Electromagnetic Flowmeter -

1. Overview

Walsn SX Series magnetic flowmeter is ideal for highly reliable detection of conductive liquids in a wide variety of application. It uses advanced excitation technology which assures efficient measurement. Users can also benefit from flexible options without spending a lot money.

2. Operation Principle

The operating principle of the electromagnetic flowmeter is based of Faraday's Law of induction. When a conductive liquid passes through the flowmeter tube axis, the magnetic field lines are cut by the liquid. This results in induction potential, which is detected by the two electrodes installed in the tube wall perpendicular to the measuring tube axis and the magnetic field.

The induction potential is proportional to the magnetic induction, the distance between two electrodes, and the average flow rate of fluid. Since the magnetic induction and the distance between two eletrodes are constant, the signal voltage is proportional to the average flow rate.
