Differences between entered cumulative readings only. A high value is a review flag, not proof of a leak. Check units, meter resets and estimated readings.

How to use Water Meter Reading Auditor

Explore the worked example. Use dated cumulative readings to compare daily usage between intervals and flag an entered usage threshold.
Replace the meter readings with your own entries. Set review above · m³/day.
Choose “Analyze the readings”. Review meter intervals, then compare the visual overview with the detailed tables.
Capture alternative scenarios, download a reusable project and export the selected table or a report when you are ready.

A starting point

Use dated cumulative readings to compare daily usage between intervals and flag an entered usage threshold. The example is illustrative and can be replaced.

Know what you are comparing

Does a flagged interval prove there is a leak?

No. A flag only compares the entered interval usage with your threshold. Meter rollovers, incorrect entries and legitimate changes in consumption need separate investigation.

Files, privacy & saving

Calculations run locally in a browser worker. Input CSV files use the column names in the downloadable template and keep your current settings. Projects restore inputs and up to four scenarios. Imports are limited to 1 MiB and 100 entries. There is no automatic saving. Public pages include advertising and optional analytics; see our privacy policy.

CSV exports contain the entire selected table. JSON and printable HTML reports include all result tables; open the report and use your browser’s Print command for PDF.
