Los Angeles SNAME Discusses Liquid Level Gauging By Radar

The Los Angeles Metropolitan Section of The Society of Naval Architects and Marine Engineers gathered for a recent meeting aboard the converted cruise ship Princess Louise berthed in Los Angeles Harbor. The subject of the e v e n i n g ' s technical paper, "Radar — A New Approach to Level Gauging," is as current to ship technology as the joggled and riveted frames and webs of the Princess Louise are archaic.

Gorjan Martensson of Saab- Scania prepared and presented the timely paper to acquaint those present with his company's solution to the problem of accurately and reliably measuring liquid levels in ship cargo tanks. He began by outlining the various measuring systems in current use, and detailed the qualities and deficiencies he felt were inherent to each. The author went on to detail the theory of the Saab-Scania radar system that, according to Mr. Martensson, overcomes the problems of existing systems by limiting the incursion of the device into the harsh environment of tanks to radio frequency waves.

The author concluded his presentation by candidly describing the trials associated with developing a new system for shipboard use.
