1. PRODUCT DESCRIPTIONNRG 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 OPERATIONWhen 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 deadload is dynamically balanced by the differential pressure.

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.
