Abstract: An assembly for sensing corrosion of a member is disclosed. The assembly has a housing having a bottom surface that is external-surface-disposable on the member, and a sensor array disposed at least partially in the housing, the sensor array including a first sensor and a second sensor. The first sensor and the second sensor are magnetoresistive sensors. The first sensor is disposed at up to 3 centimeters from the bottom surface of the housing. The second sensor is disposed at between 1 inch and 8 inches from the bottom surface of the housing.

Abstract: A method is disclosed. The method includes providing a sensor attached to a vehicle, controlling the vehicle to move toward a system, using the sensor to sense data, providing the sensed data to a detection module including computer-executable code stored in non-volatile memory, and controlling the sensor and the vehicle to perform a raster scan when the detection module detects a variation in the sensed data. The method also includes providing sensed raster scan data to the detection module, using the detection module to generate a plurality of probability distribution curves based on the sensed raster scan data, and using the detection module to generate a vector based on the plurality of probability distribution curves. The vector points to a location of the system.

Abstract: A system for sensing flow material in a fluid-holding structure is disclosed. The system has an assembly including a housing, a communication device disposed at least partially in the housing, a controller disposed at least partially in the housing, a sensor array disposed at least partially in the housing, and an external-surface-mounting attachment portion configured to non-intrusively attach the assembly to a surface. The system also has a user interface configured to display a graphical element. The sensor array includes a pressure sensor, a density sensor, a corrosion sensor, and a vibration sensor. The controller controls the communication device to transmit sensed data collected by the sensor array to the user interface. The sensed data includes at least one of a density data sensed by the density sensor and a corrosion data sensed by the corrosion sensor. Display of the graphical element varies based on the sensed data.
