Electromagnetic Flow Meter

The Faraday law of electromagnetic induction is a principle that is used by the electromagnetic flow meter to calculate the volume flow of conductive liquids. There are lots of advantages of an electromagnetic flow meter.

These obstruction-free, uni- or bi-directional volumetric flow meters, also known as mag meters or electromagnetic flow meters, can be used in a variety of field applications. Mag meters are frequently used because of their prowess in handling complex flow tasks involving electrically conductive liquids and fluids.

Electromagnetic Flow Meter Working

The electromagnetic flow meter works on Faraday’s law of electromagnetic induction. A transmitter and a sensor are used in magnetic flow meters to detect the induced voltage produced by the movement of fluid through a pipe. In order to communicate a flow measurement to a control system, the transmitter translates the voltage produced by the sensor into a flow measurement.

According to Faraday's Law, a conductive fluid will generate an electric signal within a conductor as it moves through a magnetic field that is directly proportional to the process fluid's flow rate in the magnetic field.

E = k*B*D*V is the mathematical formula for this law. The flow velocity of the fluid moving through the magnetic field (V) and the induced voltage (E) is exactly proportional (B).

When measuring the displacement or bulk movement of liquids in an application, liquid flow meters are crucial. The electromagnetic flow meter is one of several types of flow measurement equipment that is available. After differential pressure and positive displacement flow meters, it is regarded as the third most common form of the meter.

These flow meters, sometimes referred to as mag meters or electromagnetic meters, are highly common in a variety of industrial and commercial applications because of their many benefits. Let's look at some of their unique features.

The amount of liquid, gas, or vapor that travels through flowmeters is measured. Some flowmeters gauge flow by counting how much fluid travels through them over a predetermined period of time (such as 100 liters per minute). Other flowmeters calculate the total volume of fluid that has been processed by the device (such as 100 liters).

Advantages of Magnetic Flow Meter

In virtually every business, magnetic flow meters are the best option for measuring electrically conductive liquids, including:

• Water
• Wastewater
• Chemical/Petrochemical
• Food & Beverage
• Oil & Gas

The advantages of an electromagnetic flow meter are as follows:

Mag meters are quite good at handling liquids of all kinds and concentrations, and they offer the following distinctive advantages of electromagnetic flow meter:

Even in corrosive environments, these flow meters can accurately detect the displacement of liquids. Hence, they are helpful in quantifying corrosive substances such as slurries and abrasives.

• Electromagnetic flow meters have a very good accuracy rate.
• They are useful for determining the liquid flow rate of explosives or combustibles.
• Mag meters are energy-efficient because they consume very little electricity.
• Almost any water-based substance as well as the majority of acids and bases can have their flow rate measured using these; The flow of liquids may be accurately measured by electromagnetic liquid flow meters in both upstream and downstream directions. They are able to monitor liquids with both low and large-volume flow rates.
• The electromagnetic flow meter has a straightforward sensory architecture and uses little energy. There are no moving parts in the measurement tube of the meter. It also lacks any adjustable components that can hinder the passage of fluids through it. Moreover, as fluid flows through the device, no pressure is lost.
• Accuracy: The electromagnetic flow meter gadget accurately detects suspended liquid-solid two-phase flows, sloping medium flows, and corrosive medium flows. This is due to the absence of obstructive flow components inside the measuring tubes. Just the electrode and the measuring tube's liner come into contact with the flowing fluids.
• Electromagnetic flow meter for use in hospitals
• The instrument is a volumetric measurement instrument. Within a certain range of electrical conductivity, the density, viscosity, and temperature of the medium being tested have no impact on the device throughout the measuring process. The device measures the flow rates of various conductive liquids after being calibrated with water.

Other Advantages of Magnetic Flow Meter:

• Being able to gauge how well liquids are moving through it in reverse
• Appropriate for solid hydraulic transportation
• Offers a broad linear range
• There are improvements to the measurement range setting.

Applications of Magnetic Flow Meter

Because of all the aforementioned advantage, there are various applications of electromagnetic flow meters:

• They are helpful for measuring the amount of potable water.
• These may be used to measure the flow of slurries at building sites.
• They are helpful in measuring the flow rate of combustible fuels in petroleum processing facilities.
• They are helpful for determining how much explosive liquid, paint, and abrasives are displaced.
