6.1 Type of fuel The sensors shall be required to measure the level of diesel fuel in the locomotive mounted tank.

6.2 Mounting arrangement of sensors The fuel tanks used on the diesel-electric locomotives of the Indian Railways are primarily manufactured as per the drawings listed in the following paragraphs. The 3D Model of the different fuel tanks used in the diesel locomotive is attached at Annexure-7.

Note: The location of other locomotive mounted equipment governs the accessibility of the fuel tank for mounting of the sensors. Therefore proper selection of the mounting options is required for assessing suitability of mounting arrangement based on the locomotive class and the onboard equipment.

From the different arrangement of tanks and the options of locomotive mounted equipment, it is understood that non-invasive fuel level sensor will be suitable for mounting on the fuel tank. However, invasive fuel level sensor is also permitted provided the same can be fitted with least modification in the fuel tank during retrofitment and does not require dismantle of fuel tank from locomotive.

The mounting arrangement with required modification in fuel tank needs to be approved by RDSO before fitment.
