Recommended Configuration for Galooli Gateways
Fuel sensor range calibration - Omnicomm Configurator download link
Upon opening the configuratorGalooli uses the Omnicomm capacitive fuel sensor to read fuel data directly from the fuel tank. Any other fuel sensor utilized by the customer will not be supported by Galooli.
| Info |
|---|
Fuel sensor installation requires direct access to the fuel tank. Therefore installation of fuel sensors can be attempted only with large vehicles that provide direct and secure access. |

Physical Installation
Step 1 - Mount Hole Location
The correct mounting location for LLS on the tank is the mechanical center of the tank's upper part.
...
Note! The wrong locations for LLS are the edges of the tank's or reservoir's upper part. Wrong LLS location might result in spurious draining and fueling.
In some cases of vehicle's configuration, it’s impossible to get to the mechanical center of the tank's (or reservoir's) upper part. In such cases the tank should be dismounted off the vehicle for the correct (and easy) LLS installation
Step 2 - Drilling Holes in Fuel Tank
The main hole is drilled with Hole Saw 35 mm diameter, using an electric drill.
...
The sensor’s tube should be cut accordingly with the adjusted depth of fuel tank (exact depth of the fuel tank, minus 8 – 10 mm).
Four small holes for LLS fixing screws are drilled with 4.0 mm diameter drill bit
Step 3 - Fuel Depth Measuring and Sensor Cutting
Prior to drilling, take proper measurements of the fuel tank:
Measure the depth of the tank with the help of a measuring rod by plunging the rod into the central hole intended for the sensor.
Along the working length (L) of the product, measure off the length (L1) that is equal to the depth of the tank minus 20 mm
...
Measure the internal height of the tank up to the sensor cover. Cut the sensor based on the measurements and remove 2cm from the bottom of the sensor.
...
Pay attention the middle rod inside the sensor doesn’t touch the tank walls.
After the sensor tube was cut for proper length, the insulation cap should be filled with sealant (silicon compound) for ¼ volume and fit on core rod.
Step 4 - Sealing
Seal the sensor with the insulating cap. The cap should be placed directly above the pipe located in the sensor. Make sure to use sealant resistant to oil and diesel. Fixate sensor to tank. Always cover the sensor with a box to prevent humidity, dirt or dust.

Fuel Sensor Range Calibration
Open the Omnicomm fuel sensor range configurator platform, the following screen will appear
...
...
Submerge the LLS tube completely into the fuel (slowly and carefully). Add the fuel to the measuring tank so as to cover the
...
fuel level sensor along its full L1 length. Wait at least 1 minute until the «The level is stabilized” message appears.
In the program window, click on the “Full” button.
...
Take the
...
fuel level sensor out from the calibration tank and let the fuel drip off from the sensor for 1 minute. In the program window, click on the “Empty” button and click “Save in the sensor”.
Fuel tank calibration involves the process of filling the fuel tank beginning with the empty tank until it becomes full and is characterized by a defined interval for calibration points, with the
...
product readings subsequently recorded into a calibration table.
...
To begin the calibration process, drain the fuel tank and connect the sensor to a PC.
From the Omnicomm configurator platform, open the
...
“Calibration” tab and click “Add Sensor”
...
...
Select the network address and click ok. For one sensor, the
...
“Sensor Network Address” should be set to “1”.
...
In the first row of the “Liters” column, specify the initial fuel volume in the tank.
Define the “Filling step, Liters” according to the volume of the measuring tank, and click “Start calibration”. When adding fuel into the tank, use a measuring tank or a flow-meter with the preset scale interval. Fill out the table as follows:
...
Each of the liter's values for the next steps is inserted in the table according to real fuelling fueling (how many liters of the fuel are in the tank for this exact moment). It can be seen at the fuel counter display or arithmetically adding fuelling fueling step to the former liters value.
...
To finish tank calibration, click “Finish the calibration”. To save the calibration table as an XML-file, click “Export”.

IO Configuration
IO Configuration in the Galooli solution is conducted per unit. To configure the IO’s, perform the following steps:
Manager applications >> My units >> Locate and click on the selected unit >> Configuration tab >> IOs >> Analog >> Click the + to add new IO.
Enter the name of the IO >> Choose “Analog 5” in the Input section >> Check ‘V’ in the “Panorama Display” and “Main Fuel Tank” checkbox.
Click on the Calibrations option to open the calibration table list. Calibration with engine computer requires 2 parameters: Liters when the tank is empty and Liters when the tank is full. Enter bother parameters to calibrate the fuel.
Click “Apply” to finalize the process.
