Flow measurement is critically essential to run industrial plants efficiently. there's a cluster of flow measurement devices to live the flow of varied liquids. The magnetic flow meter is one among those devices.
Magnetic flow meter also mentioned as Mag meter, a magnetic inductive flow meter is employed to live the volumetric flow of chemical solution, paper pulp, sewage slurry, conductive fluid, etc. The magnetic inductive flow meter measures the fluid rate by the voltage induced across the liquid. It requires conductive fluid i.e. water that contains ions and a pipe with an electrically insulating surface.

Magnetic inductive flow meter or Mag meter comprises two main parts i.e. transmitter and a sensor. the mixture of those two parts measures the flow. Mag meter sensor is placed in line with the pipes because the fluid flows through the pipe induced voltage generated by the liquid is measured. This induced voltage generated by the sensor is transferred to the transmitter. The transmitter alters the voltage into a flow measurement and transmits it to the system.
The magnetic inductive flow meter measures flow according to Faraday's law of electromagnetic induction. Inductive flow meter has an intensive range of measurable rates. The ratio of the utmost flow to the minimum flow is usually 20: 1. it's suitable for a good range of commercial pipe diameters. The output is linear with the measured flow. It can measure fluids with electrical conductivity ≥5μs / cm. The magnetic inductive flow meter is employed to live abrasive fluid, salt solution, water, chemicals, sewage, pulp slurry, etc. But magnetic inductive flow meter cannot measure the flow of gas, steam, oil and pure water.

• Pharmaceutical industry – during a pharmaceutical industry critical parameters are followed to supply life-saving medicines. to regulate these parameters flow meters are wont to regulate the blending of chemicals, coloring coating of pills, defining the dimensions of pills, coating of drugs. Turbine flow meter, ultrasonic flowmeter, Coriolis flowmeter are a number of the foremost commonly used flow meters utilized in the pharmaceutical industry.
• Food and beverages industry - Electromagnetic and mass flow meter is employed to manage the flow of acids and liquids respectively with high accuracy within the food and beverages sector. Coriolis flow meter is employed to manage the flow of gases.
• Oil and gas industry – At petroleum refineries where the raw oil is processed to supply various petroleum products like diesel, petrol, kerosene oil, wax, etc. Critical measurement and analysis of the volumetric flow are required to process petroleum and produce petroleum products. Specially designed flow meter helps in regulating the volumetric flow during refining process making is safer and straightforward to work.
• Sanitary or sewage treatment plants – At sanitary or sewage treatment plants an enormous amount of liquid slurry flows through the pipes. The slurry liquid goes passes through various small filtration plants for the treatment. to manage the volumetric flow of this sewage slurry magnetic flow meter is employed at different filtration process plants for flow measurement.
There are several other applications where magnetic inductive flow meters are wont to measure volumetric flow with high precision like chemical and petrochemical industries, pulp and paper industries, industries where a highly corrosive and abrasive fluid is processed, etc.
