  • Patent number: 11231311
    Abstract: Systems and methods for determining a fill level of a fluid within a fluid vessel, an identity of the fluid, and/or a condition of the vessel wall are disclosed. To determine a fluid fill level, at least one acoustic sensor is positionable substantially on an exterior sidewall of a vessel containing fluid. A computerized device is in communication with the at least one acoustic sensor. A processor of the computerized device receives a detection signal from the at least one acoustic sensor and communicates an alert of the detection signal, which can be used to identify a fill level of the fluid. The detection signal, along with other measured information, can be used to identify the material type of the fluid. A condition of the vessel wall may be determined based on an attenuation signal when two acoustic sensors are used, one being positioned angular to the vessel wall.

  • Patent number: 11143533
    Abstract: Systems and methods for determining a weight of a quantity of fluid, or a flow rate of the fluid by weight. An acoustic sensor positioned on an exterior wall of a vessel containing the fluid determines a fill level of the fluid. A computerized device calculates a weight of the quantity of fluid using a size of the vessel, the determined fill level, a temperature of the fluid, and the fluid identity and/or a fluid density. Flow rate of the fluid through a pipe is determined using two or more acoustic sensors positioned at different locations on a pipe, and a temperature sensor. A computer calculates a differential time of flight of the fluid based on readings of the acoustic sensor, a distance therebetween, the temperature sensor, the pipe volume, and the fluid identity and/or a fluid density. A flow by weight of the quantity of fluid is determined.
