Bendix electro-span (Apr, 1956)

Liquid levels monitored hundreds of miles from your central office by Bendix electro-span!

Important storage reservoirs for water, crude oil, gas, brine and other liquids are located in many remote and isolated sections of this country. It takes crews of men stationed at these points to keep a constant check of volumes and to open and close valves to balance supply and demand. The work is lonely, expensive to maintain, and sometimes dangerous.
