•Piping for Avoiding Bubbles

Flows containing both gas and liquid cause problems. Avoid gas bubbles in a liquid flow. Piping should be carried out to avoid bubble generation.

Install the valve on the downstream side of the flowmeter because pressure drop across the control valve may cause gas to come out of the solution.

(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.).

2.5Cryogenic and High process Temperature Version Insulation

When you are using cryogenic type and high process temperature version of digitalYEWFLO Vortex Flowmeter (Option code/HT /LT), refer to illustrated insulation method as shown in Figure 2.8

2. INSTALLATION

(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.

2.6Installing 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 heat-

resistant 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.

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).

3.5Connection 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.

CAUTION

After completing the signal cable connections, install the shielded cover to signal cable terminal as shown in Figure 3.6.

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 are located on the inside and 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.

4.2 Display Contents in Display Section

The display content items are classified in the following three items.

Table 4.2		Mode Name List
	Mode (status) Name		Display Contents
	Flowrate display		A mode in which instantaneous flow rates or totalized values are displayed.
	mode		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 confirmed 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		This mode is overlapped when an alarm is occurring in display mode. The alarm number presentation to
	mode		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.
