The marine float level controller is a vital instrument in fluid control systems and is available in various types. These differences depend on the working principles and application ranges. Thus, knowing the kinds helps the buyer decide on the suitable float valve for specific industries.
Generally, the level controllers use buoyant floats linked to a control mechanism. The float rises and falls with fluid levels, actuating the system to maintain desired levels. So, the following discusses some of the predominant types of marine float-level controllers:
The magnetic float-level controllers are widely used because of their high precision. These controllers have a float that moves in the liquid, and magnets inside the float operate the sensors externally. Common in oil and chemical industries due to their reliability and robustness in extreme conditions. They offer non-contact measuring with minimal maintenance, making them perfect for long-term operations.
The hydrostatic pressure float-level controllers work based on changes in pressure exerted by the liquid column above the float. Hence, a submersible pressure sensor is used to measure the liquid level. These types are highly accurate and are commonly used in water treatment and food processing industries. Also, they are fit for applications where precise control is crucial.
The conventional mechanical float-level controllers use the simple buoyant principle to operate. In a detailed explanation, these controllers consist of a float that rises or falls with the liquid level, which in turn opens or closes a valve. These types suit many applications, such as freshwater and fuel oil service. Moreover, they are reliable and cost-effective solutions. However, they are less accurate compared to magnetic and hydrostatic pressure float controllers.
The electrical float-level controllers utilize one or more conductive floats to detect liquid levels. This controller completes a circuit when the float reaches a predetermined level. Mostly, they are found in applications where the liquid has conductive properties. The liquid includes water and wastewater treatment plants. They are simple and cost-effective, but not suitable for non-conductive liquid measurements.
In addition, at the core of these float-level controllers, the selection depends on the industry special needs and the liquids involved. While mechanical floats are fit for basic applications, the electrical kinds are suitable for conductive liquids only. The magnetic and hydrostatic pressure float controllers provide non-contact and pressure-based measurements for more complex tasks. So, understanding the diverse float controllers allows one to choose the right controller for each specific application.
