Functions:
Damping Time Constant:
0 to 99 Sec (63% response time)
Note: Delay time is 0.5 Sec.
Analog output circuit time constant is 0.3 Sec.
Pulse Output Function*:
Pulse output is selected from scaled pulse,
unscaled pulse, frequency (number of pulses
output per second at 100% of output).
Pulse frequency: Max 10 kHz
Duty cycles: Approx.50% (1:2 to 2:1)
Self-diagnostics and Alarm Output *:
In case alarm (over range output signal, EEPROM
error, vibration noise, abnormal ow such as
clogging, bubble) occurs, an alarm signal is output
and indicated.
The alarm signal output goes from close(ON) to
open(OFF) during alarming.
Analog Output Function:
Analog output is selected from owrate and
temperature value when option code /MV is
selected.
Status Output Function*:
Flow Switch:
In case ow rate decreases under the ow set
value,a status signal is output.
Status signal output mode can reverse (ON/ OFF).
Data (parameter, totalizer value, etc) storage by
EEPROM. No back-up battery required.
Correction:
Instrument Error Correction:
Vortex owmeter instrument errors can be
corrected by segment approximations.
Reynolds Number Correction:
Output error at Reynolds number 20000 or less is
corrected by using 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 ow (35m/s or more).
Down-scale or Up-scale burn out.
In case a CPU or EEPROM failure occurs, ow
meter output the signal of Up-scale (21.6 mA or
more).
Up-scale or Down-scale (3.6 mA or less) is userselectable through the fail mode alarm jumper.
Indicator:
Flow rate (% or engineering units) or
temperature 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.

The upstream straight pipe length dependent on the element
located on the upstream such as reducer/expander, bent and etc.,
refer to description as above. Keep 5D or more for downstream

In case the valve has to be installed on the upstream of the

Refer to each element above for
straight pipe run.
For a gas line which uses a position-type or roots-type blower
compressor or a high-pressure liquid line (about 1MPa or more)
which uses piston-type or plunger-type pump, fluid vibrations may
be produced.
In these case, install valve on the upstream side of digitalYEWFLO.
For inevitable fluid vibration, put a vibration damping device such
as throttling plate or expansion section in the upstream side of
digitalYEWFLO.
Piston-type or plunger pump:
Install the accumulator on the upstream side of digitalYEWFLO to
reduce uid vibrations.
Valve positon (T-type piping exist):
When pulsation causes by a T-type piping exist, install the valve on
the upstream of the owmeter.
Example: As shown in the figure, when the valve V1 is turned off,
the fluid flow throught B as to meter A the flow is zero. But due to
the pulsating pressure is detected, the meter is zero point become
uctuating. To avoid this, change the valve V1 location to V1'.
Note: In case of the Reduced Bore Type, moisture may be
remained upstream of the owmeter. Drain it appropriately.

Pressure and Temperature Taps:
Pressure tap outlet: install this tap between 2D and 7D on the
downstream side of a owmeter.
Temperature tap outlet: install this on the downstream side 1D to
2D away from a pressure tap.
Mounting Gasket:
Avoid mounting gaskets which protrude into the pipe line. This may
cause inaccurate readings.
Use the gaskets with bolt holes, even if digitalYEWFLO is the wafer
type.
When using a spiral gasket (without bolt holes), confirm the size
with the gasket -manufacturer, as standard items may not be used
When an integral-type flowmeter or a remote type detector is
installed and the pipe carrying higt-temperature fluids is heatinsulated, do not wrap adiabatic materials around the installation
the bracket (DY015 to DY100) or the nozzle (DY150 to DY400) of
the converter.
Flushing of the pipe line:
Flush and clean scale, incrustation and sludge on the inside of
pipe for newly installed pipe line and repaired pipe line before the
operation. For ushing, the ow should ow through bypass-piping
to avoid damaging the flowmeter. If there is no bypass-piping,
install short pipe instead of the owmeter.

*1: To avoid the inuence of external noise, use an electric counter which ts to the pulse frequency.
*2: Resistor is not necessary in case of an electric counter which can receive contact pulse signal directly.
The wiring example for the the simultaneous analog and pulse output, the calculation formula of the
range of load registance R for the pulse output.

Example 1
In this case, Communication
is possible(up to a distance
of 2km when a CEV cable is
used).
When analog and pulse output are used, the length of communication line is subjected to wiring conditions. Refer to
example 1 to 3. If the communication carries out from amplifier, no need to consider wiring conditions.
