Your Gauge Sheet Sits on a Clipboard While Production Runs Two Weeks Behind

Paper gauges get re-keyed into someone else's spreadsheet days later, and the barrels you actually moved come back wrong. Gauge the tank, enter the numbers, and walk away with net standard barrels you can defend.

Why Tank Gauge Calc

The custody-transfer maths,
done at the battery

๐Ÿ“

Your Strapping Chart, Built In

Set each tank up once โ€” a barrels-per-inch factor or your full strapping table pasted in. Feet, inches and quarters go in; barrels come out, interpolated between rows the way the chart intends.

๐ŸŒก๏ธ

Corrected to 60°F, Properly

Observed temperature and API gravity drive a real API MPMS Ch.11.1 volume correction factor โ€” not a rule of thumb. BS&W comes off the corrected volume, and every step is shown with its formula.

๐Ÿ“ด

Works With No Signal

Lease roads don't have bars. Installs to your phone as an app and runs fully offline. High-contrast light mode reads in direct sun; dark mode for night gauges. Nothing leaves the phone.

Field-ready. Built for the tank battery.
