BPT ROX™
Orifice and Venturi Flow Meters. ROX™ is a unit operation for orifice and venturi flow meters (ISO 5167) and restriction orifice modelling.

What is ROX™
ROX™ is a process simulator unit operation for Orifice and Venturi Flow Meters and Restriction Orifice Modelling.
ROX™ for can be used in both Steady State and Dynamic Simulations.


Since Orifice and Venturi Flow Meters are not commonly available as standard unit operations in process simulators, if a model or either unit is required, the user currently has to estimate or approximate the operation of this equipment.
This software comes as an extension for Petro-SIM from KBC Advanced Technologies and Aspen HYSYS from AspenTech.
