US Patent 7470060 Detection apparatus for measuring fluid in a vessel

A detection apparatus for measuring fluid in a vessel, comprising: at least one processor for receiving, processing and storing data from sensors in the vessel, at least one vertical support disposed within the vessel and at least one pair of sensors connected to the at least one vertical support. The sensors continuously provide measurement data to the processor, wherein the processor synchronously polls measurement data from the sensors, continuously calculates values, and compares the calculated values to at least one predetermined range of values for the fluid in the vessel to identify whether the calculated values are within the predetermined values. The processor communicates the compared value to a data collector.
