Title: Improved volume measuring system
Inventor: POND JOHN BROWN
IPC: G01F17/00
Filed: 1984-06-29
Abstract: The method comprises applying to the gas or vapour within the confined space or container repeated compressions of predetermined waveform by means of a barrier or diaphragm; generating electrical signals representative of the resultant variation of pressure within the confined space or container; repeatedly sampling said electrical signals at regular predetermined instants, or over regular predetermined time ranges, corresponding to predetermined points or regions of said waveform; combining or integrating the sampled signals to generate thereby a time-averaged output signal; and calculating the free volume of the confined space or container from the output signal thus obtained. In one embodiment, the apparatus comprises the diaphragms of a moving coil loudspeaker 51 for applying repeated compressions to said confined space V1 with a predetermined waveform a pressure-sensitive transducer M1 for measuring pressure changes within the volume which is itself to be measured; electrical circuit means connected to said pressure- sensitive transducer and to said drive means, means 9, 11, 10, 12 for sampling the electrical output of said pressure-sensitive transducer at predetermined times related to the frequency at which the diaphragm means is driven and means 15, 16 for generating a time-averaged output signal from the signals generated by said electrical circuit means; and means 6 for determining from said time- averaged output signal a value representative of the free volume being measured. A reference volume V2 may be provided, and the state of fill of space V1 may be indicated. Portable measuring apparatus is also described (Figs. 2-3, not shown).
