NRG GLOBAL INSTRUMENTS MAKE Electromagnetic Flow Meters, simply known as mag flow meter is a volumetric flow meter which is ideally used for waste water applications and other applications that experience low pressure drop and with appropriate liquid conductivity required.The device doesn’t have any moving parts and cannot work with hydrocarbons and distilled water. Mag flow meters are also easy to maintain.Electromagnetic Flow Meters Principle of Magnetic Flow Meter Based on Faraday’s LawMagnetic flow meters works based on Faraday’s Law of Electromagnetic Induction. 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. [E is the voltage generated in a conductor, V is the velocity of the conductor, B is the magnetic field strength and L is the length of the conductor].It is very important that the liquid flow that is to be measured using the magnetic flow meter must be electrically conductive. The Faraday’s Law indicates that the signal voltage (E) is dependent on the average liquid velocity (V), the length of the conductor (D) and the magnetic field strength (B). The magnetic field will thus be established in the cross-section of the tubeBasically when the conductive liquid flows through the magnetic field, voltage is induced. To measure this generated voltage (which is proportional to the velocity of the flowing liquid), two stainless steel electrodes are used which are mounted opposite each other.The two electrodes which are placed inside the flow meter are then connected to an advanced electronic circuit that has the ability to process the signal. The processed signal is fed into the microprocessor that calculates the volumetric flow of the liquid.Electromagnetic Flow Meters Formula:Electromagnetic flow meters use Faraday’s law of electromagnetic induction for making a flow measurement. Faraday’s law states that, whenever a conductor of length ‘l’ moves with a velocity ‘v’ perpendicular to a magnetic field ‘B’, an emf ‘e’ is induced in a mutually perpendicular direction which is given byThus the volume flow rate is proportional to the induced emf. In Practical applications we have to enter the meter constant ‘K’ value in magnetic flow meter which is available in vendor catalog/manual.Applications of Magnetic Flow MetersThis electromagnetic flow meter being non intrusive type, can be used in general for any fluid which is having a reasonable electrical conductivity above 10 microsiemens/cm.Fluids like sand water slurry, coal powder, slurry, sewage, wood pulp, chemicals, water other than distilled water in large pipe lines, hot fluids, high viscous fluids specially in food processing industries, cryogenic fluids can be metered by the electromagnetic flow meter Additional Information: Production Capacity: 100 Delivery Time: EX STOCK Packaging Details: EXPORT WORTHY PACKING

NRG GLOBAL MAKE Displacer type level switches offers the industrial user a wide choice of alarm and control configuration. DLS works on a simple buoyancy principle and is well suited for simple or complex applications, such as forming surging liquids or agitated fluids, and usually costs less than other types of level switches. CONSTRUCTION & OPERATION Operation is based on simple buoyancy principle. As the liquid level rises and progressively immerses the displacer elements, the effective weight suspended on the spring reduces and the consequent length of the spring change is used to provide magnet movement and operate the switch. The spring movement causes the magnetic sleeve to attract a pivoted magnet actuating a switch mechanism located outside the barrier tube. Built-in limit stops, prevent over stroking under level surge conditions. FEATURES: • Wide choice of switching functions • Suitable for large tanks up to 15 meters • Site adjustable switch points • Customized for high temp, high pressure & vaccum applications. • Reliable performance in turbulent liquids even without still pipes. • Easy transportation of longer length switches. • Enclosure : Weather proof-IP-65 Ex-proof-Gr.
