Loss or record
Level dropped but dispensed litres do not add up — check measurement before assuming theft.
Real loss needs evidence beyond one gauge reading.
Triangle close
Opening tank balance plus receipts minus dispense minus closing should near zero for the same period.
Close per shift if daily is too noisy.
Rule out error
Compare dip and level probe same time. Track meter calibration dates.
Seasonal temperature swing needs a baseline.
- Shift open/close reads.
- No dispense without machine ID.
- Transfers as separate lines.
- Define litre and percent thresholds.
Deviation
Litres per hour vs fleet average flags operational causes before loss.
Telemetry is a second filter, not sole proof.
Investigation order
Records first, physical leak second, authorisation third.
fuel management module lists dispense and machine use in one period.
Reporting
Show unexplained gap in litres and cost separately.
fuel automation keeps device-origin dispense records immutable for disputes.
Prevention
Make shift close habit, not post-incident analysis.
Threshold alerts require a written reason to close.
