The composition and some functions of electromagnetic flowmeter

2024-10-28

As an instrument used to measure the flow of conductive liquids, the Electromagnetic Flowmeter has some key elements in its composition and function.

1. Measuring pipe

The core of the Electromagnetic Flowmeter is the measuring pipe through which the fluid passes. Typically, measuring pipes are made of materials with good electrical conductivity to ensure accurate electromagnetic induction measurements.

2. Electromagnetic coil

The electromagnetic coil is an important part of the Electromagnetic Flowmeter, which generates a magnetic field by energizing it. This magnetic field passes through the measurement pipe and interacts with the conductive material in the fluid to generate an induced electromotive force.

3. Electrodes

Electromagnetic flow meters usually contain two electrodes, located on both sides of the measurement pipe. As a conductive fluid flows, the electrodes sense changes in the electromotive force in the fluid, and this change is measured to calculate the flow rate.

4. Converter

The converter of the Electromagnetic Flowmeter is responsible for processing the electromotive force signal induced by the electrode and converting it into a readable digital or analog output. This step is the key for Electromagnetic Flowmeter to achieve flow measurement.
