Stephen Carson-Rowland has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8746060
    Abstract: A method, useful for wastewater liquid level indication rods in wastewater treatment facilities, of correcting the readings from the rod's electrode based liquid level sensors for inaccuracies and distortions caused by fat, oil, and grease (FOG) contaminant build up. The method may also detect how the electrical signals change as the liquid levels progress ever higher above the level of the measuring electrode of interest. These methods allow for the creation of improved wastewater liquid monitoring systems and management systems that can warn when cleaning is needed, help prevent pump burnout, overflow, and address other common wastewater management problems.
    Type: Grant

  • Patent number: 8684700
    Abstract: Disclosed is a liquid level indicator suitable for use with an electrical power source comprises: a liquid level indication rod at least partially immersed in the liquid, the liquid level indication rod including a plurality of electrical contacts disposed on a surface of a non-conductive material; a level indicator transmitter in electrical communication with the liquid level indication rod and with the electrical power source, the level indicator transmitter functioning to measure current flow from each of the plurality of contacts to a ground in the liquid so as to determine which of said plurality of electrical contacts lie beneath a surface of the liquid.
