Electromagnetic flow meter is a volumetric flow meter which measures the flow of liquid by the induced voltage across liquid by its flow through a magnetic field using faraday s law of induction where no moving part makes it ideal for wastewater applications or any dirty liquid which is conductive or water based.
The magnetic flow meter construction consists of an electrically insulated or non conducting pipe such as fibre glass with a pair of electrodes mounted opposite each other and flush with the inside walls of the pipe and with the magnetic coil mounted around the pipe so that a magnetic field is generated in a plane mutually perpendicular to the axis of the flow meter body and.
The induced voltage is carried to the transmitter through the electrode circuit.
A magnetic field is applied to the metering tube which results in a potential difference proportional to the flow velocity perpendicular to the flux lines.
A magnetic flow meter mag meter electromagnetic flowmeter is a transducer that measures fluid flow by the voltage induced across the liquid by its flow through a magnetic field.
The magnitude of the induced voltage e is directly proportional to the velocity v of the conductor width l and b being the strength of the.
Principle of magnetic flow meter based on faraday s law.
According to this principle when a conductive medium passes through a magnetic field b a voltage e is generated which is proportional to the velocity v of the medium the density of the magnetic field and the length of the conductor.
