Orifice Plate Flow Test
Upstream - Downstream = Differential → Flow
Orifice Plate Configuration
—
0.62 sharp-edged • 0.75 rounded • 0.95 nozzle
💡 The Calculation
Differential = Upstream - Downstream
Flow = Cd × A × √(2 × ΔP / ρ)
Flow = Cd × A × √(2 × ΔP / ρ)
Test Points
Enter upstream and downstream gauge readings. Differential and Flow are calculated automatically.
