What is an orifice plate flow meter?
The orifice plate flow meter is a type of differential pressure flow meter that is commonly used in clean liquid, gas, and stream mass flow measurement.
What is the working principle of orifice meter?
Basic Working Principle of an Orifice Meter The liquid or gas whose flow rate is to be determined is passed through the orifice plate. This creates a pressure drop across the orifice plate which varies with the flow rate, resulting in a differential pressure between the outlet and inlet segments.
What type of flow meter is orifice meter?
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. It is mainly used for robust applications as it is known for its durability and is very economical.
What are the types of orifice plate?
Types of Orifice Plates
- Square Edge (Standard) Bore. For the common square edge concentric bore orifice, the bore and bevel is the standard method of limiting the plate edge thickness.
- Quadrant Edge Bore. The quadrant edge bore is an orifice with the inlet edge rounded.
- Eccentric Bore.
- Segmental Bore.
- General Description.
How many types of orifice plates are there?
There are mainly three types of orifice plates available. Let s take a close look at these three types. Concentric These are most commonly used in pipes below six inches for measuring flow rate of gases, liquids, and steams.
Why orifice plate is used?
An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow (in the latter two cases it is often called a restriction plate ).
What is orifice plate explain its working?
What is advantage 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.
How do you measure an orifice plate?
Divide the flow of the liquid by the velocity of the liquid to determine the area of the orifice in square feet. In the above example, you would divide 8 by 2. The total area of the orifice would be 4 square feet.
What are the advantages and limitations of orifice plate?
How does a orifice plate work?
Orifice plates are a primary flow element, detecting the flow of a fluid passing through the plate by sensing the pressure drop across the plate. When a fluid flows through a restriction in a pipe, it creates a pressure difference between upstream and downstream of the restriction.
Which is the main advantage of orifice meter?
Advantages of Orifice meter: The Orifice is small plates and easy to install/remove. Offer very little pressure drop from which 60% to 65% is recovered. The orifice meter can be easily maintained. Measures a wide range of flows.
What are different types of orifice plates?
Several types of Orifice Plates
- Square Edge (Standard) Bore. For the common square edge concentric bore orifice, the bore and bevel is the standard method of limiting the plate edge thickness.
- Quadrant Edge Bore.
- Eccentric Bore.
- Segmental Bore.
