Frequently Asked Questions
Quick answers to common questions.
What fluids are supported?
The calculator supports liquid and gas dP flow measurements, with fluid-specific inputs, scenario checks and review flags.
Is the calculation methodology approved?
This calculation method is based on ISO 5167 gas/liquid orifice sizing methodology and its calculation outputs are subject to normal engineering review and project document control procedures.
Can I generate a PDF report?
Active subscribers can download individual or combined PDF reports, including input conditions, grouped results and engineering checks.

Engineering Disclaimer
The calculator implements ISO 5167-based liquid and gas orifice sizing methods. Results must be reviewed by a qualified engineer for the actual operating conditions, installation geometry, methodology limits and applicable design requirements. Preliminary plate-thickness screening is not a final structural or buckling certification. Results are not OEM-provided validated sizing results.
