Magnetic type flow meter
Description:
A magnetic flow meter, also known as a magmeter, is a type of flow meter that measures the flow rate of conductive fluids. It operates based on the principle of electromagnetic induction.
The magnetic flow meter consists of a pipe or a conduit through which the fluid flows and a pair of electrodes placed on opposite sides of the pipe. The electrodes are in contact with the fluid and are connected to an external power source. When the fluid flows through the pipe, a magnetic field is generated by passing a current through the fluid and perpendicular to the electrodes.
As the conductive fluid moves through the magnetic field, it induces a voltage in the fluid, which is detected by the electrodes. The induced voltage is directly proportional to the velocity of the fluid, allowing the flow meter to calculate the flow rate accurately.
One of the significant advantages of magnetic flow meters is their ability to measure the flow of a wide range of conductive fluids, including corrosive liquids, slurries, and wastewater. They are not affected by the fluid’s density, viscosity, or temperature, making them versatile and suitable for various industries, such as water treatment, chemical processing, and food and beverage.
Additionally, magnetic flow meters are non-intrusive, meaning they do not obstruct the flow or create pressure drops, making them highly reliable and low maintenance. They provide accurate and stable measurements over a long period, making them a popular choice for flow rate monitoring and control in industrial processes.
