Before you draw conclusions about the best flow meter for industrial use, you need to understand what they are and how they work. The turbine flow meter consists of rotor blades that are arranged at an angle on a shaft. The liquid flowing through the blades causes the rotor shaft to rotate. The rotation of the shaft is recorded by a mechanical reader. With the blades, a magnetic reader detects movements through magnetic impulses. The movement of the blades and the rotor is proportional to that of the liquid. This is ideal for gas and liquids. Special considerations are made for non-lubricating liquids. The blades are generally greased when the instrument is to measure this fluid. When measuring natural gas transmission, the blades can only withstand temperatures up to 60 degrees Celsius.

A turbine flow meter is ideal for clean and caustic liquids. This includes chemicals, oil, and water. The pipe size should not exceed 24 inches in diameter. For large flow meters, the installation requires a solid concrete base. The accuracy of the turbine flow meter decreases if the flow rate is too low. On the other hand, it is not possible to use this type of meter for liquids that flow at high speed. This consumes the rotor blades or damages them completely.

The magnetic flow meter, in turn, measures the flow of liquid according to a concept known as Faraday’s law. The meter does not contain any moving parts. The scientific law is based on the principle that liquid particles when they move through a magnetic field, generate a voltage that is proportional to their speed. An electronic reader collects this signal and processes it. In contrast to the turbine counterpart, this instrument is ideal for measuring dirty liquids, strongly caustic acids, and water. However, it cannot be used for hydrocarbons and distilled water.

Due to its discrete nature, a magnetic flow meter can be used in a variety of applications. It can measure the transfer of clean, dirty, abrasive and caustic liquids. Gases are the only exception as they are not conducive. These tools work best in situations where little maintenance is required. They are the best option for pressure drops in liquids. Most industrial applications release dirty water as part of their waste. This applies to paper processing, energy production, mineral processing, and the chemical industry. Water and wastewater users use this type of meter.

Consistent with the previous discussion, magnetic flow meters are the best choice for industrial use. The meters can measure the flow of any type of liquid, clean or dirty. Most industries use water or chemicals in different ways. You need an accurate means of measuring the inflow and outflow. It should always be filled with the liquid to be measured.

Magnetic flow meter applications

There are various types of magnetic flow meters in the market. Each of these devices has different applications, but they have one thing in common, all follow the philosophy of Faraday’s law. Since different magnetic inductive flow meter have different applications, it is extremely important to choose the right unit and use it correctly to ensure that the liquid measurement project is carried out successfully. Factors to consider when choosing these measurement tools include reliability, accuracy, cost, ease of use, etc.

Now let’s talk about the different uses of this flow measurement tool. What a magnetic flow meter does depends on factors such as the physical properties of the device. Here the term physical characteristic is used for factors such as size and body weight. These factors affect the speed range of the machine and the processing capacity. You can go to for more details and information on magnetic flow meters.

The caliber dimensions of these units range from 0.6 to 7.9 inches. In contrast, the speed of these devices is between 0.98 and 32.8 feet per second. The dimensions of a measuring device and its speed capacity always remain directly proportional to each other. In addition, a large, high velocity meter can measure a larger flow rate than a small, low velocity meter. One of the most impressive features of these measuring instruments is that they often measure the flow rate of liquids and sludges very effectively under corrosive conditions. In addition, a magnetic meter is used to measure the flow rate of various corrosive materials. With these machines, you can also measure the flow rate of paper pulp and similar materials with extremely low flow rates.

These measurement tools provide more accurate results when applied to circular arrays. They tend to be relatively inefficient when measuring on rectangular tubes. Wondering if these devices can effectively measure the speed at which an explosive liquid or fuel flows? Yes, they certainly offer the possibility to measure the flow rates of such liquids. No other type of meter can perform such work with the same effectiveness as a magnetic inductive flow meter. However, when participating in such projects, you must ensure that the explosion-proof flow meter housings are ready for your own safety. To make the situation less dangerous for users, electronic remote controls can be used.
