.
