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.
