ABSTRACT:
A liquid level gauge or like meter designed to provide a reading of prolonged duration, is operated by means of a push-button which, upon depression by exertion of a push on its head, activates the basic sensor element of the meter which controls its index. The latter is located inside the push-button, under the head thereof which protects it against shocks and soil; it can be viewed through this head which is of transparent material. The index has a section which is carried by the transparent head of the push-button and is movable therewith. The required prolonged duration readability of the index is available after release of the push-button head.
