Fuel Tank Preparation
1. Select the location for Omnicomm LLS sensor installation, taking into account the following requirements:
- The installation location should be as close to the geometric center as possible and be placed at the deepest level of the tank:
- When installed, the sensor should not be in contact with reinforcement ribs and existing equipment inside the tank
- Installing two sensors in one fuel tank allows to significantly reduce the influence of the vehicle inclination angle on the fuel level:
2. Steam out the tank to comply with safety regulations
3. Drill out the central bore using a bimetal hole saw ø35 mm
4. Drill out four mounting holes according to the diagram:
The mounting hole diameter depends on the material of the tank:
- ø 4 mm – for metal tanks with wall thickness over 3 mm (cut M5 thread)
- ø 7 mm – for plastic and metal tanks with wall thickness up to 3 mm (for rivets)
- ø 4 mm – for plastic tanks with wall thickness over 3 mm
1. Cut the sensor measuring part according to the following recommendations:
- The length of the sensor measuring probe should be 20mm less than the depth of the tank.
- The REF channel must be at least 100 mm shorter that the measuring part of the sensor. If the difference is less than 100 mm, trim the REF channel according to the figure:
2. Install the central partition into the sensor measuring part at the depth of 1 cm.
Cut the REF channel (only if the length of the REF channel and the measuring part is less than 100 mm):
1. Install the central partition in the REF channel in close proximity to the cut point.
2. Cut with a cutting wheel (max. 125 mm in diameter)
3. Remove a section of the REF channel rod
The REF channel rod is shorter than the main measuring rod and is located on the right when looking at the sensor body on the connector side.
