A venturi meter is a device used to measure the flow rate of a fluid in a pipe. It consists of a converging section followed by a throat and then a diverging section. As the fluid flows through the venturi meter, the velocity increases in the converging section, causing a decrease in pressure. The pressure difference between the converging and diverging sections is used to calculate the flow rate of the fluid. Venturi meters are commonly used in industries such as water treatment, oil and gas, and chemical processing to monitor and control the flow of fluids.

Venturimeter
A Venturimeter is a device used in fluid dynamics to measure the flow rate of a fluid flowing through a pipe. It consists of a converging section, a throat section, and a diverging section. The converging section reduces the cross-sectional area of the pipe, causing the velocity of the fluid to increase. This increase in velocity is accompanied by a decrease in pressure, as per Bernoulli's principle. The throat section has a constant cross-sectional area, and the velocity of the fluid remains high. The diverging section increases the cross-sectional area of the pipe, causing the velocity of the fluid to decrease. This decrease in velocity is accompanied by an increase in pressure, also according to Bernoulli's principle.
Principle of Operation
The Venturimeter operates on the principle of conservation of mass and Bernoulli's principle. As the fluid flows through the Venturimeter, the following equations hold:
- Conservation of Mass: The mass flow rate (ρAv) is constant throughout the pipe.
- Bernoulli's Principle: The total energy of the fluid (pressure + kinetic energy) remains constant.
Measurement of Flow Rate
The flow rate through the Venturimeter can be determined by measuring the pressure difference between the throat section and the upstream section. This pressure difference is proportional to the square of the velocity of the fluid in the throat section, which is in turn related to the flow rate.
Advantages of Venturimeter
- High accuracy in flow rate measurements
- Low pressure loss compared to other flow measurement devices
- Suitable for a wide range of fluids
- Can be used for both liquids and gases
- Relatively easy to install and maintain
Disadvantages of Venturimeter
- Requires straight pipe sections upstream and downstream
- Can be expensive to manufacture
- May be affected by viscosity and density changes in the fluid
