ABSTRACT:
Apparatus for ascertaining the upper level of oil or another liquid in a shallow or deep tank has a perforated vertical conduit which is installed in and extends to the bottom of the vessel. A vertical pipe is adjacent to the conduit and is sealed from the contents of the tank. The pipe contains electrical components which are connected to an indicating instrument and include a row of spaced-apart electric switches actuatable by a permanent magnet in a float which is movable up and down within the confines of the conduit so that the instrument receives signals denoting the actuated switch or switches and thus enables an attendant to ascertain the liquid level in the tank. The pipe and the conduit consist of several superimposed sections having flanges which are bolted or otherwise separably connected to each other to allow for convenient dismantling of the pipe and conduit and their transfer to storage or to another tank.
