Abstract

PURPOSE:To detect a level with high accuracy and simple construction, by locating a laser source on one side of a case sealing a gas and a liquid and a photodetector on the counter surface and detecting the amount of transmitted light. CONSTITUTION:In a case 3, a gas 1 and a transparent liquid 2 are sealed and a laser source 4 is located on the upper side of the case 3 and a photodetector 5 is located at the bottom. When the case is tilted, since an incident angle 7 of a beam 6 to the liquid 2 changed, the amount of incident light to the photodetector 5 is changed. Thus, the level can be detected with high accuracy and simple construction.
