Flow measurement
Fields of application
This method is widely used in hydraulic processes and aerodynamics to measure fluid velocity in piping.
Industrial sectors that use venturi tube flow measurement are the metallurgy, chemical and oil industries. These sectors need to measure and control the flow of liquids and gases (air, nitrogen, etc.).
Benefits
The venturi tube is a method of measuring fluid flow using a cylindrical depressurizer with a constriction.
As a fluid flows through the tube, its flow rate increases due to the restriction. The pressure difference between upstream and downstream is proportional to the flow rate.
