What are the advantage and disadvantage of Venturi meter and orifice meter?

Advantages of venturi meter: Its behaviour can be predicted perfectly. It can be installed vertically, horizontally, inclined. They are more precise and can be used for a wide range of flows. About 90\% of the pressure drop can be recovered.

What are the advantages Venturi over orifice?

Advantages of Venturi mater over Orifice meter : Venturi meter is used for operating in-compressible fluids. Venturi meter can handle large range of flow rates of fluid than that of orifice meter. Turn down ratio is 10 : 1. Co-efficient of discharge is relatively high 0.98.

What are the advantages and disadvantages of orifice plate?

Advantages and disadvantages of orifice plate Simple in construction, the standards for construction and calibration are readily available. They are cheap; their price does not increase dramatically with size. Easy to install and remove. They are efficient and reliable for many years.

Why are Venturi and orifice meters used?

Venturi Meter versus Orifice Meter:- Venturi meters and Orifice meters are devices which are used to measure average velocity, volumetric flow rate or mass flow rate of a flowing fluid by reducing the pressure of the flowing fluid.

What are the Advantage uses of Venturi flume?

Venturi flumes have two advantages over weirs where the critical depth is created by a vertical constriction. First, the hydraulic head loss is smaller in flumes than in weirs. Second, there is no dead zone in flumes where sediment and debris can accumulate; such a dead zone exists upstream of weirs.

What is the difference between venturi meter and orifice meter?

The difference between venturi meter and orifice meter are: The pressure loss in venturi meter is 10\% while in the orifice meter the pressure loss is 50-60\%. The coefficient of discharge in the venturi meter is 0.98 while in orifice meter it is 0.6.

Why is venturi meter more accurate than orifice meter?

Lower flow rate reduces the accuracy of orifice plates. Higher flow rates in high quality orifice plates gives increased accuracy. Venturimeters are widely used for high flow rates. They can handle 25-50\% more flow rate than an orifice.

What is difference between Venturimeter and orifice meter?

Venturi meter and orifice meter are used for measuring the volumetric flow rate of the fluid that based on the continuity equation and Bernoulli’s equation. The difference between venturi meter and orifice meter are: The pressure loss in venturi meter is 10\% while in the orifice meter the pressure loss is 50-60\%.

What are Venturi meters used for?

Venturi meters are flow measurement instruments which use a converging section of pipe to give an increase in the flow velocity and a corresponding pressure drop from which the flowrate can be deduced. They have been in common use for many years, especially in the water supply industry.

What is difference between orifice meter and Venturi meter?

What are the advantages of Parshall flume over Venturi flume for flow measurement in open channel?

The principal advantages of Parshall flume include low head loss, self-cleaning capability and their ability to withstand relatively high degrees of submergence without affecting the rate of flow.
