Fluid Level Control by Float Balls
Float balls are materials that have a hollow space or can be solid material that is 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. Float balls are available in the market in many different shapes such as they can be spherical or cylindrical. Determination of the liquid level or water level can be done by use of float balls that have a hollow space to enhance their buoyancy. Float balls that have been filled by solid material made of plastic or other material whose density should be lower than that of the liquid to enhance buoyancy are also used to determine the liquid level. The float balls can also be incorporated into switch mechanisms as well as translucent fluid-tubes to help in fluid level surveillance. All the float balls depend on the principle of buoyancy 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. 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. 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 great strength as well as durability of stainless steel float balls together with their ability to resist corrosion makes it possible to use them in controlling and monitoring the fluid levels. 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.
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. A float ball works together with 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.
