When it comes to discussing a topic about flow measurement in industries, the name flow meters sounds loud. Measurement refers to calculating the flow rate of liquids in terms of volume, pressure, and speed. It is necessary to keep the industrial working system efficient, and it is an important part of fluid processing that cannot be denied. The primary goal to measure and regulate the flow of liquids is linked to many core values. Ensuring product quality, the safety of workers, and asset management are the main objectives of the fluid dimension.
What is the need for measuring fluid flow?
The need for measuring the flow rate is distinct in various industries. So, to produce accurate results, there are different types of flow sensors available. They work seamlessly to check the fluid flowing inside the piping system, and they enable the technicians to control the fluid flow to keep the production appropriate. There are many types of flow devices available, but the commonly used by various industries are as follows.
Disparity pressure flow sensors
These are the best devices that are widely used for flow measurement applications. The industries like oil, gas, and refineries mainly depend on these meters. These measuring tools have primary and secondary components to measure the flow rate. The primary element aims to work for obstructing the fluid inside the pipes. When the obstruction in the flow occurs, it creates pressure in the pipe. The secondary component works to measure this pressure gap, thus obtaining results for the flow rate. This device comes with an electronic meter that displays the measured results. Many varieties of this meter are available, such as flow tubes, venturi tubes, orifices, variable-area meters, and flow nozzles.
Positive displacement flow extent
This type of micro-tech flow meter works seamlessly to measure the flow rate for viscous liquids. Viscous liquids are liquids that do not flow easily and are thick. They move sluggishly in the pipes usually, and an example of such liquids is oil and syrups. When the flow of such liquids passes through positive displacement, it measures their rate. The liquids such as petrochemicals, paints, and adhesives are the ideal fluids for such devices. The application of these meters is widely used in industries that are engaged in:
Food processing
Pharmaceuticals
Power production
And chemicals
These devices are beneficial in terms of providing higher accuracy, low operating cost, self-operation, etc. There are several types of this flow meters available for industrial use, and you can take the example of piston meters, rotary vane meters, nutating disks, and oval gears, etc.
Velocity flow measuring meters
Velocity refers to the speed of a thing moving towards the direction of motion. As the name suggests, these meters measure the flow rate of liquids based on speed. Their large implementation is available for the industries that are related to:
Water waste treatment
Power generation
Refinery and chemical
These are the flow meters that can be connected directly to the pipelines. They measure the flow rate by sensing the velocity of the fluid flowing inside the pipes. They come with easy fittings to use directly on the pipes. These meters are popularly known for their major advantages, such as:
Higher accuracy for flow rate measurement
Reliable operation
Low maintenance
And the ability to work in varying temperatures and pressures.
These flow measuring devices are available in several types. You can say that vortex meters, ultrasonic, electromagnetic, paddle wheel, and turbine are the perfect velocity meters.
Mass flow measuring tools
Professionals use these meters when there is a need to measure the flow rate of fluids flowing in mass. They are ideal solutions to attain results for mass rate measurement. These meters do not work like differential pressure meters to measure the volumetric flow. But, they are used significantly to measure liquids; those velocities vary with speed. The major use of these meters is in the industries like chemical and food processing units. These industries require highly precise results for flow rate measurement and stability. Some of the advantages of these meters are:
Outstanding measuring outputs
Finest operation with temperature varying
Longer span
The major types of these flow computing devices are Coriolis and thermal mass flow rate meters.
Open channel meters
The flow meter is used as a primary source of flow measuring in an open channel. The primary application of these meters is in tunnels, canals, rivers, and streams, etc. The primary use of these meters is in the water and wastewater industries, and they work to measure the flow rate of water and deliver precise results. The major advantages of these meters are easy to install design, greater accuracy, and modular system.
These are the five major types of modern-day flow sensing and measuring devices. They have different abilities to measure the rate of fluids. But, the objective for all these tools is the same. Flow sensors or controllers or meters, whatever you want to refer them, are useful measuring devices. They perfectly design and developed by professional manufacturers to detect flow rates. These devices are classified as per the elements they measure. They ideally work to calculate the flow rate for the gases, liquids, and solids as well. Major industries like petrochemicals, power, chemical, food, beverages, paint manufacturing, etc., use them.
Some of the operations for flow measurement are accurately working that do not need to be fixed. The different flow measuring devices work seamlessly to evaluate liquids’ flow rate to contribute significantly to production processes. However, most industries have now switched the use of flow measurement from mechanical to digital meters. It enables the manufacturers to get easy access to the measurement of flow rates without any trouble. However, digital technology is proving time and money-saving due to fast and convenient operation.
The Final Words
A good measurement practice is what makes the production process stand apart. But, the choice of flow meters could vary in different industrial environments. So, it is necessary to choose them wisely as per the needs and also from the certified manufacturers.
