A flow sensor, also known as a flow meter, is a device that uses electrical or mechanical subsystems to measure the flow rate of fluids or other substances, calculate and record the measurement reading. The type of the fluids determines the flow meter be applied.
Knowing the perfect flow sensor for accurate measurements may be pretty tricky since the type of application determines the best flow sensor that suits it. Will learn how to know the best flow sensor for the accurate measurement in a specific application Considering several factors.
How to know the perfect flow sensors for accurate measurement.
When you want to know which flow sensor can be the best for your application, you need to put the following into consideration.
1.The type of fluid
You should know the type of fluid the flow sensor is to measure since not all flow sensors can measure the flow rate of all liquids to obtain accurate results. For example, magnetic flow meters do not provide accurate results on gases and oil measurement.
When you use a magnetic flow sensor to measure the flow rate of magnetic materials, you are likely to obtain less accurate results since the magnetic material interacts with the force in the fluid’s magnetic flow meter.
2. The moving parts of the flow sensor
Moving parts in a flow sensor may make the flow sensor wear and tear after some time which may interfere with the efficiency of the flow sensor, thus leading to less accurate results and the failure of the flow sensor to operate.
The moving parts also require frequent maintenance for the flow meter to operate effectively. It would be best to choose a flow sensor with more minor moving parts to obtain accurate results and spend less on maintaining the device.
3. The temperature of the fluid
The liquid, gases, steam, or fluids measurements occur under low, high, or medium temperatures. You need to know the temperature level under which you want to measure your substance to know the best flow sensor, giving you the most accurate results of your measurements.
For example, steam measurement occurs at higher temperatures; hence it requires a flow sensor like a vortex, which can measure the flow of gases, liquids, and steam at a higher temperature and obtain the most accurate results.
4. The size of the pipe
Different flow sensors require different types of pipe sizes in measuring the fluid flow. Some flow sensors can give the most accurate results when measuring the flow rate in small pipes. E,g, positive displacement flow meters.
On the other hand, some ultrasonic sensors will only give accurate results when measuring the fluids in pipes with big diameters of more than six inches, depending on their designation structure. So you should know the size of your line where the fluid is to be measured to know the perfect flow sensor for accurate results.
5. Environmental area of operation
Some flow sensors do not give accurate results of fluid measurements under certain environmental conditions like changes in humidity and temperature affect the working standard of the flow sensor. For example, you can break a thermal flow sensor when using hot-wire anemometers on it.
Ultrasonic flow sensors also use sound waves to measure the flow rate, so they cannot give accurate results where there is noise pollution that you cannot bear. If you choose a flow that doesn’t suit your demographic, you will have to spend more on maintenance costs.
6. The cost of the flow sensors
Various flow sensors cost differently depending on their efficiency and effectiveness in system operations. The advantages and disadvantages of each flow sensor vary from one to one. The cost of the flow sensor can help you know if the flow sensor is perfect for your operation or not.
The installation and maintenance costs are always vital in helping you know the perfect flow sensor for your operation. Flow sensors with fewer moving parts cost less when it comes to maintenance costs, while those with more moving parts that interfere with the measurement reading require frequent maintenance hence costing more.
Knowing the perfect flow sensor for your measurements will help you obtain the most accurate results since you will consider one over the other depending on the factors like the fluid type, pipe size, and temperature variations.
