What are the applications of orifice?
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.
What is an orifice plate used for?
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.
What are the industrial uses of Venturimeter?
Venturimeter is a type of flowmeter that works on the principle of Bernoulli’s Equation. This device is widely used in the water, chemical, pharmaceutical, and oil & gas industries to measure the flow rates of fluids inside a pipe.
What are the uses of orifice meter?
The simplest and most common device for measuring flow rate in a pipe is an orifice meter. An orifice meter is a device with a hole in it, which measures how fast a fluid is flowing, by recording the pressure decrease across the hole.
What is an orifice in engineering?
An orifice is an opening, of any size or shape, in a pipe or at the bottom or side wall of a container (water tank, reservoir, etc.), through which fluid is discharged. If the geometric properties of the orifice and the inherent properties of the fluid are known, the orifice can be used to measure flow rates.
What are the applications of pitot tube?
Pitot tubes are used in anemometers to measure airspeed in wind tunnels and aboard aircraft in flight; they are also used to measure the flow of liquids (see flow meter).
Which type of orifice plate is used for gas application?
Concentric Bore – The most common orifice plate is the square-edged, concentric bored design. It’s used on most processes including clean liquids, gases and steam flow.
Which is the most common material used for orifice plate?
The orifice plate can be made of any material, although stainless steel is the most common. The thickness of the plate used (1/8 – 1/2″) is a function of the line size, the process temperature, the pressure, and the differential pressure.
What is the difference between orifice meter and venturimeter?
The difference between venturi meter and orifice meter are: There are three parts in a venturi meter, and they are the converging section, the throat, and the diverging section. Whereas the orifice meter consists of a thin plate and a bore.
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.
Does orifice plate reduce pressure?
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 are the application of manometer?
Manometer Uses In addition to straight pressure and vacuum measurement, other process variables that are a function of pressure can be readily measured with a manometer. Common applications are flow, filter pressure drop, meter calibrations, leak testing and tank liquid level.
What is the main disadvantage of orifice meter?
Disadvantages of orifice meter: It requires the flow of axial velocity vectors. It causes a pressure drop in the fluid. Its accuracy is affected by the density, pressure and viscosity of the fluid. The range of measurement of viscosity limits of fluids.
What are the three types of orifice plate?
Types of Orifice Plates
- Concentric Orifice Plate (Hole is in the center)
- Eccentric Orifice Plate (Hole is off center)
- Segmental Orifice Plate.
- Others – such as Conical and Quadrant, and Edged Entrance types.
How does orifice reduce pressure?
When a fluid (whether liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice but as the fluid is forced to converge to pass through the hole, the velocity increases and the fluid pressure decreases.
Why orifice is used in pipeline?
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 …
What is the disadvantage of orifice plate?
What is industrial application of manometer?
What is a manometer used for in HVAC?
While the main function of a manometer is to measure system air pressure in heating, ventilation, and air conditioning systems, it can also check airflow, measure positive and negative pressure in ducts, monitor differential pressure across filters and coils, and measure differential pressure for clean room monitoring.
Which is better orifice or Venturi?
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. The turn down ratio of venturi meter is 10:1 while in orifice meter it is 5:1.
