'average liquid velocity'

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 Tubular Level Gauge are designed for visual liquid level observation. Liquid observation is common in process industry. Tubular Level Gauge is the simplest and reliable form of level indication in atmospheric or pressurized tank applications. Tubular Level Gauges can be used to visualize the level in low or medium pressure application. NRG GLOBAL offers economical and reliable level gauges for direct reading of level in tanks / vessels. This Tubular Level Gauge consist C channel frame or tie rods, Glass tube, End blocks, and isolation valves, drain valve, Vent plug, and packing material. These level indicators are mounted on the side of the tank or vessel. These Tubular Level Indicators are mounted parallel along the tank or vessel. The level in the transparent glass tube change as the process level fluctuates. Level changes accordingly to the process level fluctuation and gives local liquid indication. Changes are directly proportional. When liquid level in tank or vessel rises level in tube rises. When liquid level in tank or vessel decreases level in tube decreases. The level of liquid inside the tank or vessel and level of liquid inside the glass tube are same. Scale mounted on C Frame of Tubular Level Gauge indicates liquid level.

nrg global instruments make U – Tube , single limb , inclined tube Manometer is the basic and mostly used style of manometer. The U - Tube manometer is a versatile, economical instrument for the measurement of pressure, vacuums or differential pressures. Pressure measurements are accomplished by balancing a vertical head of indicating fluid with the pressure to be measured. As there is no cams, gears or levers to operate in the manometer, the readings obtained are always accurate. The U Tube Manometer, have “U” shaped tube, half filled with liquid (Water / Mercury / SP Gr. 0.81). When both the tubes are open, the liquid is at the same height in each leg (Tube / Limbs). When positive pressure is applied to one leg the liquid is forced down in that leg and up in the other. The difference in the height, which is the sum of the reading above and below zero, tells you the pressure. When vacuum is applied to one leg, the liquid rises in that leg and falls in the other. The difference in the height indicates the amount of vacuum. The U Tube Manometer, consisting of two Glass Limbs. Stainless Steel / Brass Connecting fittings mounted on a metallic frame, provided with White Acrylic Scale with zero at the center. The U Tube Liquid Column Manometer we provide is used to determine Velocity and Static Pressure, Leakage, Fan Efficiency and Gas Pressure.
