Acoustic volume indicators for determining liquid or gas volume within a container comprise a contactor to vibrate a container wall, a detector to receive vibration data from the container wall, a processor to convert vibration data to frequency information and compare the frequency information to characteristic container frequency vs. volume data to obtain the measured volume, and an indicator for displaying the measured volume. The processor may comprise a microprocessor disposed within a housing having lights that each represent a particular volume. The microprocessor is calibrated to provide an output signal to a light that indicates the container volume. The processor may comprise a computer and computer program that converts the data to frequency information, analyzes the frequency information to identify a peak frequency, compares the peak frequency to the characteristic frequency vs. volume data to determine the measured volume, and displays the measured volume on a video monitor.

A sensor assembly is provided for detecting a concentration of a fluid. The sensor assembly includes a sensing unit and a cover assembly. The sensing unit includes a transmitter configured to transmit a signal into a sensing volume and a receiver configured to receive the signal after the signal passes through a portion of the sensing volume. The cover assembly at least partially encloses the sensing volume and is substantially impermeable to a gas portion of the fluid. The cover assembly includes apertures defined therein which are permeable to the gas portion of the fluid. A first plurality of apertures are defined along a top surface of the cover assembly.

Systems, methods, and computer-readable media are disclosed for detection of overfilled containers in sortation systems. In one embodiment, an example container capacity detection system for use with an item sortation machine may include a first sensor positioned to detect a remaining capacity of a first container in the item sortation system, and a controller. The controller may be configured to determine, using the first sensor, that the remaining capacity of the first container is less than or equal to a first threshold, and to send a signal.
