Orifice Flow
Calculation Tool

Our software assists engineers and technicians in accurately calculating orifice flow rates and related measurements based on the ISO 5167:2003 standard. Designed for precision and efficiency across industrial applications.

• Calculate the orifice diameter for a given maximum flow rate and differential pressure.
• Determine the differential pressure for a known orifice diameter and specified flow rate.
• Compute the actual flow rate based on a given orifice diameter and pressure drop.

Designed for flange-type, D and D/2 impulse pressure tappings. Supported pipe diameters from 50 mm to 1000 mm, or Reynolds number > 5000.
