A float operated level control is typically used on which type of equipment?

Float-operated level control devices are primarily used in small boilers because they offer a simple and effective means of regulating water levels in applications where precise control is not as critical, and space constraints often apply. In smaller systems, these float controls can reliably manage the water level with minimal complexity and maintenance, allowing for straightforward operation.

In larger boilers, while float-operated controls can still be employed, they might be supplemented or replaced by more advanced methods such as electronic level sensors or pressure level controls due to the larger volume of water and the increased demands for accuracy and responsiveness. Hence, the float control systems are less commonly the primary choice in larger boiler applications.

Therefore, the use of float-operated level controls is more characteristic of small boilers where their inherent simplicity, cost-effectiveness, and ease of maintenance align well with the operational requirements.
