What is a Water Level Control & What is its function?
Water level controls are designed to maintain the correct water level in your boiler, especially under times of heavy load. Some have an added feature of also being a Low Water Cut Off (LWCO) and is a required safety device required to safely operate a boiler.
Different Types of Water Level Controls & How to Choose
WARE’s wide selection of water controls includes everything your boiler needs to keep the water at the right level, and operating with maximum efficiency and safety. There are different brands and methods for controlling water level. Such as a float type, probe type, or differential pressure.
The Role Water Level Controls Play in a Boiler
Water level controls refer to the systems in your boiler that monitor the water level, and open the feedwater valve or start a pump to add more water as needed. If the water level in a boiler gets too high, the boiler loses steam pressure, steam quality and efficiency. If the water level gets too low, the boiler can be damaged or even explode.
