  Douglas Italia manufactures a wide variety of closed sampling systems.
Sampling systems are used into the plants to draw samples of process fluid to be analyzed. It is especially used where the process fluid is under pressure or potential dangerous for human exposure.
Sampling systems can be designed in various materials and pressure rastings in order to satisfied any customer requirement.
   



Operating

Insure that the valve (A) is closed.
Slowly open valves (B) and (C) both pressure gauges should indicate relief header pressure .Disconnect hose at quick connect on inlet manifold.
Place cylinder into cylinder support bracket and slip into the quick connect on the inlet manifold. Connect hose to the upper quick on the cylinder.
Close valve (B) and (C). Open valve (E) and (F).
Slowly open valve (A). Pressure gauge on inlet manifold should rise quickly to operating pressure .Pressure gauge on outlet manifold should follow quickly. If not, line is obstructed and should be safely repaired.
Slowly open valve (C) until pressure gauge on outlet manifold indicates a slightly lower pressure than the inlet manifold pressure gauge. Let sample flow through cylinder for a sufficient amount of time to representative sample.
Close valve (C) and valve (A). Close vale (E) and (F) .
Slowly open valves (B) and (D) both pressure gauges should indicate relief header pressure .Disconnect hose at upper quick connect on cylinder. Remove cylinder by disconnecting quick connect on the inlet manifold. Connect hose to quick connect on inlet manifold so that all circuit will be completely sealed.
Sample shall be taken to laboratory and emptied as soon as possible .Extreme care must be exercised in transportation and storage of full cylinders .
