Fluid Level Control by Float Balls
Regulation of a liquid level in a cistern, tank or a boiler such as water is mostly done by apparatus referred to as float balls which can either be having a hollow space or they can be filled with a solid material. When purchasing float balls, different shapes are available in the market where one can select from including spherical or cylindrical shapes. 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. Solid material float balls are made of plastic or other material whose density is required to be less than that of water or any other liquid also used for determining 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. A major principle that is applied in all types of float balls is the buoyancy principle where different densities between the float ball and the fluid helps in controlling and monitoring the fluid level.
There exists several types of float balls including stainless steel float ball. 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 is what is generally referred to as stainless steel. Stainless steel is preferred to ordinary steel as it does not rust or corrode easily. Stainless steel float balls are quite recommended to be used where there is high pressure as well as high temperatures in any liquid and they also 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. Stainless steel float balls are more viable for use in any setting mostly the commercial setting since their great qualities makes them cost efficient.
Float ball mechanism is able to accurately monitor and control the fluid level and can be relied on since it have a valve that close the flow of the liquid into the cistern, tank or a boiler once the needed level is attained. The float ball mechanism is made up of the float ball, a valve and a stem which connects the float ball to the valve. 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. Once the fluid is emptied from 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.
