Venturi tube flow meter - Flow measurement with primary element

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

  • Complies with ISO 5167-4 datasheet
  • Precise differential pressure flow measurement
  • Economical
  • No measuring tube wear
  • High repeatability and reliability
  • Low pressure drop

Features

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.
