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 INSTRUMENTS MAKE are micro-controller based full bore type electromagnetic flow meters specially used for variousindustrial applications. These flow meters accurately measure the flow rate of conductive liquids and slurries in closed pipes. Due toits simple and rigid design, the flow meter is an obstruction less and maintenance-free instrument in place of conventionalmechanical flow measuring devices. The use of ‘Pulsed DC’ technology offers highest ability and better measuring accuracy in theform of electrical signal 4-20 mA DC linearly proportional to volumetric flow. The instrument is based on Faraday’s law ofelectromagnetic induction. A magnetic field is generated by the instrument in the flow tube. The fluid flowing through this magneticfield generates a voltage that is proportional to the flow velocity. Corresponding electrical output is provided with respect tomeasuring flow range

A pressure switch is a mechanical or electronic device that is activated when a certain threshold or setpoint is reached by the process fluid’s pressure. The pressure switch can differ depending on whether it consists of a bourdon tube, piston, diaphragm, or membrane that moves or deforms depending on the degree of pressure applied by the system. For example, an air pressure switch is used to maintain a constant pressure and can turn the compressor off once the tank reaches the required air pressure level. If the air pressure drops and more is required, the switch can also turn the compressor on.

A flame arrester functions by absorbing the heat from a flame front thus dropping the burning gas/air mixture below its auto-ignition temperature; consequently, the flame cannot survive. The heat is absorbed through channels (passages) designed into an element.

“NRG GLOBAL” make Magnetic Level Gauge provides clear, high clarity indication of liquid level. Magnetic Level Gauges are principally designed as an alternative to glass level gauges. NRG GLOBAL offers Magnetic Level Gauges in top-bottom, top and side mounted construction with two types of indicator system i.e. Capsule and Bi-colour Rollers. Magnetic Level Gauge is consists of three major components: Float Chamber, Float and Indicator System. Magnetic Level Gauge operates on the principle of magnetic field coupling to provide Fluid Level Information. Float chamber is typically constructed with nonmagnetic pipe having process Connections that matches to the vessel connections. Float size and weight is determined by the process fluid, pressure, temperature and the specific gravity of the process fluid. Float contains magnets to provide 360 ̊magnetic flux field.

Conductivity Level Switch is a simple, low cost, point level measurement switch designed for level detection of conductive liquids having low densities, high viscosities, containing solid particles and to detect interface between non-conductive and conductive liquids. The probes work through the variation of the electrical resistance between the reference electrode and the level-control electrode. Conductivity level switches detect the level resistance when their electrodes are covered by the medium. If the tank is made of plastic, concrete, or any other nonconductive material, an additional electrode is required as a reference Conductivity Level Switches are available with stainless steel 316 electrodes as standard Suitable for many chemicals and aggressive media which are conductive in nature and dirty liquids, liquids with high solid content Construction available with both Solid probes & Suspended probes to suit fitting requirement It is a simple, low cost, point level controller designed for detecton of conductive liquids, having low densites, high viscosities, containing solid particles and interface between nonconductive and conductive liquids. CONSTRUCTION & OPERATION It comprises of a probe, wired to a level controller. The probe holds one common reference/common electrode and one or multiple “Control Electrodes” depending upon the number of levels to be controlled. All the electrodes are suitably insulated to avoid electrical bridging. The lengths of “Control Electrodes” correspond to the height of preset level points to be controlled and the length of the “reference/common Electrode” is kept slightly longer than the longest “Control Electrode”. If tank is conductive, it can be used as a reference/common electrode. Then number of control electrodes equals number of preset levels. Level controller houses sensing electronics consisting of power supply and signal conditoning circuit which provide a “Low AC Voltage” across mass and control electrodes. On liquid reaching preset level point electrical circuit gets completed - generating a signal which is amplified to actuate a relay, those potential free contacts are available for subsequent operations. On “Level Falling” the circuit breaks, deactivating the relay Additional Information: Production Capacity: 100 Delivery Time: WEEK Packaging Details: EXPORT WORTHY PAKING

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.
