Flow measurement devices are used to find the flow of fluids in
a tube. Their requirements change from mass to volume flow. Each type of flow
meter has its application. Fluids, gases, and liquids are determined used
volumetric and mass flow rates.
Flow measuring devices should give accurate measurements.
Different meters have different working principles. Always make sure to choose
a meter that is right for your application. Also, consider some factors like;
· Costs
· Maintenance
· Installation
· And repeatability when choosing a meter.
These meters measure clean water, dirty water, and slurries. Here are the top ten types of flow measurement.
1. Coriolis Meters
Coriolis flowmeters are the most accurate and repeatable sensors in the market today. These meters are perfect for applications where high accuracy levels are needed. Coriolis meters are mostly used in custody transfer applications. It is because they are highly accurate, and their maintenance requirements are low.
2. Differential Pressure
Differential pressure meters are one of the oldest meters. Due to their proven history of performance, they are used today and are highly accurate and popular. These meters are used to measure and control natural gas, custody transfer, and other applications.
3. Magnetic Flow Meters
Magnetic flow meters are one of the most used meters in the market today. These meters are easy to maintain because they lack moving parts. They are also best for measuring corrosive fluids because they will not wear. Magnetic flow meters are also used to measure conductive liquids because they have the best measuring performance.
4. Turbine Meters
Turbine meters are the easiest way to measure the flow of fluids in a pipe. They calculate the flow rates of clean, steam, and gases. Turbine flow meters are also used in custody transfer applications. They are used in petroleum and chemical industries. These meters measure volumetric flow rates and even fluids that have high thickness. Turbine flowmeters are popular due to their high accuracy as well.
5. Ultrasonic Flow Meters
Ultrasonic meters are mostly used in the oil and gas industries. They measure the speed of the liquid in a closed pipe using ultrasonic sound. These meters work by sending a signal to the tube at an angle. The time taken by the call to reach the other side is calculated. These meters measure both liquids, gases, and solids. They also have high accuracy levels and are easy to maintain and install.
6. Vortex Meters
Vortex meters are also referred to as oscillatory flow sensors. They operate by use of a natural fact when a liquid passes through a mock object. The vortex shedding speed is directly related to the energy of the fluid passing through the pipe. Vortex meters are mostly used to measure the flow of the steam.
7. Thermal Flow Meters
Thermal meters are mostly used to measure the flow of gases and liquids. They use a hot sensing object to find the flow of fluids. The sensing element used to measure the flow is usually separated from the flow channel. The steam flow gets heat from the sensing piece, and that heat is directly related to the mass flow rate.
8. Venturi Flow Meters
Venturi meters measure large volumes of liquids with little pressure drops. They are used to measure the flow of fluids in straight pipes. Venturi meters have the best pressure recovery compared to orifice plate meters. Also, their pressure loss is low and used to measure clean, dirty, and thick fluids. Their high pressure and energy recovery makes them fit for small pressure head applications.
9. Orifice Plate
They are commonly used meters. An orifice plate has a hole that is put in the flow. This hole tightens and determines the flow through the construction, giving the flow rate. These meters are popular because they are easy to use and have a simple shape. The orifice meters are used to measure the flow of clean fluids, gases, and steam.
These meters are not fit for several fluids, though. They also measure the liquids in a straight pipe. When the orifice plate is installed in a tube, it produces a pressure difference. This pressure is directly related to the flow rate.
10. Paddlewheel Flow Meters
Paddlewheel sensors are the cheapest flow measuring devices. They come with a paddle, propellers, and rotating disks. These meters have a speed that is directly related to the liquid's energy at one point of the pipe. These meters are highly accurate, and their costs are low. Some designs of paddlewheel sensors are easy to install and maintain, while others are not.
Conclusion
Flow measurement devices are an essential part of the flow. They help you to control the flow of liquids in the industry. Most people need these flow meters, and it is always good to research the best meter. The research will help you select the right meter for your application. Also, make sure to seek advice from the manufacturers.
