The fuel reading is stuck
Several platforms can be used to identify the problem: | In order to confirm that the fuel reading is indeed stuck, follow these steps: Find a day when the generator was certainly in use. Generate a detailed report on that day using the Pro application, containing two fields: "Generator X Total used" and "Generator_X.Engine_Hours". In the event that the working hours of the generator change and the fuel consumption does not change accordingly, then the reading is indeed stuck and you should proceed to the next step.
Using one of the Galooli platforms, create a detailed report and determine when the fuel reading last changed . If you have determined the time and date at which the readings of the fuel stopped, proceed to the next step.
Check whether the fuel calibration table has been modified in accordance with the previous section and make sure that a calibration table has been applied properly.
Check via the Power Center if the sensor's open-air value exceeds the OA value of +7 or -7, it may indicate a fault.
Verify that the fuel sensor pores are not blocked at the diaphragm.
Make sure that there is no sludge in the fuel tank.
Make sure the fuel is of good quality.
Make sure that the fuel sensor is properly secured to the sensor securing rod.
Check for signs of wear and tear.
Recalibrate the sensor.

The fuel readings indicate a wave pattern
Use the detailed report provided by the Pro application to identify the issue. | Create a detailed report using Galooli Pro application in order to determine when the fuel readings begin to behave in a wave pattern. Proceed to the next step if you have determined the time and date.
Check whether the fuel calibration table has been modified in accordance with the previous section and make sure that a calibration table has been applied properly.
Check via the Power Center if the sensor's open-air value exceeds the OA value of +7 or -7, it may indicate a fault.
Verify that the fuel sensor pores are not blocked at the diaphragm.
Make sure that there is no sludge in the fuel tank.
Make sure the fuel is of good quality.
Make sure that the fuel sensor is properly secured to the sensor securing rod.
Check for signs of wear and tear.
Recalibrate the sensor.

The fuel readings contain “noise”An example of noise would be a deviation from how the Galooli system interprets the fuel trend from a particular site.
The following factors may be contributing to this noise, either individually or in combination: The presence of sludge in the tank A large amount of water has been mixed with the fuel in the tank. Fuel sensor malfunction An improperly installed fuel sensor in which the rod of the sensor is not firmly fastened to prevent vibration.
 | First you need to identify the noise readings: Step 1: Build a summary report with the following fields:
•unit id
•Refuels
•Numeric Calculated field"(IF(('Refuels'>8)||('Drops'>8);1;0).
The assumption is that a normal norml functioning sensor should not experience refuel or drop count of more than 8 in a day.
The count can vary depending on the client and their mode of operation.
Step 2: Under data Aggregation use "Daily"
Step 3: Run the report and under Calculated field (Named "1 equals irregular fuel")
Step 4: Filter out 1, this represents the sensors with irregular fuel/noise. How to resolve noise issues? Resolution approach depends on the cause of the noise. To know the exact cause of the noise, a site visit for physical inspection is recommended. Below, a list of action for different root cause is highlighted. Presence of sludge in the tank Evacuate sludge from the tank. Clean the fuel sensor by removing sludge deposits from the diaphragm. Wash the sensor with fuel but be careful to ensure fuel does not penetrate the cable or internal circuitry of the sensor. Power up the sensor and observe for normal functionality. If sensor reading is OK, then sensor can be re-used otherwise a replacement is advised. Re-install the sensor and calibrate as per standard operating procedure.
Presence of water in the tank
Evacuate fuel contaminated with water from the tank. Inspect the sensor to be sure there is no water ingress in the cable or sensor internal circuitry. Wash the sensor with fuel but be careful to ensure fuel does not penetrate the cable or internal circuitry of the sensor. Power up the sensor and observe for normal functionality. If sensor reading is OK, then sensor can be re-used otherwise a replacement is advised. Re-install the sensor and calibrate as per standard operating procedure. Identify potential points of water ingress to the tank and seal it off.
Faulty fuel sensor Once confirmed faulty, replacement is recommended. Installation issue (Lack of rigidity)
When identified as the cause of the noise, re-install the sensor, and make sure the sensor rod is securely fastened to the tank to prevent excess vibration when generator is running. |
