Operating Principle of Float and Displacer Level Switches and Sensors
Float level switches and sensors operates based on Archimedes principle. The apparent weight of a floating object is reduced by the weight of the liquid displaced. Archimedes’ principles states that the buoyant force acting on an object equals the weight of the fluid displaced. As the level changes around the float and displacer materials, the buoyant force varies in proportion and can be detected as an indication of level. Floats are commonly used for point level indication while displacers can be used for continuous as well as point level indication.
Design of Float and Displacer Level Switches
The buoyant force available to operate a float level switch is the difference between the weight of the displaced fluid (gross buoyancy) and the weight of the float.
Floats and displacers are available in spherical, cylindrical and a variety of other shapes. Standard float sizes are available from 1 to 5 inches in diameter. Custom float sizes, shapes, and materials can be ordered from most manufacturers. They can be made out of stainless steel, Teflon, Hastelloy, Monel, and various plastic materials.
Floats should always be lighter than the minimum expected specific gravity, SG, of the process fluid. For clean liquids a 0.1 SG difference is desirable, while for viscous or dirty applications a difference of at least 0.3 SG is recommended. This allowance provides additional force to overcome the resistance due to friction and material build-up. In dirty applications, floats should also be accessible for cleaning so as to increase the efficiency and effectiveness of the float mechanism.
Floats can be attached to mechanical arms or levers and can actuate
