On a steam raising boiler there are three clear applications for level monitoring devices: Level control - To ensure that the right amount of water is added to the boiler at the right time. Low water alarm - For safe boiler operation, the low water alarm ensures that the combustion of fuel does not continue if the water level in the boiler has dropped to, or below a predetermined level.Get Price

When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.Get Price
The control of the boiler drum level is tricky and even the best tuned control systems cannot always prevent a low-water condition. The "water level" in a steam drum is actually a fairly unstable compressible mixture of water and steam bubbles that will shrink and swell with pressure changes and will actually shrink momentarily when more "cold" feedwater is added.Get Price
