What is the use of venturi Metre?
A venturi meter is also called a venturi flowmeter. It is used to calculate the velocity of fluids in running through a pipeline. The fluid may be a liquid or a gas. The meter consists of a pipe with a narrowing throat that expands back to it’s original diameter on the other side of the choke point.
How Venturi meter are used for flow measuring?
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.
Where do we use orifice meter?
Applications of Orifice Meter It is used to measure the flow rate of fluids in their single state (i.e. gaseous state or liquid state). It can also be used to measure the flow rate of fluids in a mixed state (both gaseous and liquid states) such as, wet steam, or natural gas with water.
Why do we measure fluid flow?
Measurement of flow, whether it is a liquid or gas, is commonly a critical parameter in many processes. In most operations it is important to know that the right fluid is at the right place at the right time. Measuring flow and pressure can provide this security to the process and personnel.
Which meter gives direct reading of flow of fluids?
Coriolis flow meter is an optimal instrument to measure the mass flow rate of liquids, gases and even two-phase flow.
How is Venturi meter considered an important device to the maritime field?
Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.
How does a Venturi meter measure flow?
A Venturi meter is used to measure the flow rate through a tube. It is based on the use of the Venturi effect, the reduction of fluid pressure that results when a fluid runs through a constricted section of pipe. – as a result the two meters indicate the difference in pressure by means of a height difference h.
Which is more accurate Venturi meter and Orificemeter?
For measuring mass flow rate of liquid flowing inside tube, venturimeter is the most accurate device. Since experimental measurement by venturimeter is 0.96-0.99 times theoretical measurement. Next comes, orifice meter which is 0.6- 0.62 times theoretical measurement.
