Abstract

PURPOSE:To ensure an accurate detection for leakage of a storage tank without receiving any effect of evaporation of the liquid in the tank, by inserting the reference pressure setting mechanism into the tank storing the liquid and detecting the change of difference between the pressure within the tank after reduction of pressure and the reference pressure. CONSTITUTION:Both the ventilation tube 2 and oil supply tube 6 linked to the storage tank are closed, and a part of the liquid in tank 1 is removed via the suction tube 4 while looking at the barometer 14. In this case, the valve rod 18 of the reference pressure setting mechanism 9 attached airtight to the counter tube 8 of tank 1 is pulled up by the operation lever 20 against the spring 19, and the pressure is reduced in the state under which the hole of the bottom plate 16 is opened with a part of the liquid put into the reference tank 10 and the hole of plate 16 is closed via the valve 17. The change of pressure difference is detected by the differential pressure gauge 12 connected to both tanks 1 and 10. In such way, the leakage of tank 1 can be detected accurately without receiving any effect of evaporation of the liquid 7 stored in the tank 1.
