Dipgauge: Oil Tank Gauge

Compare a delivery invoice with before-and-after tank depths, entered consumption and a user-chosen reading tolerance. Save the tank chart and inputs together for later review. HOW IT WORKS 1. Open Check, create a delivery check, and select the chart matching your installed tank and orientation. 2. Enter before and after depths in inches, invoice and between-dip consumption in US gallons, and a reading tolerance. 3. Review the modeled interval and full calculation, save the check, and share its report if useful. The gauge, configured tanks, burn-rate planning, delivery log and reference guides remain available. Find Learn in Plan. WHAT TO KNOW This is a paperwork review aid, not leak detection, proof of shortage, a safe-fill instruction or regulatory compliance. The interval varies depth readings independently; it is not statistical confidence. Tank fit, tilt, temperature, settling and uncertainty in consumption are excluded. Non-propane published charts only; up to 30 saved checks. iPhone and iPad.
