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 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 ﬂ 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 ﬂ 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 ﬂ 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 ﬂ owmeter. Drain it appropriately.

WARNING

The wiring of the vortex ﬂ owmeter 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.

4.1 Load Resistance of Output Condition

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 ﬂ owtube 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 speciﬁ c 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 Locking Screw. In case of opening the terminal box cover, use the hexagonal wrench attached.

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

Table 4.1 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 4.1.

(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 ampliﬁ er board is always possible irrespective of the wiring condition.

4.2 Selection of 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 ﬂ owmeter(DY-N).

4.3 Connection

(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

4.1 shows the examples of connection for this output mode. Communication via the ampliﬁ er board is always possible irrespective of the wiring condition.

IMPORTANT

For pulse output and the simultaneous analogpulse output ,use the load resistance. Refer to Table 4.1.

(5) Perform attachment of ﬂ ameproof packing

adaptor in the following ways. Refer to Figure

4.11.

(a) Loosen the locking screw and remove the

terminal box cover.

(b) Measure the cable outer diameter in two

directions to within 0.1 mm.

and use packing with an internal diameter nearest to this value. Refer to Table 4.2.

(d) Screw the ﬂ ameproof packing adapter into

the terminal box until the O-Ring touches the wiring port (at least 6 full turns), and ﬁ rmly tighten the lock nut.

(e) Insert the cable through the union nut, the

B. coupling, the clamp nut, the clamp ring, the packing gland, the washer, the packing, and the packing case, in that order.

(f) Insert the end of the cable into the terminal

box.

(g) Tighten the union cover to grip the cable.

When tightening the union cover, tighten approximately one turn past the point where the cable will no longer move up and down. Proper tightening is important. If it is too tight, a circuit break in the cable may occur; if not tight enough, the ﬂ ameproof effectiveness will be compromised.

(h) Fasten the cable by tightening the clamp

nut.

(i) Tighten the lock nut on the union nut. (j) Connect the cable wires to each terminal.

(6)

(a) Do not connect cables outdoors in wet

weather in order to prevent damage from condensation and to protect the insulation.

(b) Do not splice the cable between the

ﬂ owtube terminal and the converter if it is too short. Replace the short cable with a cable that is the appropriate length.

separate steel conduit tubes 16 (JIS C

8305) or ﬂ exible conduit tubes 15 (JIS C

8309).

(d) Always route the power and output signal

cables in separate steel conduit tubes, except when the power supply voltage is 24 V and four-core cables are used for wiring. Keep conduits or ﬂ exible tubes watertight using sealing tape.

(7) For the TIIS ﬂ ameproof type with wiring using

a ﬂ ameproof packing adapter, wire cables through the packing adapters approved by Yokogawa (option code: /G11 or /G12).

4.7 Grounding

IMPORTANT

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

(1) The grounding terminals

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

(2) For pulse output version, ground the ﬂ owmeter.

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

(3) Grounding should satisfy Class D requirements

(ground resistance 100 or less).

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

5.2 Display Contents

The display content items are classiﬁ ed in the following three items.

Table 5.1 Mode Name List

Mode (status) Name Display Contents

Flow rate display mode A mode in which instantaneous ﬂ ow rates or totalized values are displayed.

Display content is usually selected either in display content selection mode or by setting parameters via BRAIN communication.

Setting mode In this mode, parameter contents are conﬁ rmed or data is updated using the setting section. The

mode is changed to this mode when “SET” key is pressed in normal mode.

Alarm number display mode This mode is overlapped when an alarm is occurring in display mode. The alarm number

presentation to indicate alarm contents (about 2 sec) and the normal data display (about 4 sec ) are repeated alternatively.

Mode represents that the system is in a state where the relevant setting or display is possible.
