2. Design and function
2.1 Description
The EMICOgauge instrument hook-up, consisting of pressure gauge and instrumentation
valve, minimises the number of leakage points and thus reduces the risk of media escaping
into the environment.
The valve bonnets of the EMICOgauges are marked with an orange ring in addition to the
coloured dust cap.

EMICOgauge connection with 360° swivel connection
Instrumentation valve, model IVM, double-block-and-bleed, instrument version
Cone for metal-to-metal seat
O-ring sealing
Support ring
The 360° swivel adapter connection of the EMICOgauge enables quick alignment of the
pressure gauge with simultaneous pressure sealing. In addition, this makes it easy and
safe to disassemble the EMICOgauge into pressure gauge and valve. See chapter 7.2
“Separation at the EMICOgauge connection”.

Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious injury
or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries or
damage to property or the environment, if not avoided.
WARNING!
... indicates a potentially dangerous situation that can result in burns, caused
by hot surfaces or liquids, if not avoided.
Information
... points out useful tips, recommendations and information for ecient and
trouble-free operation.
3.2 Intended use
The EMICOgauge instrument hook-up is used to measure pressure in the process indus-
try. Using the shut-o and venting function(s) of the instrumentation valve, the measuring
instrument can be safely separated from the process. Due to conformity with TA-Luft
(VDI 2440), there is a signicantly reduced risk of fugitive emissions. This is also ensured
by the EMICOgauge connection, a 360° swivel connection (swivel adapter) with a special
pressure sealing.This connection enables easy replacement and the positioning of the
measuring instruments at the measuring location.
The EMICOgauge is only suitable for gaseous and liquid aggressive media that are not
highly viscous or crystallising.
The maximum permissible operating pressure of the EMICOgauge is determined by the
component(s) having the weakest performance data.
3.3 Improper use
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
▶
Refrain from unauthorised modications to the instrument.
▶
Do not use the instrument within hazardous areas without suitable appro-
val.
▶
Do not use the instrument with abrasive or viscous media.

14525888.01 04/2022 EN/DE/FR/ES
WIKA additional operating instructions for EMICOgauge
Any use beyond or dierent to the intended use is considered as improper use.
Do not use this instrument in safety or emergency shutdown devices.
3.4 Responsibility of the operator
Due to the redundant pressure sealing of the EMICOgauge connection, up to 20 mounting
and dismounting operations of the pressure gauge can be carried out. See chapter 7.2
“Separation at the EMICOgauge connection”. After that, the operator is obliged to use a
new EMICOgauge instrument hook-up, so that the leak tightness of the overall system can
be guaranteed.
Systematically record mounting and dismounting operations at measuring
locations with EMICOgauges in order to be able to plan replacement of the
instrument in good time.
The legibility of the marking must be observed during time in use but at least during inspec-
tion periods of three years. If any harm of the legibility is found please contact the manufac-
turer to renew the marking.
3.5 Personnel qualification
WARNING!
Risk of injury should qualication be insucient!
Improper handling can result in considerable injury and damage to property.
▶
The activities described in these operating instructions may only be
carried out by skilled personnel who have the qualications described
below.
Skilled personnel
Skilled personnel are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowled-
ge of country-specic regulations, current standards and directives, are capable of carrying
out the work described and independently recognising potential hazards.
3.6 Labelling / Safety marking
Pressure gauge and instrumentation valve are marked in accordance with the documenta-
tion supplied, depending on the version.The text “EMICOgauge” is shown on the dial.

4. Transport, packaging and storage
4.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
CAUTION!
Damage through improper transport
With improper transport, a high level of damage to property can occur.
▶
When unloading packed goods upon delivery as well as during internal
transport, proceed carefully and observe the symbols on the packaging.
▶
With internal transport, observe the instructions in chapter 4.2 “Packaging
and storage”.
4.2 Packaging and storage
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +70 °C [-40 ... +158 °F]
■
Protect the measuring instruments from humidity and dust!
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Hazardous environments, ammable atmospheres
WARNING!
Before storing the instrument (following operation), remove any residual
media.This is of particular importance if the medium is hazardous to health,
e.g. caustic, toxic, carcinogenic, radioactive, etc.

5. Commissioning, operation
Only use original parts.
WARNING!
Physical injuries and damage to property and the environment caused
by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, ammable
or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic,
radioactive), and also with refrigeration plants and compressors, there is a
danger of physical injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high temperature
and under high pressure or vacuum may be present at the instrument.
▶
For these media, in addition to all standard regulations, the appropriate
existing codes or regulations must also be followed.
▶
Wear the requisite protective equipment
5.1 Mounting at the process connection
■
When unpacking, check all components for any external damage.
■
Ensure that all unused connections are closed. Plug screws for vent connections are
included in delivery, though not pretted.
■
The EMICOgauge must only be carried by the valve body, and not by the valve handles
nor the pressure gauge case.
■
Check the product marking for correctness (see chapter 3.6 “Labelling, safety marking”).
■
Before mounting, ensure that the process line has been depressurised using the main
valve.
■
Remove the protective cap of the process connection.
■
Ensure that the sealing faces are clean and do not show any mechanical damage.
■
The correct sealing element must be used for the respective connection.
Threaded connection
To screw in threaded connections the appropriate tool must only be applied through the
spanner ats provided for this purpose.
The tightening torque is dependent on the process connection and sealing element used.
Flange connection
The ange standard (e.g. ANSI B16.5 or EN 1092-1) for mating anges and mounting
elements (sealings and stud bolts) must match the EMICOgauge supplied. Before
mounting, the mating anges and mounting elements must be checked for correct size and
nominal pressure rating.

WIKA additional operating instructions for EMICOgauge
5.2 Commissioning and operation
To close the valve, turn the handle in a clockwise direction as far as the stop.To open the
valve, turn the handle anticlockwise as far as the stop. It will take approximately 4 turns
from open to closed and vice versa.
The ow can be controlled by not totally opening/closing the valve.
Please note that the handle may present a slight play and spin freely up to a
quarter turn when in the depressurised state.This is due to the constructive
design.
■
The valve, especially the handle, must not be subjected to any external loading (e.g. use
as a climbing aid, support for objects).
■
The handle may only be used by hand; the use of tools is not accepted.
■
The torque on reaching the valve stop must only be hand-tight.
■
Ensure that all valves of the product are closed prior to opening the main valve of the
process line.
