OrificeQ Pro

OrificeQ Pro is a professional engineering tool for natural-gas flow measurement through orifice plates. It implements the industry standards — AGA Report No. 3 (2013), AGA Report No. 8 (2017) and ISO 5167-2 — so your results are accurate, traceable and audit-ready. CALCULATE WHAT YOU NEED • Flow rate (Q), differential pressure (ΔP) or orifice diameter (d) — solve for any of the three. • Plate sizing: find the orifice diameter for a target flow. • Z-factor (compressibility) via AGA-8 DETAIL and GROSS — simple gravity or full gas chromatography (GPA 2261). ENGINEERING DEPTH • Reader–Harris/Gallagher discharge coefficient, expansion factor, Reynolds number, beta ratio and more — all shown. • Built-in conformity check: every result is validated against AGA-3 valid ranges, so you know instantly if it is in spec. • Live unit converter (pressure, temperature, flow, length). PROFESSIONAL REPORTS • Generate a complete AGA-3 verification report as a PDF — ready for clients and audits. • Export to Excel (.xlsx) for further analysis. • Add your company logo and a professional signature to your reports. • Calculation history, synced to your account. ONE-TIME PURCHASE OrificeQ Pro Premium unlocks Excel export, custom branding, the full report suite and unlimited history — a single payment, no subscription, and it works offline. BUILT FOR PROFESSIONALS Designed for measurement engineers, field technicians, metering specialists and consultants in the oil & gas industry.
