WT4300E Electromagnetic flowmeterDetailed product description：

Overview
The WT4300E electromagnetic flowmeter (EMF) can be used to accurately measure the flow rate of liquids, pulp, slurry, and slurry with conductivity greater than 5 μ S/cm. The WT4300E integrated type is a flow measurement system designed with sensors and signal converters integrated, while the WT4300E split type is a system where sensors and signal converters are installed separately.

working principle
The basic principle of electromagnetic flowmeter is Faraday's law of electromagnetic induction. When a conductor cuts magnetic field lines, an induced electromotive force will be generated inside the conductor.
This principle is used to measure the flow of conductive fluid inside a tube, and the direction of fluid flow is perpendicular to the direction of the magnetic field.
The induced electromotive force generated in the fluid is picked up by a pair of electrodes located at the radial ends of the tube, and the signal voltage is proportional to the magnetic field strength, the distance between the electrodes, and the average flow velocity.
Due to the constant magnetic field strength and electrode distance, the signal voltage is directly proportional to the average flow velocity. The formula for calculating volumetric flow rate indicates that the signal voltage is linearly proportional to the average flow velocity.
In a signal converter, the induced signal voltage is transformed into programmable analog and digital output signals.
