Square-Root Extraction (dP Flow)

dP to flow for orifice meters.

Inputs

Orifice data

Differential pressure in any unit.

Differential at maximum flow.

Flow at full dP, any unit.

Differential below this reads as zero flow.

Verify

Check before relying.

Square root belongs in one place.

  • Extraction in TX or DCS, never both
  • Low-flow cutoff set 5-10%
  • dP range matches the element plate
This calculator is a first-pass screening tool. Verify nameplate data, wiring, module configuration, and calibrator readings before acting.
