Explanation
63 2063 SECOND_TEMP
_COEF
0 O/S Sets the second temperature coefcient for the density
compensation of a liquid.
Setting range: –32000 to 32000
Unit: 1/TEMP_UNIT^2
64 2064 SIZE_SELECT 25 mm (2) (Note 5) O/S Selects the owmeter size: 1 = 15 mm (1/2 in.); 2 = 25 mm
(1 in.); 3 = 40 mm (1.5 in.); 4 = 50 mm (2 in.); 5 = 80 mm
(3 in.); 6 = 100 mm (4 in.); 7 = 150 mm (6 in.); 8 = 200 mm
(8 in.); 9 = 250 mm (10 in.); 10 = 300 mm (12 in.); 11 =
400 mm (16 in.)
65 2065 BODY_TYPE Standard (1) O/S Selects the owmeter body type: 1 = Standard; 2 = High
Pressure; 3 = Low Flow Unit (1); 4 = Low Flow Unit (2)
66 206 VORTEX _
SENSOR_TYPE
Standard (1) O/S Selects the vortex sensor type: 1 = Standard; 2 = High
Temperature; 3: Low temperature.
67 2067 K_FACTOR_UNIT p/L (1) O/S Selects the unit of the K factor.
68 2068 K_FACTOR 68.6 O/S Sets the K factor of the combined detector at 15°C.
Setting range: 0.00001 to 32000
69 2069 LOW_CUT_FLOW 0.46687 (minimum
gas ow rate for the
size of 25 mm [1 in.])
O/S Sets the low cutoff ow rate level. Setting range: Minimum
ow rate x 0.5 to XD_SCALE.EU_100. The unit selected in
PRIMARY_VALUE_RANGE.Units Index applies.
70 2070 UPPER_DISPLAY
_MODE
1 AUTO Selects the data to be displayed on the upper row of the
LCD indicator:
1 = Flow Rate (%): Instantaneous ow rate as a
percentage
2 = Flow Rate: Instantaneous ow rate in the specied
unit
3 = Temperature (%): Temperature as a percentage (can
only be selected for a mode with the MV option)
4 = Arithmetic Out
71 2071 LOWER_DISPLAY
_MODE
1 AUTO Selects the data to be displayed on the upper row of the
LCD indicator, as follows:
1 = Blank
2 = Total: Totalized ow rate
3 = Temperature: Temperature (can only be selected for
a mode with the MV option)
4 = Integrator Out
72 2072 DISPLAY_CYCLE 1 (500 ms) O/S,
AUTO
Sets the display refresh cycle of the LCD indicator, as a
multiple of 500 milliseconds. Setting range: 1 to 10 (= 0.5
to 5 seconds)
73 2073 USER_ADJUST 1 O/S User-set adjustment factor. The measured ow rate
multiplied by this factor is output. Setting range: 0.00001
to 32000
74 2074 REYNOLDS
_ADJUST
1 (Not Active) O/S Selects whether to activate Reynolds number correction: 1
= Not Active; 2 = Active
75 2075 VISCOSITY _VALUE 1 (Note 5) O/S Sets the viscosity coefcient of the process uid. When
REYNOLDS_ADJUST is set to Active, this parameter
needs to be set since it is used in the Reynolds number
calculation. Setting range: 0.00001 to 32000 [mPa•Pas]
76 2076 GAS_EXPANSION
_FACT
1 (Not Active) O/S Selects whether to activate expansion correction for a
compressible uid: 1 = Not Active; 2 = Active
77 2077 FLOW_ADJUST 1 (Not Active) O/S Selects whether to activate instrument error correction for
a compressible uid: 1 = Not Active; 2 = Active
78 2078 FLOW_ADJ _FREQ 0 O/S Sets the rst to fth breakpoint frequencies for the
instrument error correction in an array format. Setting
range: 0.0 to 32000 (unit is Hz [1077])
79 2079 FLOW_ADJ_DATA 0 O/S Sets the correcting values corresponding to the rst to fth
breakpoint frequencies for the instrument error correction
in an array format. Setting range: –50.00 to 50.00 (unit is
% [1342])
80 2080 TRIGGER_LEVEL 1 O/S Sets the trigger level. Setting range: 0.1 to 20.0
81 2081 NOISE_BALANCE
_MODE
1 (Auto) O/S Indicates the mode of noise balance ratio tuning and
allows tuning to be activated:
1 = Auto: Automatic noise balance mode
2 = Manual: Manual noise balance mode
3 = Tuning at Zero: Setting this value causes noise
balance ratio to be tuned given that the current ow
rate is zero; then after completion of the tuning, the
parameter value reverts to 2 (Manual).
