What is the use of 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.

What is orifice meter is used to measure?

Orifice meter: is a device used for measuring the rate of flow of a fluid flowing through a pipe.

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.

Can Venturimeter be used vertically?

In principle, the homogeneous model can be used with horizontally and vertically oriented Venturis.

Where are orifice meters used?

The orifice plate flow meter is commonly used in clean liquid, gas, and steam services. It is available for all pipe sizes but it is very cost-effective for measuring flows in larger ones (over 6″ diameter). The orifice plate is also approved by many organizations for custody transfer of liquids and gases.

How does an orifice meter measure flow?

An Orifice Meter is basically a type of flow meter used to measure the rate of flow of Liquid or Gas, especially Steam, using the Differential Pressure Measurement principle. This pressure drop is linear and is in direct proportion to the flow-rate of the liquid or gas.

Why Venturi meter is used in civil engineering projects?

A Venturi meter or Venturi flow meter is a device used to measure the velocity, or flow rate, of fluid flowing through a pipeline. The flow meter is commonly used in plumbing applications to determine the flow of fluids such as water, liquid propane, and oil.

What is Venturimeter describe its construction and working?

A Venturi-meter is a device which is used to measure the rate of flow of a liquid through a pipe. It is an application of Bernoulli’s principle.

Where is orifice plate used?

Orifice plates are most commonly used to measure flow rates in pipes, when the fluid is single-phase (rather than being a mixture of gases and liquids, or of liquids and solids) and well-mixed, the flow is continuous rather than pulsating, the fluid occupies the entire pipe (precluding silt or trapped gas), the flow …

How does orifice plate measure flow rate?

pressure drop
When an orifice plate is placed in a pipe carrying the fluid whose rate of flow is to be measured, the orifice plate causes a pressure drop which varies with the flow rate. This pressure drop is measured using a differential pressure transmitter and can be used to calculate the flow rate.
