Gas detection system 33200

33200 GAS ELIMINATION DEVICE Double acting pneumatic pumps, for the mounting directly in 208 l – drums or as wall-mounted pump kits with air separator kit (with automatic pump stop, stopping the pump as soon as air is sucked into the suction line due to an empty drum or tank) according to OIML R117-1, approved for the use in fiscal transactions. The system intercepts any air accidentally sucked up by the pump and acts by shutting down the system. The accidental suction of air can occur when there is no liquid present in the feeder tank: in this case the pump begins to suck air into the instrument, but it is intercepted by the system and discharged into the suction tank while the command to stop the pump is activated. In this way the section of the instrument between the interception system and the flow meter remains completely free of air and contains only oil. After the pump has been shut down and the required oil suction reset (for example to allow replacement of the drum or refilling of the tank), the system can be restarted by pushing a button that initiates a complete purge of air from the instrument and reactivates the normal working conditions of the system.
