Figure 1. Dosaodor DO200 Injection Panel and Control Panel
Only qualied and instructed personnel can install and handle the odorant tank.
The odorizing system must be installed, operated and maintained in accordance to all applicable rules and standards.
Follow the instructions, especially the ones relevant to “pressure risk”.
The installation, operation and maintenance procedures, if not performed by qualied personnel, can be dangerous.
These circumstances can lead to damage to the devices, injuries to people or damage to properties due to gas or liquid leakage. If there is a leak in the system, the released
gas can accumulate and provoke res
or explosions.

WARNING
!
Dosaodor DO200
Explosions of parts under pressure can occur if the system is installed where its operating conditions (PS and TS) can be exceeded or where service conditions can
exceed the limits of the piping or
its connections.
Call immediately qualied service personnel in case of any issue.
In order to avoid these conditions, install the device in a safe place, where it is protected to the exposure to damage and/or corrosive substances, and where operating conditions
are within the limits of the device
(the product cannot be exposed to operating conditions different from what it has been designed for).
Do not exceed the pressure nominal values of the single components of the system.
INTRODUCTION
Scope of the Manual
This manual provides installation, start-up and maintenance instructions for the Dosaodor DO200 odorant injection system. Information on the other equipment used with DO200 is found in separate manuals.
PRODUCT DESCRIPTION
The Dosaodor DO200 is a Smart odorant system for natural
gas, that injects odorant proportional to the ow rate of
the gas in transit. The Dosaodor DO200 is completely
congurable and can interface with remote monitor and
control system.
The system can be congured to use redundant injectors
and/or emergency absorption system. The equipment consists of a injection panel to be installed in
the hazardous area and a control panel to be installed in the safe area, interconnected by electric cables.
Benets:
• Operational safety
• Extreme reliability
• Very low maintenance
• Ease of use
• Results certainty The system does not us any dosing pumps to inject the
odorant liquid in the downstream pipelines, it uses the natural gas differential pressure, which is always present between the upstream and downstream sections of a reduction and metering gas station (minimum 1 bar) and an electrically controlled panel unit certify according to the ATEX international directive. In case 1 bar differential pressure is not present, it can be used methane or nitrogen
cylinder pack to inject the odorant liquid downstream.
The injection panel is made of stainless steel, without a painted nish, or screen printing as odorizing liquids are aggressive.
Before any scheduled or unplanned maintenance, the
system can be cleaned from odorant by performing a simple procedure that push the odorant inside the injection panel
into the main odorant tank.
This allows the operator to perform the maintenance in an easier and safer way.
A pressure differential level transmitter measures in real time the quantity of liquid injected into the pipe, while the control panel automatically adjust the dosing rate depending on the odorant quantity injected, measured by the level transmitter,
compared to the instant natural gas ow rate (measured by a ow meter, or sent by a ow computer).ensuring great
system reliability and overall accuracy. The same differential pressure transmitter measures in
real time the odorant level from the main tank, allowing an easily planning of the rell activities, providing the necessary information for the relling of the tank.
Optionally the injection panel can be equipped with two
injection valves, one for high (H) and one for low (L) ow
rates. The system can automatically switches between the injector
valves based on the programmed data and current ow rate.
The system ensures the dosing rate while keeping the
desired odorant concentration level steady with over the
entire ow range of the system, even when the ow is
extremely variable and extremely low. This particular feature guarantees high safety within the
sphere of the natural gas distribution for public use. In fact, by maintaining a constant level of odorant concentration not
matter what the gas ow rate, any leakage of gas can clearly be identied reducing the possibility of accidents.
In addition to this, recorded reports of the gas volumes, and the quantity of odorant emitted, allow gas grid operators the
data for conrming the correct operation of the gas systems.
2
In the event of malfunctioning or power outages, the control panel saves the programming data by means of a buffer battery and sends out a signal to activate any emergency devices (it normally restarts operation of the absorption-type emergency system).
The Dosaodor DO200 complies to UNI-CIG 9463.
Dosaodor DO200
Absorption System
The absorption type backup system is constituted by a
pneumatic valve actioned by a solenoid valve, both installed
on the piping spool between the odorant tank and the main gas line, downstream the ΔP valve.
When the absorption system is activated, the pneumatic valve actioned by the solenoid valve opens ensuring gas
ow through the tank, due to the differential pressure created on the gas main line by a dedicated valve (buttery or ball
valve depending on the operating pressures of the reducing station).
The gas, being in contact with the surface of the odorant
liquid inside the tank, gets soaked with the same liquid, going back to the main line properly odorized.
The regulation of the gas ow is performed through the needle valve installed on the tank.
The setting of the absorption system is xed; it is therefore
necessary to modify it in case of a change in the operating conditions.
The absorption system tank is also used as service tank
for the main injection system, ensuring, during normal functioning, the feeding of liquid to the injection panel.
The following accessories are installed on the tank:
• Level indicator
• Inlet needle valve
• Outlet valve
• Odorant loading valve
Tank pressure gauge
• Liquid feeding assembly to the injection panel
• Collection basin
Double Injection System
As emergency system, instead of the absorption system, a second Dosaodor DO200 can be foreseen.
The system Injection + Injection works exactly like the system Injection + Absorption type; in this case the backup
is ensured by the second Dosaodor DO200.
In this conguration, instead of one injection panel, two
identical ones (Master / Slave) will be installed. In case of malfunctioning of the main panel, the second one will be
activated and will work in the same way.
The selection between Master or Slave system is done through a dedicated switch.
Both systems will have dedicated power feeding and auxiliary batteries pack (optional).

ATEX REQUIREMENTS
According to the following documents:
• I-N97 CEN/SFG-I “ATEX-Guidance Sheet (ATEX Guideline of Sector Forum Gas - Infrastructure)”
• FAREGAZ Position on ATEX Topics,
The Dosaodor DO200 injection system is classied as
“Installation” according to chapt. 5.2.2 of “ATEX Guide Lines
4.a Edition - September 2012”, therefore it’s not included in
Directive 2014/34/UE (ATEX I). ATEX devices that are included in Dosaodor DO200 system
must be Ex-certied.
Dosaodor DO200 system must comply to Directive 1999/92/EC (ATEX ll) and the other applicable National standards.
Odorizing systems (absorption and/or injection types) are designed as independent installations or as part of pressure reducing stations (ref.: EN 12186).
Dosaodor DO200 is sold on the market with all its complementary parts, like for example the bypass for
activating the absorption type system, the material for electric installation and all the other components to be properly installed on site.
INSTALLATION
General Rules
WARNING
!
National safety standards must be followed for the installation and operation of odorizing systems, in particular for the electric connections, re and lightning protections,
and for the procedures of odorant
liquid handling.
All ventilation means must be supplied in the pressure reducing stations where the pressure equipment is installed.
Before the installation, check that operating conditions are suitable with the limit ranges.
For odorant tank installation:
Foresee an adequate cathodic protection
and electric isolation to avoid any corrosion.
Gas must be cleaned through dedicated
lters/separators/dust collectors to avoid any risk of erosion or abrasion in the parts under pressure.
The technical reference standards are released at National level (in Italy: UNI 9463-1 and 9463-2), but odorizing systems must be installed under the responsibility of the
user after completing the risk analysis (dangerous areas classication, etc.) and, during the start-up, also the testing
and necessary set-ups are realized under the user responsibility.
TRANSPORT AND HANDLING
Suitable and consolidated procedures for transportation and handling have to be adopted in order to avoid any damage to the devices under pressure due to abnormal stress.
The product can be lifted and positioned with standard lifting
devices. A special care has to be taken to avoid any damage
to installed accessories.
STORAGE
The Dosaodor DO200 is supplied with all the surfaces completely protected (painted or in stainless steel), so it
does not require special precautions for the storage; it is
enough to follow some recommendations. At its arrival on site, the product has to be completely
inspected to check any possible damage caused by the
transport. Inspect also the conditions of the pressure accessories that are installed (valves, level indicators, etc.).
COMPONENTS POSITIONING
Control Panel
To be installed in an electrically “Safe” area. Therefore, in natural gas decompression plants, the facilities suited to these purposes are the following:
Electric power facility, a dened area designed and built
to house all electrical devices linked to and controlled by
the station. i.e. Flow computers, remote monitoring units, telephones, etc.
Heating plant, that is, a dened area designed and built to house the boilers needed for the heating of gas. This area
must be built and installed according to the specications for an electrically “Safe area” classication.
• Rooms and storage units located outside the areas
dened as “Hazardous areas” according to the actual
regulation.
It is recommended that the control panel installation guarantees an easy opening of main door.
It is best to install the unit is in the immediate vicinity
of the ow computer, to facilitate the connection of the
cable receiving signals from the Dosaodor DO200 during operation.
Ground connections of the electronic control unit and shielded cables to must be connected an equipotential node (mandatory only for the countries members of the EEC).

Injection Panel
To be installed in the immediate vicinity of the odorant
pick-up point (absorption-type tank or other type of tank).
All its components can resist to the chemical attack of all odorant liquids and the aggression of atmospheric agents; it
has to comply with the requirements to guarantee electric safety.
WARNING
!
The injector has to be installed on the downstream piping of the station. It is important to minimize the distance between panel and injector, as a short distance limits the quantity of odorant under pressure,
reducing the possibility to have liquid
micro leaks.
The panel, in its standard version, is designed for oor installation; upon request, a support can be supplied for wall installation.
It is very important to check that the lowest point of the tank from which the odorant is picked up (bottom) is located at a height of at least 50 cm from oor level, and that the panel is positioned with the lower anchoring brackets resting on the oor. Lower height between 40 cm and 50 cm shall be evaluated punctually based on the instantaneous gas ow rates.
For wall installation (optional), two spacer brackets are
supplied to install the panel at a certain distance from the supporting wall.
The Dosaodor DO200 system includes an accessory kit
necessary for the standard installation of the system. For the installation of the optional absorption type system refer to Figure 6.
COMPONENTS CONNECTIONS
Electric Connections on Site
Figure 14. Electric Connections
The junction box S, installed on the injection panel, collects all the signals (input and output) present on site. Inside the box there is a terminal for the connections, with numbered clamps and ground clamps.

odorants.
WARNING
!
The piping connecting the Dosaodor DO200 panel with the odorant tank has to be shaped in a way to avoid air/gas pockets, therefore it is suggested to make it as straight as possible and with a constant slope, with absolutely no rises and descents.
