摘要： A water level detection method via video recognition, includes steps of obtaining an image of a water level gauge from a camera; wherein the water level gauge includes multiple two-dimensional barcodes; and determining a water level according to the two-dimensional barcodes. When a body of water partly covers the water level gauge, the body of water would cover some of the two-dimensional barcodes, leaving the rest of visible two-dimensional barcodes corresponding to the water level. When the water is clear, the two-dimensional barcodes underwater would be visible yet at the same time indecipherable due to distorted barcode scales. This way, the present invention is able to avoid accidentally counting two-dimensional barcodes underwater, and thus more accurately and robustly detect water levels.

摘要： A system provides a level detector with a multi-axis magnetometer sensor that senses movement of a magnet connected to a float within a vessel. A temperature sensor may assist in compensating for changes to the magnetic field due to ambient temperature. Output from the sensor is provided to a local data processing unit which provides level data to a local display. The local data processing unit sends data through a communications port to a remote system which can track level remotely as well as assimilate and uniquely characterize data from other vessels to provide more accurate level measurement by the local processing unit.

摘要： A system for monitoring a fill level of a container includes a wireless module disposed on the container including an enclosure, a processor and a wireless transceiver disposed within the enclosure, and a cable mounted to the enclosure. A first pressure sensor is attached to an end of the cable distal from the enclosure and a second pressure sensor is attached to an opposite end within the enclosure. The enclosure is mounted outside of the container. The cable is inserted into the container such that the first pressure sensor is disposed near a bottom of the container. The first pressure sensor measures a pressure at the bottom of the container. The second pressure sensor measures a pressure outside of the container. The readings from the first pressure sensor and the second pressure sensor are cross-correlated to determine a net pressure for use in calculating the fill level of the container.
