Pipe, meter and purge volume estimator

Build the IGEM/UP/1 Table 3 and Table 4 volumes directly in the browser. Add every pipe segment that forms part of the test, select the installed diaphragm or rotary meters, and include any purge hose to replicate the worksheet logic. Pipe purge volumes use the same multiplier defined in IGEM/UP/1 Sheet 1.

Pipe size (DN)	Length (m)	Volume per metre (m³)	Installation volume (m³)	Purge volume (m³)	Actions

Diaphragm meter (Table 3)

Rotary meter (Table 3)

Purge hose size (Table 4)

Pipe purge multiplier

Add at least one pipe segment to calculate installation and purge volumes.

Cross-check these totals with the latest IGEM/UP/1 publication on the IGEM technical services site and guidance in Section 8 to confirm that the chosen approach still reflects the published standard before issuing the procedure.

Detailed Procedure

Reminder: Document instrument calibration dates and verify leak detection fluid compatibility with pipe materials.

Calculation Support

Use these assisted calculations to document the rationale for your chosen test pressures and hold times. Values are stored with the rest of the template so that the full decision trail is available for audit.
