Title:
DEVICE FOR CHECKING STATE OF LIQUID, AND LIQUID TANK WITH THE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/111469
Kind Code:
A1
Abstract:
An aging checking device (2) comprises: a sight glass (3) for checking the aging degree of biofuel stored in a fuel tank through color variation of the biofuel; and first and second comparison parts (4a, 4b) each including three color samples (11a to 11c) corresponding to certain aging degrees of the biofuel and arranged along the sight glass (3), wherein the aging degree of the biofuel is determined by looking at the color samples (11a to 11c) through the biofuel inside the sight glass (3). If the surface of the biofuel is lowered or a moisture layer rises to the surface of the biofuel, the arrangement of the color samples (11a to 11c) of the first and second comparison parts (4a, 4b) can be reversed to cope with that.
