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 container for containing generally flowable solid or liquid materials and capable of being hung in an inverted position is provided. The container includes a container body and a protruding hook-shaped handle, wherein the hook-shaped handle is arranged in L-shaped or inverted-hook configuration according to which a hooking space is formed oriented towards a top rim of the container. By hanging the container in an inverted position, the container is able to rapidly rinse and dry out after washing, while keeping the container top rim in the air and avoiding contamination of the container. The hook-shaped handle further allows the container to be conveniently and temporarily hung from a bowl sidewall, taking up no countertop or table space. The hook-shaped handle preferably protrudes from the base of the container to contribute to container stability when placed in an upright position.

A stretchable capacitance sensor having multiple components for communicating signals to a data acquisition system for reconstructing an image of an area or object located in a subject being sensed, and for calculating the shape or conformity that it is in. The stretchable sensor consists of an inner layer of plates that provide the capacitance data, a middle layer of plates that provide the geometry-sensing data, and an outer layer of plates that serves as the shielding ground layer. The configuration of all three components can be variably changed to increase the capacitance data channels, increase or decrease flexibility and stretchability of the sensor, and increase the spatial resolution of the geometry sensing feature. The sensor is adapted to communicate signals to a data acquisition system for providing an image of the area or object between the capacitance plates.

Methods and systems for determining a base field prover volume of a field prover include connecting together a transfer meter assembly, a master prover, and the field prover in series. A flow of fluid at a first flow rate is provided and a calibration sequence is performed at the flow rate. The calibration sequence includes counting pulses generated by the transfer meter assembly over a duration of each pass of the master prover and a pass of the field prover. An intermediate calibrated field prover volume is determined from a ratio of the field prover pulse count to the average master prover pulse count, multiplied by a base master prover volume. The calibration sequence can be repeated to provide at least three intermediate calibrated field prover volumes at the first flow rate. The calibration sequence can be repeated at different flow rates to arrive at the base field prover volume.
