'fluid bypass'

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.

NRG GLOBAL INSTRUMENTS Make By-pass Rotameters are suitable for flow rate measurement in 2’’ NB or 24” higher size pipes. The instrument is simple in construction and reliable in flow rate indication. The complete assembly consists of carrier rings/flanged taps, bypass line and a Rota meter as indicator. The orifice plate dimension is based on BS/ISO- 5167 specification.

“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. DESIGN FUTURE: Indicator system is consists of bi-colour rollers equipped with magnets mounted on rail inside the housing. As the level starts rising or falling magnetic float also travels with liquid level in non magnetic chamber. The magnetic interaction between magnets in float and bi-colour rollers causes each roller to rotate 180 ̊. We are providing high & low Level Switch adjustable.

Basket filters & strainers will permit the straining & filtering of a wide variety of fluids, to retain solids of almost any size. All baskets are easily removable & cleanable. Basket strainer elements can be offered in single cylinder, double cylinder, multi cylinder & pleated design depending upon requirement of application. They are constructed of filter housing, filter element supported with perforated cage, positive sealing arrangement to avoid any bypass & choice of end connections. Operation Unfiltered liquid enters the basket housing and passes down through them. Solids are retained inside/ outside of basket depending upon design and are removed when the unit is serviced.They are available with insitu backwashing arrangement, wherein removal of baskets for cleaning is not required often. Basket filters & strainers are normally supplied with spring arrangement at the top of filter element. This will ensure any type of bypassing & confirm the position of basket, even in case of reverse flow. Fluid bypass around the basket is prevented by an optional O'-Ring seal between the basket rim and the housing inside diameter.
