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.

Connection	Welded (BW) or flanged
Material	Standard: Carbon steel, stainless steel Others: Depending on application
Fluid	Liquid, gas, steam
Pipe	From Ø 50 to 1,200 mm (depending on model)
Accuracy	0.7% to 1.5% of max flow (depending on model)
Measurement repeatability	0,10 %
