Tank Monitoring
Distinguishing Tank Leakage from Consumption
A falling level is evidence of change, not automatic proof of a leak.
A falling level is evidence of change, not automatic proof of a leak. Interpret it with inflow, normal demand and measurement uncertainty.
Establish the operating baseline
Record expected consumption schedules, deliveries and transfers. Convert level to volume correctly before calculating rates. Identify periods where normal draw-off should be absent, and note temperature or density effects relevant to the measurement method.
Use corroborating evidence
Compare level trends with flow meters, pump states or valve activity where available. Require a sustained and meaningful change above the noise floor. A faulty sensor, delayed batch upload or unrecorded transfer can otherwise trigger a misleading leak notification.
Treat alerts as investigation triggers
Define who checks the condition and what records they review. Label uncertain detection appropriately and retain the supporting trend. Validate thresholds using normal operation and controlled tests suitable for the site rather than claiming guaranteed leak detection from level data alone.
FAQ
Can tank level identify the leak location?
Usually not by itself. Additional inspection or instrumentation is needed to locate and confirm the cause.
