'narrow level differential applications'

Float level switches All float operated liquid level controls operate on the basic buoyancy principle which states "the buoyancy force action on an object is equal to the mass of liquid displaced by the object." As a result, floats ride on the liquid surface partially submerged and move the same distance the liquid level moves. Because of this, they are normally used for narrow level differential applications such as high level alarm or low level alarm.

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. FEATURES: • Wide choice of switching functions • Suitable for large tanks up to 15 meters • Site adjustable switch points • Customized for high temp, high pressure & vaccum applications. • Reliable performance in turbulent liquids even without still pipes. • Easy transportation of longer length switches. • Enclosure : Weather proof-IP-65 Ex-proof-Gr.

“NRG GLOBAL” Top Mounted Magnetic Gauge is mounted on top of the tank by a suitable process connection preferably 100 mm NB flange. A float designed for the liquid to be gauged is guided within a stilling well that rest on the process flange. The float is connected to a stem that has a magnet at the upper end moving in a chamber. The float along with the stem and magnet moves up and down with the changing in liquid levels in the vessel. On the dry side of the chamber is the Magnetic Follower Display assembly comprising of a Red & Black PP magnetic capsule housed in a glass tube filled with water. As the float tracks the liquid level the magnet inside the float magnetically couples the Red & Black PP capsule and the capsule will remain magnetically coupled and the level can be read off directly TECHNICAL FEATURES •Simple and robust design. •Pressure and gas proof separation of chamber and display. •Measuring and indication of the level of aggressive, combustible, toxic, hot agitated and contaminated liquids. •Magnetic Follower display without external power. •Available for applications in all areas of industry through use of highly corrosion resistant materials •Designs for a pressure range from full vacuum to 30 bar •Designs for a temperature range from 100C to 250O C •Food industry design. •Interface measurement. OPTIONS: “NRG GLOBAL” Magnetic Switches are used to monitor certain limits of the level.
