What are the uses of electromagnetic flow meter?
What are the uses of electromagnetic flow meter?
The main use for magnetic flow meters is for measuring the flow rate of conductive fluids and dirty liquids. Though these are two primary functions, they are also used for measuring volumetric flow for other fluids due to the fact that they are easy to maintain and do not have moving parts.
What is the principle of working of a magnetic flow meter what are its advantages over other types of flow meters?
A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. The physical principle at work is electromagnetic induction.
What is the working principle of electromagnetic flow meter?
PRINCIPLES. Electromagnetic flow meters detect flow by using Faraday’s Law of induction. Inside an electromagnetic flow meter, there is an electromagnetic coil that generates a magnetic field, and electrodes that capture electromotive force(voltage).
What are the advantages and disadvantages of magnetic flow meter?
It can only measure the liquid flow of conductive medium, and can not measure the flow of non-conductive medium, such as gas and water for better heat treatment. In addition, the lining needs to be considered under high temperature conditions.
Which of the following is applicable for the electromagnetic flow meter?
5. Which of the following is applicable for the electromagnetic flow meter? Explanation: Electromagnetic flow meters don’t cause obstruction to flow and can be used for measurement in slurries. 6.
What are the advantages of positive displacement flow meters over inferential flow meters?
18.27 Types of Flow Meter
| Type | Typical pipe diameter (D) range (mm) | Typical repeatability (\% of full scale) |
|---|---|---|
| Electromagnetic | 25–2500 | 0.1 |
| Ultrasonica | Up to 7000 | 0.5 |
| Coriolis | 15–80 | |
| Vortex | 15–300 | 0.2 |
What are the limitations of electromagnetic flow meter?
(1) The application of electromagnetic flow meter has certain limitations. It can only measure the liquid flow of conductive medium, and can not measure the flow of non-conductive medium, such as gas and water for better heat treatment. In addition, the lining needs to be considered under high temperature conditions.
What are the applications of positive displacement flow meter?
Applications of positive displacement flow meters: Measuring volumetric flow of liquids/ fluids in pipes. Chemical industries to accurately estimate the flow of viscous fluids and various chemicals, hydrocarbons, and cryogenic liquids. Measuring individual flow of liquids in a two component mixer.
