Description

Product Composition

The electromagnetic flowmeter is composed of two parts: the electromagnetic flow converter and the electromagnetic flow sensor. The separate type also needs two dedicated double-layer shielded cables to connect the converter and the sensor.

Product type

The series of electromagnetic flow meters are divided into two structural forms: integrated type and separate type. It can be used in specified explosion-proof places.

The sensor is available in 7 different materials for the electrodes and 4 different materials for the lining.

●Can be used in corresponding explosion-proof occasions.

Working principle

Mathematical physical model

The working principle of the electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductor moves in a magnetic field, an induced electromotive force will be generated at both ends of the conductor perpendicular to the direction of the magnetic field and the direction of motion. The magnitude of the electromotive force is proportional to the velocity of the conductor and the magnetic induction of the magnetic field.
