Abstract

PURPOSE: To provide a liquid level meter for an underground tank, which can continuously confirm the pointer position with the use of a simple construction without any movable portion, by disposing a sealed air chamber above a transparent plate, through which the pointer is observed, thereby to prevent the transparent plate from being wetted with water droplets.
CONSTITUTION: A casing 4 is made of plastics of transparent property at its upper portion 17 and is fixed to a bottom plate 13 by means of bolts 16. A transparent plate 15 constituting the inner wall if welded to the casing 4. As a result, a sealed chamber A is formed for shielding the heat above the casing 4, i.e., between the outer wall and the inner wall. As a result, the variation of the temperature is made stepwise from the transparent plate 15 through the sealed chamber A to the upper portion 17 so that considerable temperature difference is established in the transparent plate 15 thereby to prevent generation of water droplets. Thus, it is possible to provide a liquid level meter for an underground tank, which can confirm the position of a pointer in a continuously manner with the use of a simple construction.
