Leakage survey worksheet
Pneumatics Practice Notes
Blank on purpose. Copy a flow figure only from a measurement you made, or from the Compressed Air Tip Sheet #3 cell that matches an orifice you estimated. Do not invent a share of air saved.

The method on the site page is from U.S. Department of Energy Compressed Air Tip Sheet #3, Minimize Compressed Air Leaks, revised August 2004, and from the ultrasound description in Compressed Air Best Practices, 3 November 2025. This file is not a test by this site.

Columns:
Tag | Place | Supply pressure | Method (ultrasonic or soap) | Intentional vent? (yes/no) | Estimated orifice, if any | Flow, if measured or taken from the matching tip-sheet cell | Repaired (date) | Checked again (date) | Notes

Places the tip sheet names: couplings, hoses, tubes, fittings, pipe joints, quick disconnects, FRL (filter, regulator, lubricator), condensate traps, valves, flanges, packings, thread sealants, point-of-use devices.

Two cells from that tip sheet, for reference only: at 90 psig a 1/16 inch orifice is listed as 5.72 cfm; at 100 psig a 1/4 inch orifice is listed as 100.9 cfm. Multiply by 0.97 for a well-rounded orifice and by 0.61 for a sharp one. Leave flow blank when you have not estimated an orifice.
