4.3 Limit switches

4.3.1 Options /GM1, /GM2, /GM3, /GM4, /GM5

These limit switches are for RAGK42. It is a reed contact, so if selected the oat must incorporate a magnet. This limit switch is considered as a simple apparatus according to

EN/IEC/ANSI/ISA 60079-11 and therefore does not require a specic hazardous area approval by a notied body. A self-declaration regarding the compliance to EN 60079 is available on the Flow Center Pages: RAGK_RAGN_Ex_Declaration_Option-GMx.

The /GM can be used together with a power supply option /WA or /WB.

The back panel of the meter has an opening for proper mounting of the contact.

Rotameter RAGN option /GRx (x = 2 ... 8)

4.3.2 Options /GR1, /GR2, /GR3, /GR4, /GR5, /GR6, /GR7, /GR8

These ring initiators are for RAGK41 and for RAGL41. These are inductive bipolar limit switches, which means that the oat must have ferromagnetic features. The matching oat must therefore be made from Mu-metal.

The /GR can be used together with a power supply option /WA or /WB.

The ring initiator is mounted directly over the tube, so the protection cover is not possible. By its design the ring initiator is sensitive to strong electromagnetic impulses, so installation should be

on sufficient distance from such sources.

4.4 Hazardous area approvals

Hazardous area approvals ATEX(/KS1) and IECEx(/ES1) are available for inductive ring sensor options /GR. The certicate can be found on the Flow Center pages: RAGK_RAGL_RAGN_Cert_ATEX_RI20_Option-GR_E, RAGK_RAGL_RAGN_Cert_IECEx_RI20_Option-GR_E.

4.5 Scale types

The offered scale types for RAGL and RAGK have the following characteristics:

A Fluid spec. attached scale, blank tube high high ---- yes

N mm- scale, sticker scale on tube middle middle high no

with

option /IB

Exchangable

4.5.1 Scale types G and N

If the atmosphere is very aggressive and the user might have concerns about the chemical resistance of the sticker scale, option /IB is very suitable. With option /IB the scale will be directly printed and burned in on the tube. The burned in scale will be printed permanently on the tube and cannot be exchanged. For normal atmosphere the sticker scale is completely sufficient. The scale type A can be combined with the scale types G and N. In combination with /IB, scale types G or N are replaced by the burned-in scale.

4.5.2 Dual scale types, suffix code D and F

If two different uids run through the meter or if two quite different process conditions exist (more typical for gas), two different scales can be provided with the meter.

With suffix code F only one scale design is sufficient. In this case the attached scale will be engraved with the uid specic data, whereas the mm scale is fastened on the tube.

With suffix code D, two different sets of process conditions and scale designs must be delivered as ordering instructions to the manufacturing. The rst scale design (a) is fastened as a sticker on the

TI 01K01B04-01EN-R: 1st edition, April 01, 2020-00

tube, the second scale design (b) is engraved in the attached scale. To generate the 2 sets of ordering instructions in the FlowCongurator and SAP proceed as follows:

• Size rst the uid for the (a) scale

• Press “Export ordering instruction for YGS” and store the le ((a) scale)

Fig. 12 Window Ordeing Instruction, FlowCongurator

• Note the Model Code from the rst sizing.

• Start a second sizing. Make sure by varying the second max ow range, that you get the same model code. If the second sizing gets a different cone, the instrument is physically not producible. If the uid data and ow ranges of the two uids are too different, a dual scale may not be possible.

• Press “Export ordering instruction for YGS (dual scale)” and store the le ((b) scale).

• Import the model code in SAP and upload (a) scale rst and then additional the (b) scale as ordering instructions with the same upload function.

4.6 Test and Certicates

4.6.1 Option /H1: Oil and fat free for wetted surfaces according Yokogawa specication

For specic description, please see document TI 01K01B03-01EN-R.

4.6.2 Option /P2: Certicate of compliance with the order acc. to EN 10204: 2004-2.1

At the nal check a test will be processed which guarantees the compliance with the order. This compliance is guaranteed with a certicate. An example can be found on the Flow Center page: RAGK_Cert_example_2-1 compliance with the order_E_D.

4.6.3 Option /P3: As /P2 + Test report acc. to EN 10204: 2004-2.2

The protocol of the test will be delivered additional to the certicate. An example can be found on the Flow Center page: RAGK_Cert_example_2-2_test_report_E_D.

4.6.4 Option /PP: Pressure test report for measuring system

The instrument is pressurized with factor 1.6 above its nominal pressure (burst pressure test) and is inspected for tightness. A result report regarding the test is delivered. An example can be found on the Flow Center page: RAMC_Cert_PP_Pressure test report Certicate Example.

TI 01K01B04-01EN-R: 1st edition, April 01, 2020-00

4.6.5 Option /PT: Flow table for recalculation to other uid

In case of scale N and F, only mm graduation is on the tube. To “translate” the height in mm in ow units, a recalculation table is required. This table shows the uid data the Rotameter is sized with. On the left side of the table you nd the height of the oat in mm and the calibration conditions, and on the left side the process uid.

Fig. 13 Sample of ow table

4.7 O-Rings

The small glass Rotameter are in standard equipped with Viton O-rings. However if other O-ring material is requested, /NBR (NBR, trivial names: Buna or Perbunan) or /KAL (Kalrez) can be selected. For RAGK O-rings are used in the valve and for the sealing of the tube. For RAGL O-rings are only used in the valve. The tube is sealed with a PTFE press tting.

4.8 Float stop

The standard oat stoppers are made from PTFE. The standard oat stoppers can be exchanged with spring SS stoppers via option /S1.

4.9 Accessories

4.9.1 Option /QP: means for panel mounting

At customer site, a suitable slot must be machined in the panel. The size of the slot is given in the GS.

Fig. 14 RAGK with option /QP Fig. 15 Panel mounting

Two of the parts marked in the drawing (see Fig. 15) with the “X” are delivered with the instrument. The parts are inserted from the front as shown in the slot. The instrument is moved between the parts and fastened with the 4 cross-head screws. Then the total construction is xed with the 2 long screws from the back side at the panel.

4.9.2 Option /QB: With tapped holes in the connecting heads for mounting

These holes for M3 screws are for example used for the foot stand or to screw the means for the panel mounting. They are offered for the case that the customer wants to establish his own xing of the instrument. The detailed dimensions are given in the GS.

4.9.3 Option /QF: Foot stand

One possibility to x the instrument. The foot stand incorporates a level for proper adjustment of the instrument. See also drawing in the GS

4.9.4 Option /QC: Colored caps for valve knob (red, blue, yellow, green)

The valve knob has a removable cap for mounting. Normally it is black. This option provides a small plastic bag with 4 caps in the colour red, blue, yellow, green to mark the valve knob. So in a row installation different uids can be high visible marked by the colour of the knob cap.

4.12.1 Option /QR: Primary Verication for Russia

The calibration certicate is sent to a notied body registered in Russia together with a technical passport.

The calibration rigs of RYG are approved by this notied body to be sufficient to do the primary verication. The notied body checks the calibration certicate and conrms the primary verication with a stamp in the technical passport. The technical passport is resent to Rota Yokogawa and later delivered with the instrument.

4.13 Power supply

The power supplies for the limit switches can be ordered with option /WA or /WB. These are available with one or two channels.
