ABSTRACT:
A software-based water level monitoring and control system, preferably for use with conventional steam boilers, is disclosed. The system includes software for monitoring and recording system functions, safety features, diagnostic testing histories, and other functions. The water level system is employed to monitor and/or regulate one or more operating parameters of the boiler, such as water levels within the boiler. In response to the boiler system testing of low-water cut-off, auxillary low-water cut-off, and pressure vessel float operation and functionality, the software builds histories and other data compilations. The extensive electronic information permits a user that accesses the water level control system to, for example, view the data compilations and to monitor the status of the system. In this manner, real-time information, as well as the historical data, are available to accomplish the regulation of key parameters in the boiler.
