DEVICE FOR SF6 GAS DENSITY MEASURING FOR ELECTRIC APPLIANCES AND SWITCHBOARDS

摘要

The gas density, respectively the gas leak is detected by means of one reference tank, to which pressure meter and densimeter are connected. The reference tank is connected, directly or through distributor, with the other tanks that are equipped with pressure meters and reverse valves. The reverse valves are in their reverse direction from the tanks towards the reference tank.<IMAGE>
