2. INSTALLATION

Description

Piping support:

Typical vibration immunity level is 1G for normal piping condition.
Piping support shoud be fixed in case of over 1G vibration level.

Installation direction:

If a pipe is always filled with liquids, the pipe can be installed
vertically or at inclined angle.

Adjacent pipes:

The process pipline inner diameter should be larger than
the digitalYEWFLO inner diameter.
Use the following adjacent pipe.
Norminal size 15mm up to 50mm : Sch 40 or less.
Norminal size 80mm up to 300mm : Sch 80 or less.

Reducer pipe:

Ensure the upstream straight pipe length to be 5D or more, and the
downstream straight pipe length to be 5D or more for per reducer
pipe.
(D: digitalYEWFLO nominal diameter)

Expander pipe:

Ensure the upstream straight pipe length to be 10D or more, and
the downstream straight pipe length to be 5D or more for per
expander pipe.

Bent pipe and straight pipe length:

Ensure the upstream straight pipe length to be 10D or more, and
the downstream straight pipe length to be 5D or more for per bent
pipe.

Valve position and straight pipe length:

■ Install the valve on the downstream side of the flowmeter.
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 straight pipe length.

■ In case the valve has to be installed on the upstream of the
flowmeter, ensure the upstream straight pipe length to be 20D
or more, and the downstream straight pipe length be 5D or more.

Fluid vibration:

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 this 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.

Description

Valve positon (T-type piping exist):

When pulsation causes by a T-type piping exist, install the valve
on the upstream of the flowmeter.
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 fluctuating. To avoid this, change the valve V1
location to V1'.

Pressure and Temperature T aps:

Pressure tap outlet: install this tap between 2D and 7D on the
downstream side of a flowmeter.
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 for certain flange ratings.

Heat-Insulation:

When an integral-type flowmeter or a remote type detector is
installed and the pipe carrying higt-temperature fluids is
heat-insulated, do not wrap adiabatic materials around the
installation bracket 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 flushing, the flow should flow through
bypass-piping to avoid damaging the flowmeter. If there is no
bypass-piping, install short pipe instead of the flowmeter.

(5) Waterproof Construction

The vortex flowmeter is of IP67, NEMA4X
tightprotection. However, it cannot be used under water.

2.4 Piping to Improve Durability

(1) Pipe cleaning

• Flushing of pipe line (Cleaning)
Flush and clean scale, incrustation and sludge on the
inside of pipe wall for newly installed pipe line and
repaired pipe line before the operation.

• Fluid Carrying Solids
Do not measure fluids that carry solids (e.g. sand and
pebbles). Make sure users periodically remove solids
adhering to the vortex shedder.

• Obstruction of flow fluids may cause to make a chemical
reaction and the fluid will be crystallized and hardened,
and be deposited on the pipe wall and shedder bar.
In those cases, clean shedder bar.

(2) Bypass piping

Installing a bypass, as illustrated in the figure below,
permits the digitalYEWFLO to be checked or cleaned
conveniently (vortex shedder, etc.).

Bypass shut-off valve

(1) Installing Cryogenic Vortex Flowmeter

For cryogenic applications, use stainless steel mounting
bolts and nuts to install the flowmeter. These can be
ordered separately from YOKOGAWA. Cover the
flowmeter body with heat insulating material so that the
flowmeter can be maintained at ultra-low temperatures
(refer to the Figure 2.8).

(2) Maintenance for Cryogenic Applications

DY/LT uses special materials that produce vortex
flowmeter for cryogenic applications. When you are
replacing a shedder bar, specify cryogenic type shedder
bar. To avoid condensing in the terminal box, ensure that
the wire connecting port is well sealed.

Installation of the flowmeter is the same as the standard
type. Cover the flowmeter body with heat insulating
material following instruction of “CAUTION”.

CAUTION

Keep the upper limit of heat insulating material to
prevent overheating of the terminal box.

2.6 Installing the Vortex Flow­meter

WARNING

The Vortex Flowmeter is a heavy instrument. Please
be careful to prevent persons from injuring whin it is
handled.

Before installing the instrument verify the following. The
direction of flow should match to the arrow mark on the
instrument body. When changing the orientation of the
terminal box, refer to "7.1."

Installation of Vortex flowmeter of the wafer and flange type
is shown in Table 2.3.

When installing the wafer type vortex flowmeter, it is
important to align the instrument bore with the inner diameter
of the adjacent piping.

To establish alignment, use the four collars supplied with the
instrument.

1. Four collars are supplied for 1/2 inch (15mm) to 1- 1/

2inch (40mm), 2 inch of JIS 10K or ANSI class 150 or
JPI class 150, and 3 inch of ANSI class 150 or JPI class

150. Install the instrument as illustrated in Table 2.2.

2. If the adjacent flanges have eight bolt holes, insert the

stud bolts in the holes on the instrument shoulder. Refer to
Figure 2.9.
Stainless steel stud bolts and nuts are available on order.
When they are to be supplied by the user, refer to Table

2.2 for stud bolt length. Gaskets must be supplied by the
user.

3. Gasket:

Avoid mounting gaskets which protrude into the pipeline.
This may cause inaccurate readings.
Use gaskets with bolt holes, even if digitalYEWFLO is of
the wafer type. Refer to Figure 2.10.
When using a spiral gasket (without bolt holes), confirm
the size with the gasket-manufacturer, as standard items
may not be used for certain flange ratings.

3. WIRING

WARNING

The wiring of the vortex flowmeter must be performed
by expert engineer or skilled personnel. No operator
shall be permitted to perform procedures relating to
wiring.

CAUTION

Once all wiring is complete, check the connections
before applying power to the instrument. Improper
arrangements or wiring may cause a unit malfunction
or damage.

3.1 Wiring Precautions

Be sure to observe the following precautions when wiring:

CAUTION

• In cases where the ambient temperature
exceeds 50°C (122°F), use external heat­resistant wiring with a maximum allowable
temperature of 70°C (158°F) or above.

• Do not connect cables outdoors in wet weather
in order to prevent damage from condensation
and to protect the insulation.

• Do not splice the cable between the flowtube
terminal and the converter if it is too short.
Replace the short cable with a cable that is the
appropriate length.

• All the cable ends must be provided with round
crimp-on terminals and be securely wired.

• Be sure to turn power off before opening the
cover.

• Before turning the power on, tighten the cover
securely.

• Explosion protected types must be wired in
accordance with specific requirement (and, in
certain countries, legal regulations) in order to
preserve the effectiveness of their explosion
protected features.

• The terminal box cover is locked by the clamp.
In case of opening the terminal box cover, use
the hexagonal wrench attached.

• Be sure to lock the cover by the clamp using
the hexagonal wrench attached after installing
the cover.

3.2 Wiring for Output Condition

Table 3.1 shows the connection method of several output
conditions.

(1) Analog Output (4 to 20 mA DC)

This converter uses the same two wires for both, the
signal and power supply. A DC power supply is required
in a transmission loop. The total leadwire resistance
including the instrument load and power distributor
(supplied by the user) must conform to a value in the
permissible load resistance range. Refer to Figure 3.1
shows.

(2) Pulse output and Alarm, Status Output

This version uses three wires between the converter and
the power supply. A DC power and load resistance are
required, and pulse output is connected to a totalizer or
an electric counter. Low level of the pulse output is 0
to 2V. No communication is possible over a transmis­sion line. Communication via the amplifier board is
always possible irrespective of the wiring condition.

(3) Simultaneous Analog-Pulse Output

When using digitalYEWFLO in the simultaneous analog

-pulse output mode, the communicable distance of the
transmission line is restricted on the wiring method.
Table 3.1 shows the examples of connection for this
output mode. Communication via the amplifier board is
always possible irrespective of the wiring condition.

3.4 Wiring Cables and Wires

The following should be taken into consideration when
selecting cables for use between the converter and distributor.

(1) Use 600V PVC insulated wire or equivalent standard

wire or cable.

(2) Use shielded wire in areas susceptible to electrical noise

(both analog and pulse output versions).

(3) In areas with high or low ambient temperatures, use

wires or cables suitable for such temperatures.

(4) In atmospheres where oils or solvents, corrosive gases or

liquids may be present, use suitable wires or cables.

(5) Use cable which withstand temperature up to 60°C and

more, when ambient temperature is more than 60°C.

IMPORTANT

For the remote type, use DYC signal cable to connect
the converter and remote type flowmeter(DY-N).

3.5 Connection of the Remote Type Signal Cable

The remote type signal cable is shown in Figure 3.3 and 3.4,
and the terminal is shown in Figure 3.5.

The maximum cable length is 30 m (97.5 feet).
Remove terminal box cover and wiring connection dust-cap

before wiring.
For remote type the converter has two electrical connections

(cable inlets). Use the left connection as viewed from the
terminal box for the DYC signal cable and the right connec­tion for the transmission cable.

If a signal cable kit is supplied by YOKOGAWA, both ends
of the cable must be finished in accordance with the
following instructions as shown in 3.6.1 and 3.6.2.

3. WIRING

3.7 Wiring Cautions

(1) Lay wiring as far as possible from electrical noise

sources such as large transformers, motors and power
supplies.

(2) It is recommended that crimp-on type solderless lugs be

used for large wire ends.

(3) For general use, it is recommended that conduits and

ducts or racks be used to protect wiring from water or
mechanical damage. A rigid steel conduit or flexible
metal conduit is recommended. See Figure 3.9.

3.8 Grounding

IMPORTANT

When a lightning protector (option code: /A) is
selected, use a grounding resistance of 10Ω or less.

(1) The grounding terminals

outside of the terminal area. Either terminal may be
used.

(2) For pulse output version, ground the flowmeter. Also

ground the shielded cable between the converter and the
pulse receiver.

(3) Grounding should satisfy Class D requirements (ground

resistance 100Ω or less).

(4) Use 600V PVC insulated wire for grounding.

4.6 Operation for HART Commu­nicator

The communication control function with HHT, BRAIN
Terminal (BT200) is stated at 4.5 Operation for the BT200.
digitalYEWFLO is available not only BRAIN Terminal
(BT200) but also HART Communicator as remote control via
HHT.

Main functions and parameters are the same with BRAIN
Terminal (BT200). Moreover, digitalYEWFLO has unique
parameters of HART Communicator.

The amplifier has been pre-configured at the factory, so no
setup should be required prior to installation. If your process
conditions have changed and reprogramming is required, the
menu/parameter configuration list for digitalYEWFLO is in

4.6.12 Menu Tree. Refer to the instructions provided with

your HART communicator for operation details. The QUICK
START section of this manual will address only those
parameters which must be set to establish the operation of the
meter for a particular application. The Menu Tree will cross­reference the BRAIN parameters to the corresponding HART
parameters.

Note: HART is a registered trademark of the HART Communica-

tion Foundation.

4.6.1 Interconnection between
digitalYEWFLO and HART Commu­nicator

The HART Communicator can interface with the
digitalYEWFLO from the control room, the digitalYEWFLO
site, or any other wiring termination point in the loop,
provided there is a minimum load resistance of 230 
between the connection and the receiving instrument. To
communicate, it must be connected in parallel with the
digitalYEWFLO, and the connections must be non-polarized.
Figure 4.6 illustrates the wiring connections for a direct
interface at the digitalYEWFLO site. The HART Communi­cator can be used for remote access from any terminal strip
as well.

4.6.6 Entering, Setting and Sending Data

The data which are input with the keys are set in the HART
Communicator by pressing ENTER (F4). Then, by pressing
SEND (F2), the data are sent to the digitalYEWFLO. Note
that the data are not set in the digitalYEWFLO if SEND (F2)
is not pressed. All the data set with the HART Communicator
is held in memory unless power is turned off, so every data
can be sent to the digitalYEWFLO at one lot.

IMPORTANT

Do not turn off the digitalYEWFLO just after HART
Communicator settings (sending) have been made. If
the digitalYEWFLO is turned off less than 30 seconds
after parameters have been set, the set data will not
be stored and the data returns to previous settings.

Parameters of HART Communicator is constructed hierarchi­cally. The menu tree for Online menu is shown in 4.6.12
Menu Tree.

See 5.4 Parameter Description about the usage of each
parameter. Note the differences between parameters on
digitalYEWFLO display and those on HART Communicator.

■ Check on communication error

When each error, over run framing error, parity error or
buffer overflow error is detected, the data including the
informations of errors is returned, and the error message is
indicated on HHT.

■ Real time monitoring 4-20mA output

‘%’ output, actual flow rate and totalized value are men­tioned as same as BRAIN communicator. And furthermore 4­20mA output is monitored on real time.

■ Time recording

Online ⇒ 1.Device setup ⇒ 4.Detailed setup
⇒ 4. Device info ⇒ 5.Date

F040606_1.EPS

Day, month and year can be set in a number of 2 figures.

■ Multi drop communication

Field devices in multidrop mode refer to the connection of
several field devices on a communication single line. Up to
15 field devices can be connected when set in the multidrop
mode. To activate multidrop communication, the field device
address must be changed to a number from 1 to 15. This
change deactivates the 4 to 20mA output and turns it 4mA
output and turns it 4mA.

■ Multi HHT communication

Corresponding to discriminating communication between two
HHTs.

■ Device ID setting

Device ID is set in an unsigned integer number of 3 bytes.

4.6.9 Data Renewing

There are two methods to load the data of digitalYEWFLO to
HART Communicator, periodic data renewing and discretion­ary data renewing.

(1) Periodic Data Renewing

The following data are renewed in 0.5 to 2 seconds
cycle.
PV, PV % rnge, PV AO, Totl

(2) Discretionary Data Renewing

The following data can be loaded from/to
digitalYEWFLO. Up load can be done with SAVE (F2)
on any online menu, and down load can be done on
Saved Configuration menu in Offline menu. (Refer to
HART Communicator Manual.)

4.6.10Checking for Problems

The self-diagnostic function digitalYEWFLO is stated at
Chapter 6. By using HART Communicator, it is also
available to carry out in “Test/Status” parameter. Exam for
each error.

*Calling up “Diag/Service” setting display.

1.Device setup -> 2.Diag/Service

■ Continuously data returning (Burst mode)

NOTE

In case of using Burst mode, setting from
amplifier unit is not available.

digitalYEWFLO continuously sends the data stored in it
when the burst mode it set “ON”. Either one of instantaneous
flow rate, output in % and current output can be selected and
sent. (Note: This mode is preserved after the converter has
been turned off.)

The interval of sending data in this mode is the same as the
common specification of HART communicator.

6. OPERATION

6. OPERATION

After you have installed the flowmeter into the process piping,
wired the input/output terminals, set up the required
parameters, the vortex flowmeter should output an accurate
flow signal from its terminals as soon as the measured liquid
begins to flow.

This section describes procedure of test method and adjust­ment method for the pre-operation.

6.1 Adjustment

6.1.1 Zero Adjustment

No zero adjustment is necessary since the zero point does not
shift.

Because of the effect of electrical noise and vibration noise,
digitalYEWFLO may provide an output even when the
flowrate is zero. In that case, properly eliminate the source of
the noise.

Refer to “6.2 : Adjustment for manual mode”.

6.1.2 Span Adjustment

In normal application, you need not confirm the span.
If you need to ensure the output of 4 to 20mA DC, refer to

“6.1.3 Loop Test”.

F060101.EPS

IMPORTANT

• When using any test-purpose measuring
instruments, do not ground them.

• All of your parameter settings will be cancelled
if you turn digitalYEWFLO off less than 30
seconds after the parameter setup. Keep
digitalYEWFLO turned on at least 30 seconds
after setting up the parameters.

6.1.3 Loop test

To ensure output of 4 to 20mA DC or pulse, their loop tests
can be done using parameter “J10 (Analog out)” or “J20
(Pulse test)”.

If you are verifying the analog output, follow the procedure
on the verification procedure.

<Check Procedure>

1. Connect the instruments referring to Figure 6.1, and warm
up for three minutes more.

2. Set span frequency in Parameter J10:OUT ANALOG.

3. In case the load resistance is 250 ohm, digital multimeter
indicates 5V. Otherwise if it is known load resistance
value, it indicates R x 0.02A.

4. Check output value after set 50% in Parameter J10.

5. Check output value after set 0% in Parameter J10.

6.1.4 Totalizer Function Start and Total­ized Value Reset

When using the Totalizer Function, the start setup should be
done.

(1) Start operation using BT200

Enter to B40(TOTAL START), and move the video bar
to “EXECUTE”. Push “ENTER” key at 2 times.

(2) Start operation using indicator

Enter to “Setting mode”, move to B40 of parameter
number, and enter to “01” of data number.
Refer to “4.4: Setting mode”.

Totalized value can be reset using the indicator or BT200.
(1) Reset operation using BT200

Enter to B42 (TOTAL RESET), and move the video bar
to “EXECUTE”. Push “ENTER” key at 2 times.

(2) Reset operation using indicator

Enter to “Setting mode”, move to B42 of parameter
number, and enter to “01” of data Number.
Refer to “4.4 : Setting mode”.

6. OPERATION

6.1.5 Unit of Pulse Output (Scaling)

Pulse output are constructed by two units, that are “Scaled
pulse and Unscaled Pulse”.

(1) Scaled Pulse

When SCALED PULSE is selected in B20, set flowrate per
one pulse output. Rate unit is linking to the flow unit.

(2) Unscaled Pulse

When UNSCALED PULSE is selected in B20, it output
number of vortex (vortex frequency) as a pulse-number,
which is detected from vortex shedder bar. (1.0 must be set
for this.)

Refer to 7.6 (1) Flow calculation.

䊉 Pulse Rate setting

Pulse rate setting are settable by “B21:PULSE RATE”.

6.1.6 Power Failure

When a power failure occurs, the totalized value will be
protected by EEPROM (Electrically Erasable Programmable
ROM). But during a power failure, the vortex flowmeter
stops and also the totalizing will stop.

6.2 Adjustment for Manual Mode

digitalYEWFLO does not need the initial adjustment because
digitalYEWFLO is always adjusted by itself automatically.

These adjustments should be done in case that
indicator reads over zero at zero flow.

6.2.1 Low Cut Adjustment

Adjust to noise elimination or zero flow in the low flowrate
(or low frequency) range.
The settable range for low cut flowrate is below half of
minimum flowrate.

6.2.2 Tuning

This adjustment should be done according to a flow figure
shown below.

7.6 Setting Switches

7.6.1 Setting of Burnout Switch

digitalYEWFLO is equipped with a CPU error burnout
function used to set the output direction upon CPU error, and
a sensor burnout function that sets the direction of the output
in the event of burnout of the temperature sensor. When
factory-shipment under normal conditions, the output of both
CPU error burnout and sensor burnout are set to HIGH, but if
suffix code/C1 is specified, the CPU error burnout is set to
LOW(-2.5% below) output, and sensor burnout is set to
LOW(-2.5% below) output, respectively. The setting of the
direction of output from burnout can be changed.

To change the direction of output arising from burnout,
switch the setting pin on the CPU assembly (see Table 7.2).

7.6.2 Setting of Write Protect Switch

By setting the write protect function to “Protect”, it is
possible to prevent the overwriting of parameters. Write
protection can be carried out using either the hardware switch
on the CPU board (i.e., Switch 2) or software parameter
settings. If either of these items is set to “Protect”, the
overwriting of parameters will be prohibited.

If the hardware switch is set to “Protect”, it will
not be possible to overwrite parameters; further­more, this condition will be maintained until the
switch is set to “Enable”.

For more details regarding usage of the write protect function
and the software’s parameter switches, refer to 4.6.11 Write
Protect.

In case of saturated steam, mass flow rate is calculated
from density values to temperature measured by using
saturated steam table.

In case of superheat steam, mass flow rate is calculated
from density values to temperature measured by using
steam table. In order to measure superheat steam, it is
necessary to make constant pressure value. A pressure
values which is entered in parameter is used.

b) Gas

In case of gas, Volumetric flow rate at standard
condition is calculated, so Pressure-Temperature
correction is carried out. It is necessary to make
constant pressure value. A Pressure values at opera­tional condition, temperature and pressure value at
standard condition which is entered in parameter is used.

can result in the leakage of corrosive process fluids and cause injury to
personnel and/or damage to plant facilities. It is also possible that the
instrument itself can be damaged and that fragments from the
instrument can contaminate the user's process fluids.
Be very careful with highly corrosive process fluids such as hydrochloric
acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite, and high­temperature steam (150°C [302°F] or above). Contact Yokogawa for

9. GENERAL DESCRIPTION

■ Pressure Loss

At velocity of 10 m/s by water, ∆P = 108 kPa
At velocity of 80 m/s by atmospheric air,

∆P = 9 kPa
obtained from the following equations.
∆P= 108 × 10

-5

or
∆P= 135 × pf ·

where,

∆P: Pressure loss (kPa )
ρf : Density at operating condition (kg/m3 )
υ : Flow velocity (m/s)

f : Actual flow rate (m

Q
D: Internal Diameter (mm)
Figure 9.5.2 shows pressure loss versus actual flow
rate. When nominal size 15 to 50mm and adjacent
pipeline is Sch 40, and nominal size 80 to 300 mm
and adjacent pipeline is Sch 80, the pressure loss
will be approximately 10% smaller than calculated
value.

(Example) Calculation of pressure loss

Calculate the pressure loss when the nominal size
is 50 mm and the flow rate of water at operating
temperature 80°C is 30m

1. Since the density of water at 80°C is 972kg/m3,
substitute this value in equation (2):

∆P= 135 × 972 ×

51.1

= 17.3kPa

2. Obtain the pressure loss using equation (1). The
flow velocity when the flow rate is 30m

=17.3kPa

3. Obtain the pressure loss using Figure 9.5.2. Since
the liquid pressure loss factor can be read as 18.5,
then:

∆P= 98.1 × 18.5 × 972 × 10

-5

=17.6kPa

■ Cavitation

(Minimum Back Pressure, Liquid service only):

Cavitation occurs when the flow line pressure is low
and flow velocity is high during fluid measurement,
preventing correct measurement of flow rate. The
optimum line pressure can be obtained from the
following equation.
P = 2.7 · ∆P + 1.3 · Po

Where,

P: Line pressure, 2 to 7 times as large as internal

diameter on downstream of flowmeter body
surface. (kPa absolute).

∆P: Pressure loss (kPa).

Refer to the item above.

Po : Saturation liquid vapor pressure at operating

temperature (kPa absolute).

(Example) Confirmation of presence of cavitation

Suppose that the line pressure is 120 kPa abs and the
flow rate scale is 0 to 30 m
confirm the pressure at the maximum flow rate ;
therefore, the saturated steam pressure of water at
80°C is as follows from the table of saturated steam
pressures:
Po = 47.4 kPa abs
Therefore, substitute this value in equation (3):
P = 2.7  17.3 + 1.3  47.4
= 108.3 kPa abs

Since the operating pressure of 120 kPa abs is higher
than 108.3 kPa abs, no cavitation occurs.
