Ullage, oil/water interface, cargo temperature, tank bottom dryness and oxygen levels in inert gas are some of the measurements that can be taken, with great accuracy, with this liquid and dry cargo sampling equipment. The Portable Sonic/Electronic tapes are battery-driven and require no external power sources. These units require no correction for cargo specific gravity and are of solid state design and intrinsically safe. The tapes are dual marked with feet and inches on one side and meters on the other. Tapes vary in length from 50 ft. to 300 ft. depending on the model, so please specify desired tape length when ordering.
