Magnetic flowmeters are known for their high accuracy and low maintenance Posted by : admin / Posted on : Jan 18, 2023

A magnetic flowmeter, also known as a magmeter, is a type of flowmeter that is used to measure the flow rate of conductive liquids. It works on the principle of the Faraday's law of electromagnetic induction, which states that a voltage is induced in a conductor moving through a magnetic field.

The magmeter consists of two main components: the sensor, which is installed in the pipe and detects the flow, and the transmitter, which is responsible for interpreting the signal from the sensor and providing an output that can be read by a user.

The sensor is made up of a pair of electrodes, which are installed on the inside of the pipe, and a magnetic field is created between them. As the conductive liquid flows through the pipe, it generates a small electrical current that is proportional to the flow rate. This current is detected by the electrodes and sent to the transmitter, which converts it into a flow rate that can be read by the user.

Magnetic flowmeters are suitable for measuring the flow of conductive liquids such as water, acids, and alkalis. They are often used in industrial applications such as chemical processing, water treatment, and mining. They are also used in wastewater treatment plants, power plants, and other industrial environments.

Magnetic flowmeters are known for their high accuracy and low maintenance, they are also suitable for high-pressure and high-temperature environments. They can also be used for bidirectional flow measurements and can be used in both clean and dirty fluid conditions. However, they are not suitable for non-conductive liquids such as oil, gas and some chemicals.
