Definition of SK All rotameter tubes, accessories, complete assemblies as well as many spare parts have an associate SK number. This number is use to efine component compatibility. Please note that only proucts with the same SK number are compatible with each other. Important: The UPW Rotameter Family oes not completely follow this structure in that the UPW SK numbers shoul only be use for sizing electronic feeback accessories. The UPW subcomponents are specifically esigne for this prouct line an iffer from the stanar subcomponents. Optional scales, unless specifically esigne for the UPW tube, will therefor not rea accurately.
