Status Output Function*:
Flow Switch:
In case fl ow rate decreases under the fl ow set
value,a status signal is output.
Status signal output mode can reverse (ON/
OFF).
Data Security During Power Failure:
Data (parameter, totalizer value, etc) storage
by EEPROM. No back-up battery required.
Correction:
Instrument Error Correction:
Vortex fl owmeter instrument errors can be
corrected by segment approximations.
Reynolds Number Correction:
Output error at Reynolds number 20000 or
less is corrected by using fi ve-break-point line-
segment approximation.
Gas Expansion Correction:
When measuring a compressibility gas and
steam, this expansion factor is useful to
correct the error at high velocity of fl ow (35m/s
or more).
Down-scale or Up-scale burn out.
In case a CPU or EEPROM failure occurs,
fl ow meter output the signal of Up-scale (21.6
mA or more).
Up-scale or Down-scale (3.6 mA or less) is
user-selectable through the fail mode alarm
jumper.
Indicator:
Flow rate (% or engineering units) or tem-
perature value and totalizer can be indicated
simultaneously.
Short message for self diagnostics indicated.
Local parameter setting can be operated by
key switches.
In mounting direction, the right and left 90° is
rotatable.
EMC Conformity Standards:
EN 61326-1: 2006 Class A, Table 2 (For use in
industrial locations), EN 61326-2-3: 2006
Note1: This instrument is a Class A product, and it is
designed for use in the industrial environment.
Please use this instrument in the industrial
environment only.
Note2: Use the metal conduit for the remote cable.
