Preparation
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 de-pendence of the fuel level on the vehicle inclination angle:
2. Steam out the tank to comply with safety regulations
3. Drill out the central bore using a bimetal core drill (or 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
Sensor Preparation
- Measure the depth of the tank. Cut the sensor measuring piece so that its length is 20mm less than the depth of the tank. Ensure that the shearing line is perpendicular to the sensor's longitudinal axis
- Use oil-and-petrol resistant non-conductive sealant to fill the insulation cap (included in the kit) to 1/4–1/5 of its volume. Recommended sealants: PERMATEX™ MotoSeal® Black, ABRO™ Black, ABRO™ Red
- Put the insulation cap on the central rod of the Omnicomm LLS sensor
