The key to the success of buoyancy instruments is the means by which the motion of the liquid and, therefore, the float or displacer is converted into the desired level control action. Magnetrol incorporates the optimal features into its level switches while providing repeatable, dependable performance. The result of completely isolating the process environment from the switching mechanism and keeping all magnetic components out of the process environment, is a robust, versatile instrument suitable for a wide variety of control applications. The float orientation utilized for top mounted switches and as the primary sensing method for external cage switches is the vertical float. The principle of operation is simple and provides a practical solution to narrow level differential requirements. A rigid stem and attraction sleeve assembly is affixed to the top of a spherical or oblong float. The size of the float determines the buoyancy force of the process liquid against the float, stem and sleeve assembly. This buoyancy force must be greater than the weight of the assembly and is increased by enlarging the float. Because the buoyancy force is greater, the float assembly rises directly with the liquid level. As it does so, the attraction sleeve moves within a static pressure boundary, the enclosing tube. A permanent magnet is attached to the switch assembly outside of the enclosing tube. When the attraction sleeve enters the field of the switch magnet, the magnet is pulled toward the sleeve, snapping against the enclosing tube and causing the switch to change state. As the liquid level falls, the float/stem/sleeve assembly follows it. When the attraction sleeve moves out of the field of the switch magnet, a return spring on the switch mechanism pulls the magnet away from the enclosing tube, returning the switch to its original state. T Buoyancy Technology’s Advantages: + Service pressures up to 5000 psig (345 bar) + Service temperatures to +1200° F (+649° C) + No calibration of switches + Setup of displacer switches without level change + Highly reliable and familiar technology + Multiple stage control available + Narrow and/or wide differential displacer switches + Transmitters available for continuous output + Switches do not require power Buoyancy Technology’s Limitations: - 4 Buildup or dirty process may impede performance. Switch accuracy limited to ±0.25 inches (6 mm). Not suitable for solids Moving parts in process Horizontal Float A horizontal float switch, often called a side mounted Displacer Switches While taking advantage of the same buoyancy and unit, operates much like a vertical float. It utilizes the same components, float, stem, sleeve, enclosing tube, magnetic coupling principles as float switches, displacer level switches utilize a precision range spring to con- slightly different manner. The lower float stem pivots vert the change in buoyancy force to movement of an attraction sleeve. Because the displacer is weighted, on a fulcrum. This means that as the float rises, the it hangs into the liquid rather than floating on top. As attraction sleeve is pulled down out of the field of the the liquid level moves changing the volume of liquid switch magnet causing the magnet to be pulled away displaced by the displacers, the buoyancy force on the from the enclosing tube. Conversely, as the float falls, displacers changes. This causes elongation or compres- the sleeve moves upward causing the switch magnet to sion of the range spring which, in turn, moves the pull in. Side mounted controls may be used for wide attraction sleeve into or out of the field of the switch magnet, changing the state of the switch. switch magnet and mechanism, but functions in a level differential. By lengthening the float stem, the liquid level and float must move through a greater distance in order to change the state of the switch. Side mounted units offer the option of mounting toward the bottom of a vessel for use in low level service, something that may not be done with a top mounted vertical float. Displacers 5 Buoyancy Level Controls (continued) Displacer Transmitters As with displacer switches, the change in buoyancy spring compresses or elongates, the core moves within force on a range spring is converted to motion in a dis- the LVDT windings, inducing currents in the secondary placer transmitter. This motion is used to produce an windings. This information is processed and output as a output proportional to the change in liquid level. The 4–20 mA proportional signal.
