DROP TUBE CUT MATH
Enter the measurements and get the cut length that puts the overfill valve at the 95 percent regulatory fill level. Supports Franklin Defender, EMCO, and OPW ISO valves, with the seat to bottom, tank height and riser measurements each handled properly. Upper cut, lower cut and total length come back with the shutoff height so you can check the result before you cut anything.
TANK CHART BUILDER
Build a volume chart in eighth inch increments for any tank, and export it as a PDF you can leave on site or file. Built in instructions walk through fitting the chart to a real tank, including why the 95 and 90 percent overfill heights follow the tank diameter alone and hold steady when the length changes.
ERROR CODES
Nearly 600 codes covering Gilbarco Encore 300, 500S and 700S, Wayne Ovation, Veeder-Root TLS-300, TLS-350, TLS-450, TLS-450 PLUS and TLS4, and Franklin INCON EVO 550 and 5000.
Tap any code and you get what it actually means, then an ordered list of what to check, most likely cause first, so you can work the alarm instead of just reading it back. Line test failures start with the programming that causes most false failures. Console faults tell you when the alarm is an audit entry rather than a fault. Where an alarm carries a compliance consequence, that is stated after the repair steps, not instead of them.
Searchable, fully offline, and written to be verified against the manufacturer service manual rather than to replace it.
PUMP CONTROLLERS
Fault codes, status codes, DIP switch settings and calibration notes for FE Petro MagVFC and Guardian SPGC 220 controllers.
EPD THREE YEAR INSPECTION
Work the inspection criterion by criterion and get a clear pass or fail, then export a signed PDF record. The footer reminds you to keep the record copy for three years, because that is the part people forget.
MEASUREMENT HISTORY
Every calculation is saved with its site name, so last year's job is there when you go back. Re export any past calculation as a PDF.
BUILT FOR THE FIELD
Everything ships inside the app. No account, no login, no server, no advertising, and nothing collected about you or your sites. It works in a tank pit with no bars.
Available in English, Spanish, French, German, Hindi and Chinese.
