In collaboration with the Corporation for Research- and Developing Services, BASF in Ludwigshafen has recently developed a new testing machine for detecting liquid in pipes and machinery, which can be used quickly and easily. The new piece of equipment sends weak gamma rays through the pipes and drums of machinery, which then bounce back at different resonances depending on the whether there is any fluid present or not. An in-built computer measures the readings and compares them with saved patterns, in order to detect any of liquid such as chemicals that may have been left in the pipes and drums of machinery.
