electromagnetic flowmeter

An electromagnetic flow meter, also known as a magnetic flow meter, is a type of flow measurement device used to measure the flow rate of conductive fluids. It operates based on the principle of electromagnetic induction.
The operation of an electromagnetic flow meter is as follows:
When a conductive fluid flows through the flow tube, it acts as a conductor moving through the magnetic field generated by the coils.
The fluid’s motion induces a voltage across the electrodes, which is proportional to the flow rate.
The induced voltage is measured by the receiver coil and converted into an electrical signal.
The electrical signal is processed by the transmitter, which determines the flow rate based on the voltage and provides an output signal or display.
The advantages of electromagnetic flow meters include their ability to measure a wide range of conductive fluids, including corrosive and abrasive liquids. They have no moving parts, resulting in minimal pressure drop and low maintenance requirements. Additionally, they offer high accuracy and can measure bidirectional flow.
It’s important to consider factors such as fluid conductivity, flow rate range, pipe size, and compatibility with the fluid when selecting an electromagnetic flow meter for a specific application.
