Electromagnetic flowmeter: Flow measurement for liquids
Electromagnetic flowmeter: Flow measurement for liquids
An electromagnetic flowmeter is a flow-measuring device for conductive fluids. It operates on the basis of Faraday's law, generating an electrical signal proportional to the flow rate of the fluid passing through its magnetic field. With no moving parts, it provides accurate measurement, is easy to maintain and is suitable for a variety of industrial applications.
Electromagnetic flow meters for liquid flow measurement
Simple, economical flowmeter for conductive liquids
Electromagnetic flowmeters are ideal for measuring the flow of all liquids with a minimum conductivity of 5 μS/cm (20 μS/cm for demineralized water).
These electromagnetic meters are highly accurate, and the measurement of volume flow is not dependent on the density, temperature or pressure of the medium.
Measurement principle of electromagnetic flow meters
The measurement principle of electromagnetic flowmetersis based on Faraday's law:
The voltage induced by a conductor moving through a magnetic field is directly proportional to the conductor's speed.
The induced voltage is measured across two diametrically opposed electrodes.
This voltage is proportional to the magnetic field, the distance between the two electrodes and the average fluid velocity.
High accuracy: Electromagnetic flowmeters offer exceptional accuracy, capable of detecting the smallest flow variations. This enables reliable, consistent measurement, essential for critical industrial applications.
Reliability: With no moving parts, these magnetic meters require little maintenance and guarantee a long service life. Their robust design makes them particularly well suited to demanding industrial environments.
Flexibility: electromagnetic flowmeters can measure a wide variety of fluids among liquids. This versatility makes them an ideal choice for many industrial applications.
Safety: Using the principle of electromagnetic induction, ATEX electromagnetic flowmeters ensure maximum safety in sensitive environments and processes where there is a risk of explosion or fire.
