dataTaker loggers were the solution provided to an oil refinery conducting a demanding field logging test application. The refinery used large catalytic reaction tubes for processing: each tube in turn contained hundreds of smaller tubes. These reactor bundles flowed liquid through one end of the reaction tube and crude oil through the other end.
The tubes had to be periodically inspected for leaks, so workers inserted fitted plugs equipped with pressure sensors, and the tubes were then air-pressurized. When the pressure in the tubes stabilized after a few minutes, technicians had to work quickly to identify any leaks in the roughly one thousand tubes inside each reactor bundle, and on average it might take personnel a minute or two to test each one.
