Working Principle of Industrial Flanged Magmeters
The industrial flanged magmeter operates based on Faraday's Law of Electromagnetic Induction, which states that when a conductive liquid or gas passes through a magnetic field, it generates a voltage proportional to the flow velocity. Here’s how it works step-by-step.
- Magnetic field generation: Inside the magmeter, a pair of coils generates a magnetic field across the flow tube.
- Flowing conductive fluid: As the conductive fluid (such as water, slurry, or chemicals) flows through the meter, it cuts through the magnetic field created by the coils.
- Voltage induction: According to Faraday’s Law, the motion of the conductive fluid generates a small voltage, which is directly proportional to the velocity of the fluid flow.
- Electrode detection: Electrodes inside the magmeter detect this induced voltage. The voltage magnitude is measured, which is then used to calculate the flow rate.
- Output signal: The meter transmits the flow rate as an electrical signal, typically in the form of a 4-20mA output or a pulse, which can be monitored and recorded by connected systems.
