  • Patent number: 7992527
    Abstract: A water feed controller which can provide for the addition of a preset fixed amount of water to be added after a low water condition is removed. This system provides for a preset fixed amount of water to be added to a boiler above the amount which triggers the low water condition. This generally inhibits excess cycling from the boiler operating at its minimum safe water level as well as inhibiting overfilling of the boiler. Further, there is discussed a water feed controller which can measure the amount of water added over a prior predetermined period (such as 30 days) which serves as a floating window of time so that a leak or other condition resulting in overly frequent filling can be detected quickly.

  • Patent number: 7706989
    Abstract: Systems and methods for evaluating probe signal level readings in a manner that allows a low water detector to distinguish between a probe that is under a fluid level, or is above the fluid level and either being splashed or is within a foam. Low water detectors which utilize these systems and methods are also provided. The detectors generally utilize a representative probe reading, and a dynamic indicator between probe readings, for a set of probe readings taken in a time period to detect low water levels, foam, or surge.
