A Venturi flow meter is a differential pressure flowmeter.

. Flexible drive-train sealed ball bearings requires no external power or batteries. This video explains how Venturi tubes orifice plates and flow nozzles work as flow meters. This pressure difference in between inlet and throat is determined by the help od U-tube manometers this.

The venturi meter is placed in a pipe carrying the fluid. Working -Venturimeter works on the principle of Bernoullis equation ie when velocity increases pressure decreases. It is invented by American Engineer Clemans Herchel and named by the Italian physicist Giovanni Venturi.

Differential pressure flow gauges cause a narrowing in the pipe that creates a decrease in pressure across the flow gauge. Working principle of Venturimeter. It works on the basic principle of Bernoullis Equation.

To measure the flow rate that is discharged a pressure drop occurs between the entrance and throat of the venturi meter. Any point of flowing fluid in the venturi meter there will be pressure energy potential energy and kinetic energy. The differential flow meter is the most common device for measu.

The pressure difference is created by reducing the diameter of the pipe causing the fluid to flow faster. Venturi flow meters are often used to measure the flow of fluids such as air natural gas coal gas and water. Ad Designed to operate in real-world environments turbulent flows suspended solids and more.

Since the cross -section decreases from inlet pipe to throat the velocity of the fluid increases and hence the pressure decreases. It is often used to measure the flow of pressure pipes. A venturi works by measuring the difference in pressure at two different locations.

When the fluid used to pass through the venturi meter there is no difference in inlet but at the throat the velocity is used to increased and there is a decrease in pressure this is due to decreasing cross-sectional area from inlet to throat. Working equation for venturi meter. Working Principle of Differential Pressure Flow Meter Previously it has been mentioned that this DP Flow Meter uses bernoulli law to measure fluid flow in pipes.

G Cd ρC Where Cd coefficient of discharge ρ density of the fluid and C is constant for a meter and is equal to 2 2 2 1 21 AA AA By applying Bernoullis theorem at the inlet and throat sections the. Cross section of throat is less than cross section of inlet pipe. The Venturi flow meter is a combination of a Venturi tube a differential pressure transmitter and a valve block.

The theory states that when the cross-sectional area of the flow decreases a pressure difference is created between the different regions of the flow. Venturi Meter is a device in which pressure energy is converted into kinetic energy and it is used for measuring the rate of flow of liquid through pipes. Venturi meter works on the principle of the Bernoulli equation such that the velocity of the fluid increases as the pressure decreases.

In the venturi meter the fluid flow rate is reduced due to the reduction of the cross-sectional area. Our Electromagnetic Flow Meter Accurately Measures The Flow Of Water Conductive Liquids. Venturi Meter Working Principle.
