Level Control
Level Control

Level control is essential for many industrial and commercial applications, ranging from simple water tanks to complex chemical processing systems. Industrial applications often require control to maintain safe and efficient operations. This can be accomplished through the use of float switches or differential pressure control. Float switches are devices used to measure the level of a liquid in a tank. They work by using a float that is attached to a switch. When the float rises or falls with the level of the liquid, the switch is activated. This can then be used to trigger an alarm or shut off a pump. Differential pressure control is another level control method that uses pressure sensors to measure the difference in pressure between two points. This can be used to determine the liquid level in a tank. Differential pressure control is often used in applications requiring precise level control. At Centro, we carry a complete selection of level-control products to meet your needs. Our float switches are ideal for small-scale applications, while our radar and differential pressure control systems are designed for more demanding environments. We also offer load cells for use in weight-based level measurement. Whether you need a simple float switch or a sophisticated differential pressure system, Centro has your level control products.
