'several tubes'

NRG GLOBAL INSTRUMENTS MAKE Tubular Level Gauge is used for visual liquid level indication and is the most commonly used instrument in the process industry. It is a simple and reliable device for level reading in atmospheric or pressurized tank applications. It is mounted parallel, along the side of the tank, so as to form a closed loop. As the process level fluctuates, the level in the transparent glass tube changes accordingly and gives local level indication. The Tubular Level Gauge manufactured by NRG GLOBAL INSTRUMENTS incorporates correct design, rugged construction, proper manufacturing techniques and skilled workmanship to give dependable performance and long service life. Material integrity is assured through strict compliance of chemical composition analysis in a standard laboratory.TUBULAR LEVEL GAUGE FEATURES• Choice of Tie Rod or C-Frame Construction.• With or without isolating valve.• Material integrity assured through strict compliance of chemical composition analysis in a Standard Laboratory.• H Grade Borosilicate glass tube 19/25 mm outer dia with Teflon Packing.• Glass tube an be removed online i.e. without disconnection from vessel• Standard Connection: 1/2" / 3/4" / 1" Flange drilled to ASA 150#, others on request• Aluminum/SS scale with 5 mm resolution as standard and 1 mm on request.• Drain Plug 1/2" Vent Plug 3/4" as std and drain/vent valve as optional• Safety Ball check device(optional).• Hydro test pressure: 12 KG/cm2, 100 Deg C max working temperature.• Defrost/illuminator available on request.• Tie Rod Construction is ‘light' and permits 360ºC visibility.• C-Frame construction is robust and permits observation from Front & Rear.• Both constructions are available in integral or inline arrangements.• High quality, H grade borosilicate glass tube in 19/25mm outer dia is used.• Available in single length having c/c distance = 1600 mm.

NRG GLOBAL INSTRUMENTS MAKE Glass Tube Variable Area Flow Meters (Rotameters) are intended for general in line and ByPass metering applications (i.e. for Gas & Liquid) where operating conditions are with the limitations of Glass metering tubes. These are the principle of Variable Area. The float moves freely up and down tapered borosilicate glass with fluid flow from bottom to top. The float takes up a position where buoyancy forces and the float weight are balanced in proportion to flow rate. The Vertical position of the float as indicated by scale is the measure of the instantaneous flow rate. 2. Principal of Operation When fluid or gas flows through a taper tube containing a float, a pressure difference of P1 and P2 is created between upper and lower side of the float. The float moves upwards by a force obtained by multiplying the pressure differential by the maximum cross-sectional area of the float. Due to taper tube, as the float moves upwards, the fluid passing area increases as a result of which the differential pressure decreases. Upward movement of float stops when the dead load is dynamically balanced by the differential pressure.

NRGG LOBAL MAKE Reflex Level Gauge use the R-form sight glasses. One side surface of Reflex Glass to use flat glass has several grooves for reflecting prism. The principle of the Reflex Glass is based on the difference in the refractive indices of liquid and gas or in particular of water and steam. Liquid level shows conspicuously dark hard colour for liquid space and light white colour for empty space. These Reflex series are not used with a mica shield.Reflex Level Gauge The Reflex Gauge is assembled firmly with gasket, reflex glass, cushion gasket and gauge cover on the body by U-bolts. Reflex Liquid Level Gauges, designed and built for a wide range of high temperature and high pressure applications.

NRG offers a series of Reflex level indicators. Designed to measures the level of liquid in reactor tanks. The reflex level gauge is used for the measurement of liquid level for high pressure or high temperature or toxic liquid storage tanks. The reflex level gauge has a single prism glass mounted on one side of the chamber and uses the basic optical principles of light reflection to upgrade the expression of the liquid level in the process tank. In brief, when the light strikes the area of glass covered by the liquid is allow to pass to the interior of the gauge so that the area appears dark (black). Thus the area which is vacant appears to be (silver) and can be distinguished the difference from several feet away. We are the manufacturer of the reflex level gauge in Gujarat India.

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. The Manometer will be protected with transparent acrylic front cover fix with Aluminum frame and external zero adjustment Knob / Drain Plug / Fill Plug will Be Provided
