Fluid Level Control by Float Balls
Hollow space or solid filled materials that are suspended at the end of a lever in a cistern, tank or a boiler that mostly used to regulate the level of a liquid and mostly water are generally referred to as float balls. The float balls are made to either have a spherical or cylindrical in shape. Float balls which have a hollow space inside helps enhance their buoyancy in water or any other liquid so as to determine the liquid level. Plastic and other materials used in making the solid fill in solid float balls are supposed to be having a lower density than that of the floating liquid to enhance buoyancy and are also used for monitoring the liquid level. The floats balls mechanisms can also be utilized in other mechanisms to monitor the fluid level such as the switch mechanisms as well as translucent fluid-tubes. The buoyancy principle where different densities between the float ball and the fluid helps in controlling and monitoring the fluid level is a major principle that float ball mechanism applies.
There exists several types of float balls including stainless steel float ball. Stainless steel is an alloy of steel made up of about 10% chromium which is hard and brittle metal and able to resist tarnishing and high temperatures because of its very high melting point. In a situation where ordinary steel is used together with stainless steel, the ordinary steel would turn out to be very rusty as well as easily corroded which is not the situation with stainless steel. The use of stainless steel float balls is recommended since they are capable of withstanding very high temperatures and pressures and they are also able to provide maximum buoyancy. The stainless-steel float balls are quite strong and highly durable and their ability to resist corrosion allows them to be used in corrosive liquids to monitor the liquid level. The great durability of stainless steel float balls and other qualities makes them highly viable for all uses mostly the commercial use hence being cost efficient.
A float ball mechanism is able to monitor and control the fluid level by having a valve that is able to close the flow of the liquid into the cistern, tank or a boiler once the needed level is attained and is able to work accurately and can also be relied on. A float ball, a valve and a stem which connects the float ball and the valve are the major components of a float ball mechanism. Valves are important as they stop the flow the liquid into the cistern, tank or a boiler as the stem rises and creates a tight seal. When the level of a liquid decreases in the cistern, tank or a boiler, the float ball drops opening up the valve allowing more fluid to get in while the float ball rises as the fluid level rises until the required level is attained where the valve closes.
