Description
Tek-Flux 1400A Electromagnetic Flow Meter
Electromagnetic flow meters are also called as Mag-meters. It is a contact instrument used for measuring the volumetric flow rates of any fluids that can adequately conduct electricity in closed pipelines. These instruments are highly accurate, reliable, and stable devices that are used in various high-pressure industrial processes.
Measuring Principle
The Tek-Flux 1400A flow meter operates on the principle of Faraday’s Law of Induction. According to this principle, any change in the magnetic flux linked to an electric circuit causes an electromotive force (or voltage) to be induced in this circuit. The induced voltage is therefore directly proportional to the rate of change of magnetic flux with time.
Operation
The flow meter typically consists of two electromagnetic coils that are mounted on opposite sides of a non-magnetic measuring tube. Two electrodes are fitted inside the tube to detect the voltage generated by the conducting fluid. Although these electrodes come into contact with the fluid, they do not obstruct its flow. When current is applied to the coils, they generate an alternating magnetic field across the cross-sectional area of the tube. A fluid flowing through the magnetic field acts as a conductor, and a voltage is induced. The induced voltage is picked up by the electrodes and sent to a transmitter that is either mounted on the flow meter or connected remotely. The transmitter calculates the volumetric flow rate and displays the output.
