发明名称 HEAD FOR THE DETECTION OF A LEVEL BY THE HYDROSTATIC EFFECT WITH PROTECTION
摘要 <p>The head for the hydrostatic detection of a liquid level includes a main enclosure which is divided by a membrane into two chambers, one of which communicates with a supply of air under pressure, while the other is joined to a probe that is immersed deeply into the liquid. That connection is made, in this case, by the intermediary of an auxiliary enclosure that also contains a primary chamber that communicates with the inlet of the air under pressure, and a secondary chamber which is separated from the primary chamber by a membrane. That membrane forms one piece with a valve mounted between the chamber and a small connecting conduit connected with a probe, which prevents any ill-timed rise of the liquid inside the device, in the case of the disappearance of the compressed-air supply, and which makes it possible, at the same time, to install the detector head above the tank.</p>
