Title:
MEASURING DEVICE FOR VOLUME OF LIQUID IN CONTAINER THROUGH TEMPERATURE CORRECTION AND CONTAINER
Document Type and Number:
WIPO Patent Application WO/2017/035809
Kind Code:
A1
Abstract:
Provided are a measuring device for the volume of liquid in a container through temperature correction and a container (7). The measuring device is used for the measurement of the volume of liquid in the container (7), comprising: a compression piece (1) of a fixed and known section size, wherein a stop device (3) is provided on the compression piece (1) and can be connected to the container (7) in a sealing manner so as to form a sealed space in the container (7). The gas in the sealed space can be compressed through the movement with respect to the container (7), and the stop device (3) makes the movement distance of the compression piece (1) fixed and known. The device also comprises an air pressure sensor (4) for detecting the air pressure value in the sealed space before and after compression, and temperature detection devices (61, 62) for detecting the temperature value of the gas in the sealed space. The measuring device can obtain the volume of liquid in the container (7) to be measured based on the above-mentioned values of atmospheric pressure, temperature, section size and displacement. The measuring device can eliminate the influence of temperature on the measurement result, and increase measurement accuracy of the volume of liquid in the container.
