Industrial Venturimeter: Working Principle, Benefits and Applications
by A.S. Engineers & Fabricators, Ambernath MIDC, Maharashtra. Technical Team | 38+ Years | Accurate flow measurement is essential for efficiency, safety, and process control in today’s industries. Reliable flow measurement enables industries to optimise production and reduce operating costs, whether it be water in treatment plants, steam in power stations, or hydrocarbons in refineries.
A venturi meter is one of the most trusted flow-measuring devices by differential pressure used in many industries throughout the world. The Venturimeter is highly accurate, has low pressure loss, and has a long service life. It is used extensively in water treatment, oil & gas, petrochemical, power generation, chemical processing, and manufacturing facilities.
About us: ASEFS India is a well-established manufacturing company situated in Ambernath MIDC, Maharashtra, India. We manufacture a wide range of precision-engineered industrial venturimeters and Venturi flow meters for demanding industrial applications. With over 38 years of manufacturing experience, ASEFS India supplies tailor-made flow measurement equipment to customers in India, the Middle East, Africa, and other parts of the world.
What is an INDUSTRIAL VENTURIMETER?
An industrial venturimeter is a flow-measuring device that is used for measuring the flow rate of liquids, gases, and steam flowing through a closed pipeline.
Unlike mechanical flow meters, a Venturimeter has no moving parts. It determines flow by creating a pressure differential as the fluid passes through a specially designed constricted section known as the throat.
Engineers can then use the pressure difference to accurately calculate the fluid flow rate.
Industrial venturimeters are popular for the following reasons:
- High Accuracy
- Excellent Repeatability
- Low Permanent Pressure Loss
- Long Service Life
- Minimal Maintenance
- Reliable Performance
Working Principle of an Industrial Venturimeter
The Industrial Venturimeter operates on Bernoulli’s principle, which states that as the velocity of a fluid in motion increases, its pressure decreases. The Venturimeter is composed of three parts.
1. Section Converging
The fluid flows through the converging part of the venturimeter.
As the diameter of the pipe gradually reduces:
- Flow velocity increases.
- The pressure starts to fall.
This smooth transition cuts down on the turbulence.
2. Part of the throat
The narrowest part of the venturi meter is the throat.
At this stage:
- Fluid hits maximum velocity
- The static pressure is at its minimum
The pressure difference is measured at the inlet and throat using pressure transmitters or differential pressure instruments.
3. Expansion Section
The fluid then passes through the throat and into the diverging section.
Here:
- Decrease in flow velocity
- Pressure is slowly returning
The carefully designed diffuser angle also guarantees that the permanent pressure loss is very low compared with many other flow measurement devices.
Components of an Industrial Venturimeter
The Venturimeter has the following parts.
- Inlet Section
- Converging Cone
- Throat
- Diverging Cone
- Pressure Tapping Points
- Differential Pressure Transmitter
- Connecting Flanges
The finished assembly gives accurate and reliable flow measurement even in demanding industrial environments.
Benefits of Using an Industrial Venturimeter
Advantages of the industrial venturimeter are the following.
High accuracy of measurement
Venturimeters provide very precise flow measurements under a broad range of operating conditions.
Low-pressure drops
Venturimeters recover most of the pressure after the throat, thus reducing energy losses, unlike orifice plates.
No Parts in Motion
There are no rotating or mechanical parts, so maintenance requirements are very low.
Long service life.
Industrial venturimeters are designed for continuous duty and will give reliable service for decades.
Suitable For Large Pipes
Venturimeters are very suitable for accurate flow measurement in medium- and large-diameter pipelines.
High Reliability
Their simple design ensures a reliable operation even in harsh industrial conditions.
