The System operates by liquid- Injection and it can be installed in combination with traditional absorption-type devices. The DOSAODOR-D System is completely configurable and can also be interfaced with remote monitoring systems.

8 The equipment consists in a pneumatic panel to be installed in the hazardous area and a microprocessor electronic control unit to be installed in the safe area, intercon-nected by electric cables. The System ensures the dosing rate while keeping the desired Odorant concentration level steady with any gas flow rate of the station, even when the latter is extremely variable and extremely low. This particular feature translates into a marked increase in safety within the sphere of the distribution of natural gas for public use. In fact, by maintaining a constant level of the concentration in all of the gas flow rates being supplied, any leakage of gas can clearly be identified, thereby decreasing the possibility of accidents.

9 In addition to this, the possibility of having printed reports on the gas volumes, the amounts of Odorant emit-ted and the concentrations thereof, provides facility managers with objective aids confirming the proper functioning of their objectives obtained with this new System can be summarized as follows: Operational safety Extreme reliability Low maintenance requirements Simple use Dependability of the resultsThe System does not involve the use of dosing pumps or other complex devices for the measurement of Odorant flow rates. The System uses the differential pressure, which is always present between the upstream and downstream sections of a reduction and metering gas station (min.)

10 1 bar), and an electrically controlled Injection unit that has been designed and certified in accordance with international standards for electrical equipment in EEx areas with risk of explosion. The DOSAODOR-D utilizes the high-pressure upstream gas as the pneumatic driving fluid in order to inject the odorizing liquid in the downstream pipelines, creating a gas driven pump. The pneumatic panel is made of stainless steel without a painted finish or screen printing as odorizing liquids are aggressive. A procedure has been designed to perform the decontamination of the entire Injection circuit.
