5-2. Installation (1) Installation location selection The leaked-oil layer will be thinner inversely proportional to increased spread diffusion area. Therefore, it is important to collect the oil in one place. Collecting oil in one place facilitates oil recovery and prevents the spread of disasters, greatly contributing to improved reliability of the detector. - Page 20 (b) Example of installation with the guide attached to the detector Empty pit In case of significant water level fluctuation External flaw 外傷防護 protection Apolarm™ guide bar エポラームガイド 補助フロート Ball float エポラームガイド Apolarm™ guide bar 空ピットアタッチメント Low water guard Fig.5-3 Fig.
- Page 21 (3) Notes on installation [1] Relationship between detection oil layer and oil leak amount at detection The oil leak amount to issue the signal is expressed by the following formula: The oil leak amount at detection = (Detection oil layer of detector) x (Pit surface area). Particularly when installing to an oil-water separation tank or a drainage pit with large surface area, it is necessary to consider partitioning with an oil separator, leading to better practical sensitivity as a result.
- Page 22 [7] Detection oil layer for cable load The cable weight is approx. 100 g/m, and is adjusted to detect 4 mm of kerosene when a load of 1 m is applied. Since the detection oil layer is proportional to the depression amount of the electrodes, the detection oil layer will increase when a load is applied to the float.
